The controller is a high power electronics device.Serious damage,including fire

follow the instructions in this section very carefully.Any problem due to wiring

errors may have very serious consequences and will not be covered by the product’s

warranty.

Power Connections

Power connections are described in the controller model’s datasheet.Depending on the model type,power connection is done via wires,fast-on tabs,screw terminals or copper bars coming out of the controller.

Controllers with wires as power connections have Ground (black),VMot (red)power ca- bles and a Power Control wire fyellowi.The power cables are located at the backend of the controller.The various power cables are identified by their position,wire thickness and color:red is positive(+),black is negative or ground (-).

Controllers with tabs,screw terminals or copper bars have their connector identified in print on the controller.

Connecting Power and Motors to the Controller lRoboteQ
Controller Power

The controller uses a flexible power supply scheme that is best described in Figure 1-1. In this diagram,it can be seen that the power for the Controller’s internal microcomput- er is separate from this of the motor drivers.The microcomputer circuit is connected to a DC/DC converter which takes power from either the Power Control input or the VMot input.A diode circuit that is included in most controller models,is designed to automat- ically select one power source over the other and lets through the source that has the highest voltage.

FIGURE 1-1.Representations of the controller’s Internal Power Circuits

When powered via the Power Control input only,the controller will turn On,but motors will not be able to turn until power is also present on the VMot wires or Tab.

The Power Control input also serves as the Enable signal for the DC/DC converter.When floating or pulled to above 1V,the DC/DC converter is active and supplies the controller’s microcomputer and drivers,thus turning it On.When the Power Control input is pulled to Ground,the DC/DC converter is stopped and the controller is turned Off.

The Power Control input MUST be connected to Ground to turn the Controller Off.For turning the controller On,eventhough the Power Control may be left floating,whenever possible pull it to a 12V or higher voltage to keep the controller logic solidly On.You may use a separate battery to keep the controller alive as the main Motor battery discharges.

On the high voltage controller that is rated above 60V,a zener diode is inserted between the VMot supply and the DC/DC converter.This causes a voltage drop that keeps the volt- age at the converter’s input within its maximum operating range.However,this diode also

increases by around 20V the low voltage threshold at which the controller will start operat- ing when powered from VMot alone.

charging on page 25.”Capacitor precharging”

Roboteq controllers operate in an environment where high currents may circulate in

unexpected manners under certain condition.Please follow these instructions.Roboteq reserves the right to void product warranty if analysis determines that damage is due to improper controller power connection.

Mandatory Connections

It is imperative that the controller is connected as shown in the wiring diagram provided in the datasheet in order to ensure safe and trouble-free operation.All connections shown as thick black lines are mandatory.

· Connect the thick black wire(s)or the ground terminal to the minus (-)terminal of the battery that will be used to power the motors.Connect the thick red wire(s)or VMot terminal to the plus (+)terminal of the battery.The motor battery may be of 12V up to the maximum voltage specified in the controller model datasheet.

·The controller must be powered On/Off using switch SW¹on the Power Control

wire/terminal.Grounding this line powers Off the controller.Floating or pulling this

line to a voltage will power On the controller.(SW1 is a common SPDT 1 Amp or

more switch).

Use a suitable high-current fuse F¹as a safety measure to prevent damage to the wiring in case of a major controller malfunction.(Littlefuse ATO or MAXI series).

· The battery must be connected in permanence to the controller’s Red wire(s)or VMot terminal via a high-power emergency switch SW2 as an additional safety

measure.Partially discharged batteries may not blow the fuse,while still having

enough power left to cause a fire.Leave the switch SW2 closed at all times and

open only in case of an emergency.Use the main On/Off switch SW1 for normal operation.This will prolong the life of SW2,which is subject to arcing when open- ing under high current with the consequent danger of contact welding.

If installing in an electric vehicle equipped with a Key Switch where SW2 is a con- tactor,and the key switch energizes the SW2 coil,then implement SW1 as a relay. Connect the Key Switch to both coils of SW1 and SW2 so cutting off the power to the vehicle by the key switch and SW2 will set the main switch SW1 in the OFF

position as well.

IRoboteQ

Controller Powering Schemes

Connection for Safe Operation with Discharged Batteries (note 1)

The controller will stop functioning when the main battery voltage drops below 7V.To en- sure motor operation with weak or discharged batteries,connect a second battery to the Power Control wire/terminal via the SW1 switch.This battery will only power the control- ler’s internal logic.The motors will continue to be powered by the main battery while the main battery voltage is higher than the secondary battery voltage.

Use precharge Resistor to prevent switch arcing (note 2)

Insert a 1000hm,5W resistor across the SW2 Emergency Switch.This will cause the con- troller’s internal capacitors to slowty charge and maintain the full battery voltage by the time the SW2 switch is turned on and thus eliminate damaging arcing to take place inside the

switch.Make sure that the controller is tumed Off with the Power Control wire grounded while the SW2 switch is off.The controller’s capacitors will not charge if the Power Control wire is left fioating and arcing will then occur when the Emergency switch is turned on.

Protection against Damage due to Regeneration (notes 3)

The voltage generated by motors rotating while not powered by the controller can cause serious damage even if the controller is Off or disconnected.

· Use the main SW1 switch on the Power Control wire/terminal to turn Off and keep Off the controller.In this way the controller cannot be powered up under any un- wanted circumstances.

· Countermeasures should betaken to deal with any regeneration power if the bat- tery or BMS system does not support energy to return back to it.

· Disconnecting the controller from the battery while motors are rotating could lead to a serious damage.In this case a regeneration brake system is needed.

Connect Case to Earth if connecting AC equipment (note 4)

If building a system which uses rechargeable batteries,it must be assumed that periodi- cally a user will connect an AC battery charger to the system.Being connected to the AC main,the charger may accidentally bring AC high voltage to the system’s chassis and to the controller’s enclosure.A similar danger exists when the controller is powered via a power supply connected to the mains.

Some controller models in metallic enclosures are supplied with an Earth tab,which per mits earthing the metal case.Connect this tab to a wire connected to the Earth while the charger is plugged in the AC main,or if the controller is powered by an AC power supply or is being repaired using any other AC equipment (PC,Voltmeter etc.)

Avoid Ground loops when connecting l/O devices (note 5)

When connecting a PC,encoder,switch or actuators on the VO connector,be very careful that you do not create a path from the ground pins on the VO connector and the battery

minus terminal.Should the controller’s main Ground wires (thick black)or terminals

be disconnected while the VMot wires (thick red)or terminals are connected,the high current would flow from the ground pins,potentially causing serious damage to the controller and/or your external devices.

· Do not connect a wire between the l/0 connector ground pins and the battery mi- nus terminal.Look for hidden connection and eliminate them.

· Have a very firm and secure connection of the controller ground wire and the bat- tery minus terminal.

· Do not use connectors or switches on the power ground cables.

Connecting Power and Motors to the Controller RoboteQ
Important Warning

Do not rely on cutting power to the controller for it to turn Off if the Power Control is left floating.If motors are spinning because the robot is pushed or because of

inertia,they will act as generators and will turn the controller On,possibly in an un- safe state.ALWAYS ground the Power Control wire terminal to turn the controller Of and keep it Off.

Important Warning

Unless you can ensure a steady voltage that is higher than 7V in all conditions,it is

recommended that the battery used to power the controller’s electronics be sepa-

rate from the one used to power the motors.This is because it is very likely that the motor batteries will be subject to very large current loads which may cause the voltage to eventually dip below 7V as the batteries’charge drops.The separate backup power supply should be connected to the Power Control input.

Connecting the Motors

Refer to the datasheet for information on how to wire the motor(s)to a particular motor controller model.

After connecting the motors,apply a minimal amount of power using the Roborun PC util- ity with the controller configured in Open Loop speed mode.Verify that the motor spins in the desired direction.Immediately stop and swap the motor wires if not.

In Closed Loop Speed or Position mode,beware that the motor polarity must match this of the feedback.If it does not,the motors will runaway with no possibility to stop other than switching Off the power.The polarity of the Motor or of the feedback device may need to be changed.

Important Warning

Make sure that your motors have their wires isolated from the motor casing.Some motors,particularly automotive parts,use only one wire,with the other connected to the motor’s frame.If you are using this type of motor,make sure that it is mount– ed on isolators and that its casing will not cause a short circuit with other motors

and circuits which may also be inadvertently connected to the same metal chassis.

Single Channel Operation

Dual channel Brushed DC controllers may be ordered with the -S(Single Channell)suffix.

The two channel outputs must be paralleled as shown in the datasheet so that they can drive a single load with twice the power.To perform in this manner,the controller’s Power Transistors that are switching in each channel must be perfectly synchronized.Without

this synchronization,the current will flow from one channel to the other and cause the destruction of the controller.

26 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Power Fuses

The single channel version of the controller incorporates a hardware setting inside the

controller which ensures that both channels switch in a synchronized manner and respond to commands sent to channel 1.

Important Warning

Before pairing the outputs,attach the motor to one channel and then the other.Veri- fy that the motor responds the same way to command changes.

Power Fuses

For low Amperage applications (below 30A per motor),it is recommended that a fuse be inserted in series with the main battery circuit as shown in Figure 1-2 on page 24.

The fuse will be shared by the two output stages and therefore must be placed before the Y connection to the two power wires.Fuse rating should be the sum of the expected cur rent on both channels.Note that automotive fuses above 40A are generally slow,will be of limited effectiveness in protecting the controller and may be omitted in the high current application.The fuse will mostly protect the wiring and battery against after the controller has failed.

Important Warning

Fuses are typically slow to blow and will thus allow temporary excess current to flow through them for a time (the higher the excess current,the faster the fuse will blow).This characteristic is desirable in most cases,as it will allow motors to draw surges during acceleration and braking.However,it also means that the fuse may not be able to protect the controller.

Wire Length Limits

The controller regulates the output power by switching the power to the motors On and Off at high frequencies.At such frequencies,the wires’inductance produces undesirable effects such as parasitic RF emissions,ringing,and overvoltage peaks.The controller has built-in capacitors and voltage limiters that will reduce these effects.However,should the wire inductance be increased,for example by extended wire length,these effects will be amplified beyond the controller’s capability to correct them.This is particularty the case for the main battery power wires.

Important Warning

Avoid long connection between the controller and power source,as the added in- ductance may cause damage to the controller when operating at high currents.Try extending the motor wires instead since the added inductance is not harmful on

this side of the controller.

If the controller must be located at a long distance from the power source,the effects of the wire inductance may be reduced by using one or more of the following techniques:

Connecting Power and Motors to the Controller lRoboteQ

· Twisting the power and ground wires over the full length of the wires

· Use the vehicle’s metallic chassis for ground and run the positive wire along the surface

· Add a capacitor (10,00OuF or higher)near the controller

Electrical Noise Reduction Techniques

As discussed in the above section,the controller uses fast switching technology to control the amount of power applied to the motors.While the controller incorporates several cir- cuits to keep electrical noise to a minimum,additional techniques can be used to keep the noise low when installing the controller in an application.Below is a list of techniques you can try to keep noise emission low:

·Keep wires as short as possible

·Loop wires through ferrite cores

· Add snubber RC circuit at motor terminals

· Keep controller,wires,and battery enclosed in a metallic body

Battery Current vs.Motor Current

The controller limits the current that flows through the motors and not the battery cur-

rent.Current that flows through the motor is typically higher than the battery current.This counterintuitive phenomenon is due to the “flyback”current in the motor’s inductance.In some cases,the motor current can be extremely high,causing heat and potentially dam- age while battery current appears low or reasonable.

The motor’s power is controlled by varying the On/Off duty cycle of the battery voltage 16,000 times per second to the motor from 0%(motor off)to 100 (motor on).Because of the inductive flyback effect,during the Off time current continues to flow at nearly

the same peak-and not the average -level as during the On time.At low PWM ratios, the peak current-and therefore motor current -can be very high as shown in Figure 1-4, on next page.

The relation between Battery Current and Motor current is given in the formula below:

Motor Current =Battery Current /PWM ratio

FIGURE 1-3.Current flow during operation

28 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Measured and Calculated Currents

FIGURE 1-4.Instant and average current waveforms

The relation between Battery Current and Motor current is given in the formula below:

Motor Current =Battery Current /PWM Ratio

Example:If the controller reports 10A of battery current while at 10%PWM,the current in the motor is 10/0.1=100A.

Measured and Calculated Currents

Some Roboteq Brushed DC motor controllers,have current sensors for measuring the

battery current and estimate the motor current.At 20%PWM and above,the motor cur rent is computed using the formula above.Below 20%,and approaching 0%,this method causes unstable and imprecise readings.At these levels the formula used is

Motor Current =Battery Current /0.20

This approximation creates a more stable value but one that is increasingly inaccurate as the PWM approaches 0%.This approximation produces usable value nevertheless.

Roboteq’s Brushless motor controllers use sensors on the motor outputs or/and on the battery ground terminal.Controllers using sensors on the battery terminal outputs suffer the same limitation at low PWM as discussed above.

Controllers with sensors on the motor terminals provide accurate motor current sensing in all conditions,and provide a good estimate battery current value.Some controller models have sensors on the motor and on the battery terminals,and provide the most accurate current sensing as all are actually measured values.

Whether sensors are on the motor or/and battery terminals can be found in the product’s datasheet

Important Warning

Do not connect a motor that is rated at a higher current than the controller.

Connecting Power and Motors to the Controller lRoboteQ
Power Regeneration Considerations

When a motor is spinning faster than it would normally at the applied voltage,such as when moving downhill or decelerating,the motor acts as a generator.In such cases,the current will flow in the opposite direction,back to the power source.

It is therefore essential that the controller is connected to rechargeable batteries.If a pow- er supply is used instead,the current will attempt to flow back in the power supply during regeneration,potentially damaging it and/or the controller.

Regeneration can also cause potential problems if the battery is disconnected while

the motors are still spinning.In such a case,the energy generated by the motor will

keep the controller On,and depending on the command level applied at that time,the regenerated current will attempt to flow back to the battery.Since none is present,the voltage will rise to potentially unsafe levels.The controller includes an overvoltage pro- tection circuit to prevent damage to the output transistors (see “Using the Controller

with a Power Supply”belowl.However,if there is a possibility that the motor could be made to spin and generate a voltage higher than 40V,a path to the battery must be pro- vided,even after a fuse is blown.This can be accomplished by inserting a diode across the fuse as shown in Figure 1-2 on page 24.

Please download the Application Note “Understanding Regeneration”from the www.ro- boteq.com for an in-depth discussion of this complex but important topic.

Important Warning

Use the controller only with a rechargeable battery as supply to the Motor Power wires (thick black and red wires).If a transformer or power supply is used,damage to the controller and/or power supply may occur during regeneration.See “Using the Controller with a Power Supply”below for details.

Important Warning

Avoid switching Off or cutting open the main power cables while the motors are spinning.Damage to the controller may occur.Always ground the Power Control wire to turn the controller Off.

Using the Controller with a Power Supply

Using a transformer or a switching power supply is possible but requires special care,

as the current will want to flow back from the motors to the power supply during regen- eration.As discussed in”Power Regeneration Considerations”above,if the supply is

not able to absorb and dissipate regenerated current,the voltage will increase until the

over-voltage protection circuit cuts off the motors.While this process should not be harm- ful to the controller,it may be to the power supply,unless one or more of the protective steps below is taken:

· Use a power supply that will not suffer damage in case a voltage is applied at its output that is higher than its own output voltage.This information is seldom pub- lished in commercial power supplies,so it is not always possible to obtain positive reassurance that the supply will survive such a condition.

30 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

RoboteG

Using the Controller with a Power Supply

Avoid deceleration that is quicker than the natural deceleration due to the friction in the motor assembly (motor,gears,load).Any deceleration that would be quicker than natural friction means that braking energy will need to betaken out of the sys- tem,causing a reverse current flow and voltage rise.

Place a battery in parallel with the power supply output.This will provide a reservoir into which regeneration current can flow.It will also be very helpful for delivering

high current surges during motor acceleration,making it possible to use a lower

current power supply.Batteries mounted in this way should be connected for the

first time only while fully charged and should not be allowed to discharge.The power supply will be required to output unsafe amounts of current if connected directty to a discharged battery.Consider using a decoupling diode on the power supply’s output to prevent battery or regeneration current to flow back into the power supply.

Place a shunt regulator such as Roboteq’s SR5K.This device will monitor the

voltage at the controller and place resistive load in parallel with the power supply in order to absorb the regenerated current.The diagram below shows to wire the SR5K shunt regulator.

Possible Failure Causes

SECTION 2

Safety

Recommendations

In many applications,Roboteq controllers drive high power motors that move parts and

equipment at high speed and/or with very high force.In case of malfunction,potentially

enormous forces can be applied at the wrong time and/or wrong place causing serious

damage to property and/or harm to a person.While Roboteq controllers operate very re- liably,and failures are rare,a failure is possible as with any other electronic equipment.If there is any danger that a loss of motor control can cause damage or injury,you must plan on that possibility and implement methods for stopping the motor independently of the controller operation.

Below is a list of failure categories,their effect and possible ways to regain control,or min- imize the consequences.The list of possible failures is not exhaustive and the suggested prevention methods are provided as examples for information only.

Important Safety Disclaimer

Dangerous uncontrolled motor runaway condition can occur for a number of rea-

sons,including,but not limited to command or feedback wiring failure,configura- tion error,faulty firmware,errors in user MicroBasic script or in the user program,or controller hardware failure.The user must assume that such failures can occur and

must take all measures necessary to make his/her system safe in all conditions.

The information contained in this manual,and in this section in particular,is provid-

ed for information only.Roboteq will not be liable in case of damage or injury as a result of product misuse or failure.

Possible Failure Causes

The dangerous unintended motor operation could occur for a number of reasons,includ- ing,but not limited to:

· Failure in Command device

· Feedback sensors malfunction

· Wiring errors or failure

· Controller configuration error

· Faulty firmware

Safety Recommendations

lRoboteQ

Errors or in user MicroBasic

scripts

·

oversights

· Controller hardware failure

Motor Deactivation in Normal Operation

In normal operation,the controller is always able to tum off the motor if it detects faults or if instructed to do so from an external command.

In case of wiring problem,sensor malfunction,firmware failure or error in user Microbasic scripts,the controller may be in a situation where the motors are turned on and kept on as long as the controller is powered.A number of features discussed throughout this manual are available to stop motor operation in case of an abnormal situation.These include:

· Watchdog on missing incoming serial/USB commands

· Loss detection of Radio Pulse

· Analog command outside the valid range

· Limit switches

· Stall detection

· Close Loop error detection

· Other …

Additional features can easily be added using MicroBasic scripting.

Ultimately,the controller can be simply turned off by grounding the Power Control pin.As- suming there is no hardware damage in the power stage,the controller output will be off (i.e.motor wires floating)when the controller is off.

Important Warning:

While cutting the power to the motors is generally the best thing to do in case of major failure,it may not necessarily result in a safe situation.

Motor Deactivation in Case of Output Stage Hardware Failure

On brushed DC motor controllers,the power stage for each motor is composed of 4 MOSFETs (semiconductor switches).In some cases of MOSFET failures,it is possible that one or both motors will remain permanently powered with no way to stop them either via software or by turning the controller off.

On brushless motor controllers,shorted MOSFETs will not cause the motor to turn on its own.Nevertheless,it is still advised to follow the recommendations included in this section.

The figures below show all the possible combinations of shorted MOSFETs switches in a brushed DC motor controller.

34 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ Motor Deactivation in Case of Output Stage Hardware Failure

FIGURE 2-1.MOSFET Failures resulting in no motor activation

FIGURE 2-2.MOSFET Failures resulting in battery short circuit and no motor activation

FIGURE 2-3.MOSFET Failure resulting in motor activation

Two failure conditions (15 and 16)will result in the motor spinning out of control re- gardless of whether the controller is on or off.While these failure conditions are rare, users must take them into account and provide means to cut all power to the control- ler’s power stage.

On controllers with STO circuitry an extra test is taken place upon power-up or when- ever the STT command is executed (see STT-STO Self-Test,p.205).During this test the FETS are checked whether they are shorted (and so damaged)or not.If either of them is shorted then the MOSFail bit in the fault flags is set,as long as the EStop bit and the FETs Off bit in Status flags.This fault is cleared only when the STT runs again and the MOSFET failure goes away.

Remote Emergency Power Disconnect

In remote controlled systems,the emergency switch must be replaced by a high power contactor relay as shown in Figure 2-6.The relay must be normally open and be activated using an RC switch on a separate radio channel.The receiver should preferably be pow- ered directly from the system’s battery.If powered from the controller’s 5V output,keep in mind that in case of a total failure of the controller,the 5V output may or may not be interrupted.

The receiver must operate in such a way that the contactor relay will be off if the transmit- ter if off or out of range.

The transmitter should have a visible and easy to reach an emergency switch for the op- erator.That switch will be used to deactivate the relay remotely.It could also be used to shutdown entirely the transmitter,assuming it is determined for certain that this will deac- tivate the relay at the controller.

Protection using Supervisory Microcomputer

In applications where the controller is commanded by a PC,a microcomputer or a PLC,

that supervisory system could be used to verify that the controller is still responding and cut the power to the controller’s power stage in case a malfunction is detected.The su- pervisory system would only require a digital output or other means to activate/deactivate the contactor relay as shown in the figure below.

Safe Torque-Off (STO)

The controller must have the Power Control input wired to the battery so that it can oper ate and communicate independently of the power stage.The controller’s processor will then activate the contactor coil through a digital output configured to turn on when the

“No MOSFET Failure”condition is true.The controller will automatically deactivate the

coil if the output is expected to be off and the battery current is above 500mA to 2.5A (de- pending on the controller model)for more than 0.5s.

The contactor must berated high enough so that it can cut the full load current.For even higher safety,additional precaution should betaken to prevent and to detect fused contac- tor blades.

This contactor circuit will only detect and protect against damaged output stage condi-

tions.It will not protect against all other types of fault.Notice therefore,the presence of an emergency switch in series with the contactor coil.This switch should be operated

manually or remotely,as discussed in the Manual Emergency Power Disconnect the Re- mote Emergency Power Disconnect and the Protection using Supervisory Microcomputer earlier in this section of the manual.

Using this contactor circuit,turning off the controller will normally deactivate the digital output and this will cut the power to the controller’s output stage.

Important Warning

Fully autonomous and unsupervised systems cannot depend on electronics alone to ensure absolute safety.While a number of techniques can be used to improve safety, they will minimize but never totally eliminate risks.Such systems must be mechani- cally designed so that no moving parts can ever cause harm in any circumstances.

Safe Torque-Off (STO)

Safe Torque Off is a safe method for switching controller in a state where no torque is

generated,regardless whether the controller is operating normally or is faulty.This func- tion is a mechanism that prevents the drive from restarting unexpectedly.STO has the

immediate effect that the drive cannot supply any torque-generating energy.STO can be used wherever the drive will be brought to a standstill in a sufficiently short time by the

load torque or friction or where coasting down of the drive is not relevant to safety.STO enables safe working and has a wide range of use in motion control systems with moving axes.The advantage of the integrated STO safety function compared with standard safety technology using electromechanical switchgear is the elimination of separate components and the effort that would be required to wire and service them.Because of the rapid elec- tronic switching times,the function has a shorter switching time than the electromechani- cal components in a conventional solution.

Specific motor controllers implement Safe Torque-Off (STO)circuitry,which is certified

from TUV (T-version -Certification No.M6A 1045040001 Rev.01).STO is the most com- mon safety function,meant for motor controllers,ensuring that upon trigger no torque will be generated even after the controller power cycle.For controllers without the specific cir cuit the STO is implemented in firmware alone and digital inputs 1 and 2 are usually used (check controller’s datasheet).

Safety Recommendations lRoboteQ
Safe Torque Off (STO)on Roboteq Controllers

Two digital inputs on the user lO connector can be used to put the controller in a state where the motor is deprived of energy.

The two inputs,labeled STO1 and STO2 must both be brought and maintained at a logic level 1 for the controller to be active.If any one or both of these lines are at 0,the output is de-energized.

The STO circuit operates independently of the MCU.It will always override the MCU,

whether the MCU is processing normally,or is in a hardware of firmware fault condition.

The STO circuit works by controlling the voltage supply to the controller’s MOSFET driv- ers.When both STO1 and STO2 are at logic 1 level,the MOSFET driver are supplied with power.When either or both STO1 and STO2 are at logic level 0,the MOSFET driver power is cut,and the MOFETs gates can no longer be above the ON threshold level,regardless of the MCU activity

Accordingly,the STO circuit is built with redundancy and will continue to function if any one component is faulty,anywhere in the STO circuit or elsewhere in the controller.

Soft-STO inputs

On controllers that do not have the certified STO circuitry,a soft STO implementation is available,which clones the principles of the real STO without of course being certified.

In that case all the available digital inputs have an extra action “Soft STO”Two of them need to have this action activated and they will act as STO inputs.

Activating STO

By factory default STO is disabled.It must be enabled by removing the jumper located on the controller’s PCB.STO is activated by removing power (logic level 0)to both STO in-

puts.In order for controller to monitor STO state,this function must be activated through Roborun+Utility or serial command (check command section).The controller will imme- diately stop generation of torque in the motor.STO functionality is only available in the T version of the controller.

Deactivating STO

STO is deactivated by applying a voltage (logic level 1)to both STO inputs.After this a new start command has to be given to turn the motor.It can be disabled by connecting the

jumper located on the controller’s PCB.After that user should disable the function through Roborun+Utility or serial command (check command section).

Constraints when using STO

· The STO feature is only approved for use with Brushless DC or AC Induction motors. · All voltages attached to the controller need to fulfil SELV or PELV requirements.

· After first installation and at least every 3 months the test as descnibed in chapter 14 has to be conducted.

This failure can have several internal and external reasons.If the failure is shown please check the cabling and the signals to STO 1 and STO 2.Both signals much have at all times the same level.

· Check that the STO jumper is set correctly and STO is configured correctty

· Check wiring

· Check cabling for short circuits or open circuits

If the failure persists,contact Roboteq support.

IMPORTANT WARNING

Same status LED pattern is used for undervoltage and overvoltage faults and that

should not be confusing.If STO fault appear it is normal for the controller voltage to be off and undervoltage fault to trigger.Either way this Status LED pattern indicates a situation that should be treated with caution.

Firmware implementation

The STO circuit will operate regardless of the MCU activity.However,when operating nor mally the MCU will perform the following functions:

1. Self-test that the STO circuits,switches and the power MOSFETs are functional.

This is done every time the controller is powered on.It can also be done at any time using command STT (seeSTT·STO Self-Test,p.205)from the system’s PC or PLC. The self-test can also be initiated by the controller itself using its scnipting language, at periodic time intervals,or any other userdefine rule(s).

lf the self-test fails,the controller will stop driving the MOSFETs and set a fault flag that can be monitored by the PLC/Computer.It can also activate one of its digital

outputs to indicate the fault.

Safety Recommendations

lRoboteQ

2. The STO inputs are monitored continuously every 1ms.If one or both STO inputs are at level zero and the MOSFET driver supply voltage has not dropped,an STO fault is detect- ed.The STO fault flag is set.A user digital output can be activated to indicate the fault.

Installation -Maintenance

The STO circuit needs to be tested before first installation and at least every 3 months according to the below sequence:

1. Activate STO (both logic level O)

2. Check that STO is active (through Roborun+Utility/Serial)

3. Check that there is no STO fault present (through Roborun+Utility/Serial)

4. Deactivate STO 1 and STO 2 (both logic level 1)

5. Check that STO is not active and that there is no STO fault present (through Robo- run+Utility/Seriall.

SAFETY INSTALLATION

It is required that the controller has to be placed in an enclosure that can provide IP54 protection.

SAFETY REGISTRATION

It is required that STO end user should follow up www.roboteq.com and register to site/forum for any news about safety function.

STO Voltage source specification attention

In order to have maximum response at STO implementation,user/installer/integrator

should use voltage source with low output capacitance.In any other case,latency in acti- vation might occur.

This section describes the various inputs and outputs and provides guidance on how to connect sensors,actuators or other accessories to them.

Controller Connections

The controller uses a set of power connections DSub and plastic connectors for all neces- sary connections.

The power connections are used for connecting to the batteries and motor,and will typ- ically carry large current loads.Details on the controller’s power wiring can be found at “Connecting Power and Motors to the Controller”section of this manual.

The DSub and plastic connectors are used for all low-voltage,lowcurrent connections to the Radio,Microcontroller,sensors,and accessories.This section covers only the connec- tions to sensors and actuators.

For information on how to connect the RS232 or the RS485 ports,see “Serial (RS232/ RS485/TCP/USB)Operation”section.

The remainder of this section describeshow to connect sensors and actuators to the con- troller’s low-voltage l/O pins that are located on the DSub and plastic connectors.

Controller’s Inputs and Outputs

The controller includes several inputs and outputs for various sensors and actuators.De- pending on the selected operating mode,some of these VOs provide command,feedback and/or safety information to the controller.

When the controller operates in modes that do not use these l/Os,these signals are ig- nored or can become available via the RS232/RS485/TCP/USB port for user application. Below is a summary of the available signals and the modes in which they are used by the controller.The actual number of the signal of each type,voltage or current specification, and their position on the l/O connector is given in the controller datasheet.

Connecting devices to Digital Outputs

Connecting devices to Digital Outputs

Depending on the controller model,2 to 8 Digital Outputs are available for multiple pur- poses.The Outputs are Open Drain MOSFET outputs capable of driving over 1A at up to 24V.See datasheet for detailed specifications.

Since the outputs are Open Drain,the output will be pulled to ground when activated. The load must therefore be connected to the output at one end and to a positive voltage source (e.g.a 24V battery)at the other.

Connecting Resistive Loads to Outputs

Resistive or other non-inductive loads can be connected simply as shown in the diagram below.

Important Warning

Overvoltage spikes induced by switching inductive loads,such as solenoids or re- lays,will destroy the transistor unless a protection diode is used.

Connecting Switches or Devices to Inputs shared with Outputs

On HDCowx and HBLxoxxx controllers,Digital inputs DIN12 to DIN19 share the connector pins with digital outputs DOUT1 to DOUT8.When the digital outputs are in the Off state,these out- puts can be used as inputs to read the presence or absence of a voltage at these pins.

FIGURE 3-3.Switch wiring to inputs shared with outputs

For better noise immunity,an external pull up resistor should be installed even though one is already present inside the controller.

Important Warning

Do not activate an output when it is used as input.If the input is connected directly to a positive voltage when the output is activated,a short circuit will occur.Always pull the input up via a resistor.

Connecting Switches or Devices to direct Digital Inputs

The controller Digital Inputs are high impedance lines with a pull down resistor built into the controller.Therefore it will report an Off state if unconnected,A simple switch as

shown in Figure 3-4 can be used to activate it.When a pull up switch is used,for better noise immunity,an external pull down resistor should be installed even though one is al ready present inside the controller.

Important Notice

On newer motor controllers models,activating the pulse mode on input will also enable a pull up resistor on that input.If the input is also used for analog capture, the analog reading will be wrong.Make sure the pulse mode is disabled on that

input.

Reducing noise on Analog Inputs

The Analog inputs are very fast and have a high input resistance.They will therefore eas- ily be disturbed by ambient electrical noise and this will cause the analog reading to be

fluctuating.Use shielded cables between the input and the analog sensor.Add a 1uF ca- pacitor between the input pin and the GND pin.With good shielding and filtering,a signal stable to withing +/-5V or better can generally be achieved.

Connecting Potentiometers to Analog Inputs

Potentiometers mounted on a foot pedal or inside a joystick are an effective method for giving the command to the controller.In closed loop mode,a potentiometer is typically used to provide position feedback information to the controller.

Connecting the potentiometer to the controller is as simple as shown in the diagram in Figure 3-9.

The potentiometer value is limited at the low end by the current that will flow through it and which should ideally not exceed 5 or 10mA.If the potentiometer value is too high,

the analog voltage at the pot’s middle point will be distorted by the input’s resistance to ground of 53K.A high value potentiometer also makes the input sensitive to noise,partic- ularly if wiring is long.Potentiometers of 1K or 5K are recommended values.

Because the voltage at the potentiometer output is related to the actual voltage at the

controller’s 5V output,configure the analog input in “Relative Mode”This mode measures the actual voltage at the 5V output in order to eliminate any imprecision due to source

voltage variations.Configure using the PC Utility.

Connecting Potentiometers for Commands with Safety band guards

When a potentiometer is used for sensing a critical command (Speed or Brake,for exam- ple)it is critically important that the controller reverts to a safe condition in case wiring is sectioned.This can be done by adding resistors at each end of the potentiometer so that the full OV or the full 5V will never be present,during normal operation,when the potenti- ometer is moved end to end.

Using this circuit shown below,the Analog input will be pulled to OV if the two top wires of the pot are cut,and pulled to 5V if the bottom wire is cut.In normal operation,using the shown resistor values,the analog voltage at the input will vary from 0.2V to 4.8V.

220 Ohm Ground

FIGURE 3-10.Potentiometer wiring in Position mode

Connecting Sensors and Actuators to Input/Outputs RoboteQ
The controller’s analog channels are configured by default so that the min and max com- mand range is from 0.25V to 4.75V.These values can be changed using the PC configura- tion utility.This ensures that the full travel of the pot is used to generate a command that spans from full min to full max.

If the Min/Max safety is enabled for the selected analog input,the command will be con- sidered invalid if the voltage is lower than 0.1V or higher than 4.9.These values cannot be changed.

Connecting Tachometer to Analog Inputs

When operating in closed loop speed mode,tachometers can be connected to the con-

troller to report the measured motor speed.The tachometer can be a good quality brushed DC motor used as a generator.The tachometer shaft must be directly tied to that of the

motor with the least possible slack.

Since the controller only accepts a 0 to 5V positive voltage as its input,the circuit shown in Figure 3-11 must be used between the controller and the tachometer:a 10kOhm poten- tiometer is used to scale the tachometer output voltage to -2.5V (max reverse speed)and +2.5V (max forward speed).The two 1kOhm resistors form a voltage divider that sets the idle voltage at mid-point (2.5V),which is interpreted as the zero position by the controller.

With this circuitry,the controller will see 2.5V at its input when the tachometer is stopped,OV when running in full reverse,and +5V in full forward.

The tachometers can generate voltages in excess of 2.5 volts at full speed.It is important, therefore,to set the potentiometer to the minimum value (cursor all the way down per

this drawing)during the first installation.

Since in closed loop control the measured speed is the basis for the controller’s power output (i.e.deliver more power if slower than the desired speed,less if higher),an ad-

justment and calibration phase is necessary.This procedure is described in “Closed Loop Speed Mode”section of this manual.

IRoboteQ Connecting External Thermistor to Analog Inputs

Important Warning

The tachometer’s polarity must be such that a positive voltage is generated to the controller’s input when the motor is rotating in the forward direction.If the polarity is inverted,this will cause the motor to run away to the maximum speed as soon

as the controller is powered and eventually trigger the closed loop error and stop. lfthis protection is disabled,there will be no way of stopping it other than pressing the emergency stop button or disconnecting the power.

Connecting External Thermistor to Analog Inputs

Using external thermistors,the controller can be made to supervise the motor’s tempera- ture and cut the power output in case of overheating.Connecting thermistors is done ac- cording to the diagram shown in Figure 3-12.Use a 10kOhm Negative Coefficient Therm- istor (NTC)with the temperature/resistance characteristics shown in the table below.

Thermistors are non-inear devices.Using the circuit described in Figure 3-12,the controller will read the following values according to the temperature.For best precision,the analog input must be configured to read in Relative Mode.

The analog input must be configured so that the minimum range voltage matches the

desired temperature and that action be triggered when that limit is reached.For example 500mV for 80oC,according to the table.The action can be any of the actions in the list.

sors,configure the pulse input in Duty Cycle mode.Beware that the sensor should always be pulsing and never output a steady DC voltage at itsends.The absence of pulses is con- sidered by the controller as a loss of signal.

Connecting SSl Sensors

SSI Sensors Overview

SSI sensors are absolute encoders that send their data using Synchronous Serial Interface (SSI).Using SSl protocol offers reduced wiring and EMI immunity.SSl sensors as abso-

lute encoders they report a signal respective to the shaft position and can be used in both multi-turn and single-turn applications.Roboteq controllers support the use of SSl sensors with resolution up to 16 bits.

Optical Incremental Encoders Overview

Optical incremental encoders are a means for capturing speed and traveled distance on a motor.Unlike absolute encoders which give out a multi-bit number (depending on the res- olution),incremental encoders output pulses as they rotate.Counting the pulses tells the application how many revolutions,or fractions of,the motor has turned.Rotation velocity can be determined from the time interval between pulses or by the number of pulses

within a given time period.Because they are digital devices,incremental encoders will measure distance and speed with perfect accuracy.

Since motors can move in forward and reverse directions,it is necessary to differentiate the manner that pulses are counted so that they can increment or decrement a position counter in the application.Quadrature encoders have dual channels,A and B,which are electrically phased 90°apart.Thus,the direction of rotation can be determined by monitor ing the phase relationship between the two channels.In addition,with a dua-channel en- coder,a four-time multiplication of resolution is achieved by counting the rising and falling edges of each channel (A and B).For example,an encoder that produces 250 Pulses per Revolution (PPR)can generate 1,000 Counts per Revolution (CPR)after quadrature.

IRoboteQ

Connecting Optical Encoders

The figure below shows the typical construction of a quadrature encoder.As the disk ro- tates in front of the stationary mask,it shutters light from the LED.The light that passes through the mask is received by the photodetectors.Two photodetectors are placed side by side at so that the light making it through the mask hits one detector after the other to produces the 90°phased pulses.

FIGURE 3-18.Typical quadrature encoder construction

Unlike absolute encoders,incremental encoders have no retention of absolute position upon power loss.When used in positioning applications,the controller must move the motor until a limit switch is reached.This position is then used as the zero references for all subsequent moves.

Recommended Encoder Types

The module may be used with most incremental encoder modules as long as they include the following features:

· Two quadrature outputs (Ch A,Ch B),single ended

· 3.0V minimum swing between 0 Level and 1 Level on quadrature output

· 5VDC operation.50mA or less current consumption per encoder

More sophisticated incremental encoders with index and other features may be used, however these additional capabilities will be ignored.

The choice of encoder resolution is very wide and is constrained by the module’s maxi- mum pulse count at the high end and measurement resolution for speed at the low end.

Specifically,the controller’s encoder intertace can process 1 million counts per second, unless otherwise specified in the product datasheet.

Commercial encoders are rated by their numbers of “Pulses per Revolution”(also some- times referred to as “Number of Lines”or “Cycles per Revolution”).Carefully read the

manufacturer’s datasheet to understand whether this number represents the number of pulses that are output by each channel during the course of a 360 degrees revolution rath- er than the total number of transitions on both channels during a 360 degrees revolution. The second number is 4 times larger than the first one.

The formula below gives the pulse frequency at a given RPM and encoder resolution in Pulses per Revolution.

Pulse Frequency in counts per second =RPM/60*PPR*4

Connecting Sensors and Actuators to Input/Outputs IRoboteQ
Example:a motor spinning at 10,000 RPM max,with an encoder with 200 Pulses per Rev- olution would generate:

10,000/60*200*4=133.3 kHz which is well within the 1MHz maximum supported by the encoder input.

An encoder with 200 Pulses per Revolutions is a good choice for most applications.

A higher resolution will cause the counter to count faster than necessary and possibly reach the controller’s maximum frequency limit.

An encoder with a much lower resolution will cause speed to be measured with less precision.

Connecting the Encoder

Encoders connect directly to pins present on the controller’s connector.The connector provides 5V power to the encoders and has inputs for the two quadrature signals from each encoder.The figure below shows the connection to the encoder.

For several controller models,the Encoder inputs are by default mapped in Molex connec- tor.In order to be able to use encoders and SSl sensors at the same time (see “MLX”in the command reference section),the encoders can be mapped to DB25 connector pins where pulse inputs are.

Cable Length and Noise Considerations

The cable should not exceed one 3′(one meter)to avoid electrical noise to be captured by the wiring.A ferrite core filter should be inserted near the controller for length beyond 2′(60 cm).For longer cable length use an oscilloscope to verify signal integrity on each of the pulse channels and on the power supply.

FIGURE 3-20.Use ferrite core on cable length beyond 2’or 60cm

Important Warning

Excessive cable length will cause electrical noise to be captured by the controller

and cause erratic functioning that may lead to failure.In such a situation,stop oper ation immediately.

Motor -Encoder Polarity Matching

When using encoders for closed loop speed or position control,it is imperative that when the motor is turning in the forward direction,the counter increments its value and a posi- tive speed value is measured.The counter value can be viewed using the PC utility.

If the Encoder counts backward when the motor moves forward,correct this by either:

1-Swapping Channel A and Channel B on the encoder connector.This will cause the en- coder module to reverse the count direction,

2-Enter a negative number in the PPR configuration will also cause the counter to count in the reverse direction

3-Swapping the leads on the motor.This will cause the motor to rotate in the opposite direction.

Basic Operation

SECTION 4

VO Configuration

and Operation

This section discusses the controller’s digital and analog inputs and output and how they can be used.

Basic Operation

The controller’s operation can be summarized as follows:

· Receive commands from a radio receiver,joystick or a microcomputer

·Activate the motor according to the received command

· Perform continuous check of fault conditions and adjust actions accordingly

· Report real-time operating data

The diagram below shows a simplified representation of the controller’s internal operation. The most noticeable feature is that the controller’s serial,digital,analog,pulse,and encod- er inputs may be used for practically any purpose.

Safety Recommendations

RoboteQ

Practically all operating configurations and parameters can be changed by the user to meet any specific requirement.This unique architecture leads to a very high number of possibilities.This section of the manual describes all the possible operating options.

Input Selection

As seen earlier in the controller’s simplified internal operating diagram on Figure 4-1,any input can be used for practically any purpose.All inputs,even when they are sharing the same pins on the connector,are captured and evaluated by the controller.Whether input is used,and what it is used for,is set individually using the descriptions that follow.

Important Notice

On shared l/O pins,there is nothing stopping one input to be used as analog or

pulse at the same time or for two separate inputs to act identically or in conflict

with one another.While such an occurrence is normally harmless,it may cause the controller to behave in an unexpected manner and/or cause the motors not to run. Care must be exercised in the configuration process to avoid possible redundant or conflictual use.

Digital Inputs Configurations and Uses

Each of the controller’s digital Inputs can be configured so that they are active high or ac- tive low.Each output can also be configured to activate one of the actions from the list in the table below.In multi-channel controller models,the action can be set to apply to any or all motor channels.

Analog Inputs Configurations and Use

Configuring the Digital Inputs and the Action to use can be done very simply using the PC Utility.

Wiring instructions for the Digital Inputs can be found in “Connecting Switches or Devices to inputs shared with Outputs”onpage 44

Analog Inputs Configurations and Use

The controller can do extensive conditioning on the analog inputs and assign them to a different use.

Each input can be disabled or enabled.When enabled,it is possible to select the whether

capture must be an absolute voltage or relative to the controller’s 5V Output.Details on how to wire analog inputs and the differences between the Absolute and Relative captures can be found in “Using the Analog Inputs to Monitor External Voltages”page 50.

TABLE 4-2.Analog Capture Modes

Analog Capture Mode Description
Disabled Analog capture is ignored (forced to O)
Absolute Analog capture measures real volts at the input
Relative Analog captured is measured relative to the 5V Output which is typically around 4.8V to 5.1V depending on the controller model and the load. Correction is applied so that an input voltage measured to be the same as the 5V Output voltage is reported at 5.0V

The raw Analog capture then goes through a series of processing shown in the diagram below.

See the list and description in Table 4.1,”Digital Input Action List”on page 58.

Analog Min/Max Detection

An analog input can be configured so that an action is triggered if the captured value is

above a userdefined Maximum value and/or under a userdefined Minimum value.The ac-

tions that can be selected are the same as these that can be triggered by the Digital Input.

Min,Max and Center adjustment

The raw analog capture is then scaled into a number ranging from-1000 to +1000 based on use-defined Minimum,Maximum and Center values for the input.For example,setting the minimum to 500mV,the center to 2000mV,and the maximum to 4500mV,will pro-

duce the output to change in relation to the input as shown in the graph below

Output

FIGURE 4-3.Analog Input processing chain

This feature allows capturing command or feedback values that match the available range of the input sensor (typically a potentiometer).

For example,this capability is useful for modifying the active joystick travel area.The figure below shows a transmitter whose joystick’s center position has been moved back so that the operator has a finer control of the speed in the forward direction than in the reverse position.

FIGURE 4-4.Calibration example where more travel is dedicated to forward motion

64 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Analog Inputs Configurations and Use

Setting the center value to be the same as the min value makes the input capture only commands in a positive direction.For example if Min =Center =200 and Max =4500, the input will convert into O when 200 and below,and 1000 above 4500.

The Min,Max,and Center values are defined individually for each input.They can be easily entered manually using the Roborun PC Utility.The Utility also features an Auto-calibration function for automatically capturing these values.

Deadband Selection

The adjusted analog value is then adjusted with the addition of a deadband.This parameter

selects the range of movement change near the center that should be considered as a 0

command.This value is a percentage from 0 to 50%and is useful,for example,to allow some movement of a joystick around its center position before any power is applied to a motor.The graph below shows output vs input changes with a deadband of approximately 40%.

Output

FIGURE 4-5.Effect of deadband on the output

Note that the deadband only affects the start position at which the joystick begins to take effect.The motor will still reach 100%when the joystick is in its full position.An illustration of the effect of the deadband on the joystick action is shown in Figure 4-6 below.

Deadband

Position

FIGURE 4-6.Effect of deadband on joystick position vs.motor command

The deadband value is set independently for each input using the PC configuration utility.

lRoboteQ

Command Correction

An optional exponential or a logarithmic adjustment can then be applied to the signal.The exponential correction will make the commands change less at the beginning and become stronger at the end of the joystick movement.The logarithmic correction will have a stron- ger effect near the start and lesser effect near the end.The linear selection causes no

change to the input.There are 3 exponential and 3 logarithmic choices:weak,medium and strong.The graph below shows the output vs input change with exponential,logarithmic and linear corrections.

Output

FIGURE 4-7.Effect of exponential /logarithmic correction on the output

The exponential or log correction is selected separately for each input using the PC Con- figuration Utility.

Use of Analog Input

After the analog input has been fully processed,it can be used as a motor command or, if the controller is configured to operate in a closed loop,as a feedback value (typically speed or position).

Each input can therefore be configured to be used as command or feedback for any motor channel(s).The mode and channel(s)to which the analog input applies are selected using the PC Configuration Utility.

Pulse Inputs Configurations and Uses

The controller’s Pulse Inputs can be used to capture pulsing signals of different types.

Digital Outputs Configurations and Triggers

The controller’s digital outputs can individually be mapped to turn On or Off based on the status of user-selectable internal status or events.The table below lists the possible as- signment for each available Digital Output.

Configuring the encoder parameters is done easily using the PC Configuration Utility.

SSl Configuration and Use

On controller models equipped with SSl sensor inputs,SSl sensors enable a range of pre- cision motion control features.See “Connecting SSl Sensors”page 51 for a detailed dis- cussion on how SSl sensors work and how to physically connect them to the controller.

FIGUER 4-10.SSI Sensor input processing

The SSl sensor’s signal is processed to generate up and down counts depending on the

rotation direction.The counts are then summed inside a 32-bit counter.The counter can

be read directty using serial commands and/or can be used as a position feedback source

for the closed loop position mode.

Also taking into consideration that SSl sensors are absolute sensors,the sensor can be configured in order to indicate the absolute position of the rotor shaft (Absolute Feed- back).In that case,the counter holds the absolute position of the rotor shaft.

The count information is also used to measure rotation speed.Using the SSl Sensor Res- olution (which represent the counts per revolution,SCPR)configuration parameter,the output is a speed measurement in actual RPM that is useful in closed loop speed modes where the desired speed is set as a numerical value,in RPM,using a serial command.

Configuring the SSI Sensor parameters is done easily using the PC Configuration Utility.

engaged.

Hall and other Rotor Sensor Inputs

On brushless motor controllers,the Hall or other Rotor position sensor that is used to switch power around the motor windings,are also used to measure speed and distance traveled.

Speed is evaluated by measuring the time between transition of the Hall Sensors.A 32 bit up/down counter is also updated at each Hall Sensor transition.

Speed information picked up from the Hall Sensors can be used for closed loop speed op- eration without any additional hardware.

Sensor Min Max values

Each Encoder counter,SSI Sensor Counter or Internal Sensor Counter counter can be

compared to the respective userdefined Min and/or Max values and trigger an action if these limits are reached.The type actions are the same as these selectable for Digital In- puts and described in “Digital inputs Configurations and Use”page 58.

Relative Speed

The speed information is also scaled to produce a number ranging from -1000 to +1000

relative to a userconfigured arbitrary Max RPM value.For example,with the Max RPM

configured as 3000 and the motor rotating at 1500 RPM,the measured relative speed will be 500.Relative speed is useful for closed loop speed mode that uses Analog or Pulse

inputs as speed commands.

Brake Release

Each digital output can be connected to a brake solenoid and control it based on the re-

spective configuration (Motor is on action).In that case when there is a non-idle motor

command the DOUT is activated and the brake is released.When the motor command

becomes idle and the motor stops moving,then the DOUT is deactivated and the brake is

A delay time has been introduced for the brake engage.It is a delay between the time a motor stops and the time an output connected to a brake solenoid will be released (for more details see BKD-Brake activation delay in ms, in page 301).

In some boards the PWM brake feature has been implemented.In these cases there

are special 2 pin brake outputs(Brk+,Brk-),which can be modulated with PWM so that a higher voltage can be initially applied to energize the coil (for more details see BRV

-Brake Release Voltage, in page 331),and then reduced (for more details see BHV –

Brake Hold Voltage, in page 332)to maintain the brake released while consuming less energy.Final there is also a configurable time value,which represents for how much time the Brake Release voltage will be applied (for more details see BDT-Brake Delay Time, in page 332).

Accessing Sensor Information

Once enabled,the pulses are sent continuously by the sensor 100 times per second.The pulses are captured and parsed by the motor controller as they arrive.A realtime mirror image of sensor data is then present inside the controller.From there the sensor informa- tion can be read using serial,USB,CAN or MicroBasic scripts like any other of the control- ler’s operational parameters.

The following Motor Controller queries are available for reading the captured sensor data.

Connecting Multiple Similar Sensors

More than one similar sensors can be connected to a single motor controller.For Magnet- ic sensors,this can be useful in AGV designs that must be able to move in the forward

Connecting Multiple Similar Sensors

Accessing Multiple Sensor Information Sequentially

Two methods are available for accessing each sensor’s data when multiple sensors are connected.

The first method is to only have one sensor enabled at any one time.This is done by en- abling and disabling pulse inputs via serial commands or MicroBasic scripting.Examples:

^PMOD 10:Serial command to Disable Sensor on pulse input 1

SetconfigLPMOD,1,0):Microbasic instruction to disable sensor on Pulse input 1

APMOD 24:Enable Sensor on Pulse input 2

SetconfigLPMOD,2,4):Microbasic instruction to enable sensor on Pulse input 2

The sensor information can then be accessed with the respective queries as discussed above (?MGD,?MGT,?MGM,?FLW.

Accessing Multiple Sensor Information Simultaneously

It is possible to have all sensors enabled at the same time by having theirrespective pulse input configured accordingly.

When more than one pulse input is configured that way,the sensor data is accessible

using the ?MGD,?MGT,?MGM,?MGY or ?FLW queries as follows,where x is the pulse input number (1,2,3 etc.).

Input Command Modes and Priorities

SECTION 6

Command

Modes

This section discusses the controller’s normal operation in all its supported operating modes.

input Command Modes and Priorities

The controller will accept commands from one of the following sources

· Serial data (RS232,RS485,TCP,USB)

· Pulse (R/C radio,PWM,Frequencyl

·Analog signal (0 to 5V)

· Spektrum Radio (on selected models)

· CAN Intertace

· Microbasic Script

One,many or all command modes can be enabled at the same time.When multiple

modes are enabled,the controller will select which mode to use based on a user select- able priority scheme and the hardcoded priorities concening the CAN interface and the Microbasic script.Setting the priorities is done using the PC configuration utility.

This scheme uses a priority table containing three parameters and let you select which

mode must be used in each priority order.During operation,the controller reads the first priority parameter and switches to that command mode.If that command mode is found to be active,that command is then used.If no valid command is detected,the controller switches to the mode defined in the next priority parameter.If no valid command is recog- nized in that mode,the controller then repeats the operation with the third priority param- eter.If no valid command is recognized in that last mode,the controller applies a default command value that can be set by the user (typically 0).

Brushless Motor Connections and Operation

lRoboteQ

FIGURE 6-1.Controller’s possible command modes

In the Serial mode,the mode is considered as active if commands

· !G-Go to Speed or to Relative Position

· !MS-Stop in all modes

· !S-Set Motor Speed

· !TC-Target Torque

· !GlQ-SetTorque Amps

· !GID-Set Flux Amps

arrive within the watchdog timeout period via the RS232,RS485,TCP or USB ports.The

mode will be considered inactive,and the next lower priority level will be selected as soon as the watchdog timer expires.Note that disabling the watchdog will cause the serial

mode to be always active after the first command is received,and the controller will never switch to a lower priority mode.

If the abovementioned commands are called from a script then the Script mode is en- abled and if they are called from CAN network the CAN mode is enabled.

In the pulse mode,the mode is considered active if a valid pulse train is found and re- mains present.

In analog mode,the mode is considered active at all time,unless the Center at Start safety is enabled.In this case,the Analog mode will activate only after the joystick has been cen- tered.The Keep within Min/Max safety mode will also cause the analog mode to become

inactive,and thus enable the next lower priority mode,if the input is outside of a safe range.

The example in Figure 6-1 shows the controller connected to a microcomputer,a RC ra- dio,and an analog joystick.If the priority registers are set as in the configuration below:

1-Serial

2-Pulse

3-Analog

then the active command at any given time is given in the table below.

will only arbitrate and use Serial or RC Pulse commands.

USB vs Serial Communication Arbitration

Commands may arrive through the RS232,RS485,TCP or the USB port at the same time.They are executed as they arrive in a first come first served manner.Commands that are arriving via USB are replied on USB.Commands arriving via the RS232 are re- plied on the RS232 and so on.Redirection symbol for redirecting outputs to the other port exists (e.g.a command can be made to respond on USB even though it arrived on RS232).

CAN Commands Arbitration

On controllers fitted with a CAN interface,commands received via CAN are processed as they arrive regardless if any other mode,apart from Script mode,is active at the same time.CAN mode has the highest priority from all other modes apart from script mode.

Commands issued from MicroBasic scripts

When sending a Motor command from a MicroBasic script,it will be interpreted by the controller with higher priority than any other interface.If a serial command is received from the seria/USB port at the same time a command is sent from the script,the script command will prevail.

Important Warning

Script and CAN commands are also subject to the serial Watchdog timer.Script

commands have the highest priority and CAN commands similar priority to serial commands.as shown below:

Operating the Controller in RC mode

The controller can be directly connected to an R/C receiver.In this mode,the speed or posi- tion information is contained in pulses whose width varies proportionally with the joysticks’ positions.The controller mode is compatible with all popular brands of RC transmitters.

The RC mode provides the simplest method for remotely controlling a robotic vehicle:little else is required other than connecting the controller to the RC receiver and powering it On.

FIGURE 6-2.R/C radio control mode

The speed or position information is communicated to the controller by the width of a pulse from the RC receiver:a pulse width of 1.0 millisecond indicates the minimum joy- stick position and 2.0 milliseconds indicates the maximum joystick position.When the joystick is in the center position,the pulse should be 1.5ms.

FIGURE 6-3.Joystick position vs.pulse duration default values

The controller has a very accurate pulse capture input and is capable of detecting changes in joystick position (and therefore pulse width)as small as 0.1%.This res- olution is superior to the one usually found in most low cost RC transmitters.The controller will therefore be able to take advantage of the better precision and better

control available from a higher quality RC radio,although it will work fine with lesser expensive radios as well.

Input RC Channel Selection

The controllers feature several inputs that can be used for pulse capture.See product

datasheet for an actual number of pulse input.Any RC input can be used as a command for any motor channels.The controller’s factory default defines two channels for RC

capture lone input on single channel products).Which channel and which pin on the input connector depends on the controller model and can be found in the controller’s datasheet.

Changing the input assignment is done using the PC Configuration utility.

Input RC Channel Configuration

Internally,the measured pulse width is compared to the reference minimum,center,and maximum pulse width values.From this is generated a command number ranging from

-1000(when the joystick is in the min.postion),to O when the joystick is in the center po- sition)to+1000 (when the joystick is in the max position).This number is then used to set the motor’desired speed or position that the controller will then attempt to reach.

For best results,reliability,and safety,the controller will also perform a series of correc- tions,adjustments and checks to the R/C commands,as described below.

Joystick Range Calibration

The Joystick min,max,and center position are adjustable.For best control accuracy,the controller can be calibrated to capture and use your radio’s specific timing characteristics and store them into its internal Flash memory.This is done using a simple calibration pro- cedure described page 64.

Deadband Insertion

The controller allows for a selectable amount of joystick movement to take place around the center position before activating the motors.See the full description of this feature at “Deadband Selection“page 65

Command Correction

The controller can also be set to translate the joystick motor commands so that the motor responds differently depending on whether the joystick is near the center or near the

extremes.Five different exponential or logarithmic translation curves may be applied.

Since this feature applies to the R/C,Analog and RS232 modes,it is described in detail in “Command Correction”page 66,in the General Operation section of the manual.

Reception Watchdog

Immediately after it is powered on,if in the R/C mode,the controller is ready to receive pulses from the RC radio.

If valid pulses are received on any of the enabled Pulse input channels,the controller will consider the RC Pulse mode as active.If no higher priority command is currently active (See”Input Command Modes and Priorities”page 73),the captured RC pulses will serve to activate the motors.

Brushless Motor Connections and Operation RoboteQ
If no valid RC pulses reach the controller for more than 500ms,the controller no lon- ger considers it is in the RC mode and a lower priority command type will be accepted if present.

Important Warning

Some receivers include their own supervision of the radio signals and will move

their servo outputs to a safe position in case of signal loss.Using these types of receiver,the controller will always be receiving pulses even with the transmitter off.

Using Sensors with PWM Outputs for Commands

The controller’s Pulse inputs can be used with various types of angular sensors that use contactless Hall technology and that output a PWM signal.These type of sensors are increasingly used inside joysticks and will perform much more reliably,and typically with higher precision than traditional potentiometers.

The pulse shape output from these devices varies widely from one sensor model to an- other and is typically different from this of RC radios:

-They have a higher repeat rate,up to a couple of kHz.

-The min and max pulse width can reach the full period of the pulse

Care must therefore be exercised when selecting a sensor.The controller will accommo- date any pulsing sensor as long as the pulsing frequency does not exceed 250Hz.The

sensor should not have pulses that become too narrow-or disappear altogether -at the extremes of their travel.Select sensors with a minimum pulse width of 10us or higher. Alternatively,limit mechanically the travel of the sensor to keep the minimum pulse width within the acceptable range.

A minimum of pulsing must always be present.Without it,the signal will be considered as invalid and lost.

Pulses from PWM sensors can be applied to any Pulse input on the controller’s connector. Configure the input capture as Pulse or Duty Cycle.

A Pulse mode capture measures the On time of the pulse,regardless of the pulse period.

A Duty Cycle mode capture measures the On time of the pulse relative to the entire pulse period.This mode is typically more precise as it compensates for the frequency drfts o

the PWM oscillator.

PWM signals are then processed exactty the same way as RC pulses.Refer to the RC pulse paragraphs above for reference.

Operating the Controller In Analog Mode

Analog Command is the simplest and most common method when the controller is used in a non-remote,human-operated system,such as Electric Vehicles.

84 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Operating the Controller In Analog Mode

Input Analog Channel Selection

The controller features 4 to 11 inputs,depending on the model type,that can be used for analog capture.Using different configuration parameters,any Analog input can be used as command for any motor channel.The controller’s factory default defines two channels as Analog command inputs.Which channel and which pin on the input connector depends on the controller model and can be found in the controller’s datasheet.

Changing the input assignment is done using the PC Configuration utility.See “Analog In- puts Configurations and Use”on page 59.

Input Analog Channel Configuration

An Analog input can be Enabled or Disabled.When enabled,it can be configured to cap- ture absolute voltage or voltage relative to the 5V output that is present on the connector. See “Analog Inputs Configurations and Use”on page 59

Analog Range Calibration

If the joystick movement does not reach full OV and 5V,and/or if the joystick center point does not exactly output 2.5V,the analog inputs can be calibrated to compensate for this. See”Min,Max and Center adjustment”on page 60 and “Deadband Selection”on page 61.

Using Digital Input for Inverting direction

Any digital input can be configured to change the motor direction when activated.See

“Digital Inputs Configurations and Uses”on page 58.Inverting the direction has the same effect as instantty moving the command potentiometer to the same level the opposite

direction.The motor will first return to O at the configured deceleration rate and go to the inverted speed using the configured acceleration rate.

Safe Start in Analog Mode

By default,the controller is configured so that in Analog command mode,no motor will start until all command joysticks are centered.The center position is the one where the input equals the configured Center voltage plus the deadband.

After that,the controller will respond to changes to the analog input.The safe start check is not performed again until power is turned off.

Protecting against Loss of Command Device

By default,the controller is protected against the accidental loss of connection to the

command potentiometer.This is achieved by adding resistors in series with the potenti- ometer that reduces the range to a bit less than the full OV to 5V swing.If one or more

wires to the potentiometer are cut,the voltage will actually reach OV and 5V and be con- sidered a fault condition,if that protection is enabled.See “Connecting Potentiometers for Commands with Safety band guards”on page 49.

Brushless Motor Connections and Operation RoboteQ
Safety Switches

Any Digital input can be used to add switch-activated protection features.For example,

the motorls)can be made to activate only if a key switch is tumed On,and a passenger is present on the driver’s seat.This is done using by configuring the controller’s Digital in- puts.See”Digital Inputs Configurations and Uses”page 58.

Monitoring and Telemetry in RC or Analog Modes

The controller can be fully monitored while it is operating in RC or Analog modes.If direct- ly connected to a PC via RS232,RS485,TCP or USB,the controller will respond to oper- ating queries (Amps,Volts,Temperature,Power Out,.…)without this having any effect on its response to Analog or RC commands.The PC Utility can therefore be used to visualize in realtime all operating parameters as the controller runs.See “Run Tab”in Roborun+

Utility User Manual.

In case the controller is not connected via a bi-directional link,and can only send infor

mation one-way,typically to a remote host,the controller can be configured to output a userselectable set of operating parameters,at a user selectable repeat rate.See“Query History Commands”on page 251

MicroBasic scripting can also be used to generate a periodic text string containing param- eters to monitor.

Using the Controller with a Spektrum Satellite Receiver

Some controller models can be connected directly to a miniature Spektrum SP9545 satellite receiver.Using only 3 wires this interface will carry the information of up to 6 command joysticks with a resolution and precision that is significantly higher than traditional 1.5ms pulse signals.

The PC utility is used to map any of the 6 channels as a command for each motor.Binding the receiver to the transmitter is done using the %BIND maintenance command.See

“Maintenance Commands”on page 254 for details on the binding procedure.

Using the Controller in Serial (USB/RS232/RS485/TCP)Mode

The serial mode allows full control over the controller’s entire functionality.The controller will respond to a large set of commands.These are described in detail in”Serial (RS232/ RS485/USB/TCP)Operation”on page 161.

Motor Operating

Features and

Options

This section discusses the controller’s operating features and options relating to its motor outputs.

Power Output Circuit Operation

The controller’s power stage is composed of high-current MOSFET transistors that are

rapidly pulsed on and offusing Pulse Width Modulation (PWM)technique in order to deliv- er more or less power to the motors.The PWM ratio that is applied is the result of a com- putation that combines the user command and safety related corrections.In closed-oop operation,the command and feedback are processed together to produce the adjusted

motor command.The diagram below gives a simplified representation of the controller’s operation.

Motor Operating Features and Options lRoboteQ
Global Power Configuration Parameters

PWM Frequency

The power MOSFETs are switched at 16kHz.

Overvoltage Protection

The controller includes a battery voltage monitoring circuit that will cause the output

transistors to be tumed Off if the main battery voltage rises above a preset Over Voltage threshold.The value of that threshold is set by default and may be adjusted by the user. The default value and settable range is given in the controller model datasheet.

This protection is designed to prevent the voltage created by the motors during regenera- tion to be”amplified”to unsafe levels by the switching circuit.

The controller will resume normal operation when the measured voltage drops below the Over Voltage threshold minus a user definable hysteresis voltage.

The controller can also be configured to trigger one of its Digital Outputs when an Over Voltage condition is detected.This Output can then be used to activate a Shunt load

across the VMot and Ground wires to absorb the excess energy if it is caused by regen- eration.This protection is particularly recommended for a situation where the controller is powered from a power supply instead of batteries.

Undervoltage Protection

In order to ensure that the power MOSFET transistors are switched properly,the control- ler monitors the internal preset power supply that is used by the MOSFET drivers.If the internal voltage drops below a safety level,the controller’s output stage is turned Off.The rest of the controller’s electronics,including the microcomputer,will remain operational as long as the power supply on VMot is above the minimum voltage specified in the product datasheet or if Power Control is above 7V.

Additionally,the output stage will be turned off when the main battery voltage on VMot drops below a user configurable level that is factory preset at 5V.

Temperature-Based Protection

The controller features active protection which automatically reduces power based on

measured operating temperature.This capability ensures that the controller will be able to work safely with practically all motor types and will adjust itself automatically for the vari- ous load conditions.

When the measured temperature reaches 5C below the Over temperature limit,the con- troller’s maximum allowed power output begins to drop by 20%for every degree until the temperature reaches the Over temperature limit.Above this limit,the controller’s power stage tums itself off completely.The same applies to MCUTemp at 90°C-95°C degrees.

Note that the measured temperature is measured on the heat sink near the Power Transis- tors and will rise and fall faster than the outside surface.

The time it takes for the heat sink’s temperature to rise depends on the current output, ambient temperature,and available air flow (natural or forced).

IRoboteQ

Global Power Configuration Parameters

Short Circuit Protection

The controller has got two levels of short circuit protection software and hardware

protection.Some Roboteq controllers includes a circuit that will detect very high current surges that are consistent with short circuits conditions.Check with controller datasheet for details.

The firmware utilizes the current sensors in order to detect short circuit.When such a

condition occurs,the power transistor for the related motor channel is cut off within a

idle.

The protection is very effective but has a few restrictions:

Only shorts between two motor outputs of the same channel are detected.Shorts

between a motor wire and VMot are also detected.Shorts between motor output and Ground are not detected.

It is noted that the software short circuit triggering is affected also from the load induc- tance values and input battery voltage level.

Since the controller can handle very large current during its normal operation,Only direct short circuits between wires will cause a sufficiently high current for the detection to

work.Short circuits inside motors or over long motor wires may go undetected.

Mixed Mode Select

Mixed mode is available as a configuration option in dual channel controllers to create

tanklike steering when one motor is used on each side of the robot:Channel 1 is used for moving the robot in the forward or reverse direction.Channel 2 is used for steering and will change the balance of power on each side to cause the robot to tun.Figure 7-2 below llustrateshow the mixed mode motor arrangement.

Motor Channel Parameters

User Selected Current Limit Settings

The controller has current sensors at each of its output stages.Every 1 ms,this current is measured and a correction to the output power level is applied if higher than the user preset value.

The current limit may be set using the supplied PC utility.The maximum limit is dependent on the controller model and can be found on the product datasheet.

90 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Motor Channel Parameters

The limitation is performed on the Motor current and not on the Battery current.See “Bat- tery Curent vs.Motor Current”on page 28 for a discussion of the differences.

Selectable Amps Threshold Triggering

The controller can be configured to detect when the Amp on a motor channel exceeds a user-defined threshold value and trigger an action if this condition persists for more than a preset amount of time.

The list of actions that may be triggered is shown in the table below.

TABLE 7-2.Possible Action List when Amps threshold is exceeded

Action Applicable

Channel

Description
No Action Input causes no action
Safety Stop Selectable Stops the selected motor(s)channel with Fault Deceler ation,until command is moved back to idle or command direction is reversed
Emergency stop All Stops the controller entirely until controller is powered down,or a special command is received via the serial port

This feature is very different from amps limiting.Typical uses for it are for stall detection or “soft limitswitches”When,for example,a motor reaches an end and enters stall con- dition,the current will rise,and that current increase can be detected and the motor be made to stop until the direction is reversed.

Programmable Acceleration &Deceleration

When changing speed command,the controller will go from the present speed to the de- sired one at a user selectable acceleration.This feature is necessary in order to minimize the surge current and mechanical stress during abrupt speed changes.

This parameter can be changed by using the PC utility.Acceleration can be different for each

motor.A different value can also be set for the acceleration and for the deceleration.The ac-

celeration value is entered in RPMs per second.In open loop installation,where speed is not

actually measured,the acceleration value is relative to the Max RPM parameter.For example,

f the Max RPM is set to 1000 (default value)and acceleration to 2000,this means that the

controller will go from 0 to 100%power in 0.5 seconds.In closed loop Torque Mode the

Acceleration and Deceleration values are entered in miliAmps per second.In case of Safety

Stop the motor will ramp down based on the Fault Deceleration configuration value.

In order to by-pass the ramping process,either the acceleration or the deceleration values need to be set to 0.

Important Warning

Depending on the load’s weight and inertia,a quick or no acceleration can cause considerable current surges from the batteries into the motor.A quick or no

deceleration will cause an equally large,or possibly larger,regeneration current

surge.Always experiment with the lowest acceleration value first and settle for the slowest acceptable value.

Motor Operating Features and Options RoboteQ

Furthermore,by by-passing command ramp the controller cannot protect itself from high currents.

Forward and Reverse Power Adjustment Gain

This parameter lets you select the scaling factor for the power output as a percentage value.This feature is used to connect motors with a voltage rating that is less than the battery voltage.For example,using a factor of 50%it is possible to connect a 12V motor onto a 24V system,in which case the motor will never see more than 12V at its input

even when the maximum power is applied.

Selecting the Motor Control Modes

For each motor,the controller supports multiple motion control modes.The controller’s factory default mode is Open Loop Speed control for each motor.The mode can be

changed using the Roborun PC utility.

Open Loop Speed Control

In this mode,the controller delivers an amount of power proportional to the command

information.The actual motor speed is not measured.Therefore the motor will slow down if there is a change in load as when encountering an obstacle and change in slope.This

mode is adequate for most applications where the operator maintains visual contact with the robot.

Power Command PWM

Motor

FIGURE 7-3.Open loop mode

Closed Loop Speed Control

In this mode,illustrated in Figure 7-4,an optical encoder (typical)or an analog tachometer is used to measure the actual motor speed.If the speed changes because of changes in load,the controller automatically compensates the power output.This mode is preferred in precision motor control and autonomous robotic applications.Details on how to wire

the tachometer can be found in “Connecting Tachometer to Analog Inputs”on page 48. Closed Loop Speed control operation is described in”Closed Loop Speed Mode”on page 133.On brushless motors,speed may be sensed directty from the motor’s Hall or other internal Sensors and closed loop operation is possible without additional hardware.

Closed Loop Speed Position Control

In this mode,the controller computes the position at which the motor must be at every 1ms.Then a position loop compares that expected position with the current position and applies the necessary power level in order for the motor to reach that position.This mode is especially effective for accurate control at very slow speeds.Details on this mode can be found in Closed Loop Speed and Speed-Position Modes on page 133.

In this mode,illustrated in Figure 7-6,the axle of a geared down motor is typically cou-

pled to a position sensor that is used to compare the angular position of the axle versus

a desired position.The motor will move following a controlled acceleration up to a user

defined velocity and decelerate to smoothly reach the desired destination.This feature of the controller makes it possible to build ultra-high torque “jumbo servos”that can be used to drive steering columns,robotic arms,life-size models and other heavy loads.Details on how to wire the position sensing potentiometers and operating in this mode can be found in”Closed Loop Relative and Tracking Position Modes”on page 141.

Introduction to Brushless Motors

SECTION 8

Brushless Motor

Connections

and Operation

This section addresses installation and operating issues specific to brushless motors.It is applicable only to brushless motor controller models.

Important Warning

This Manual refers to Firmware 2.x of Roboteq Motor Controllers.Many of the de- scribed features are either not available or do not work the same way (PID gains in particular)than in Firmware 1.x or prior.Refer to Manual v1.8 for earlier Firmware.

Introduction to Brushless Motors

Brushless motors,or more accurately Brushless DC Permanent Magnet Synchronous mo- tors (since there are other types of motors without brushes)contain permanent magnets and electromagnets.The electromagnets are arranged in groups of three and are powered in sequence in order to create a rotating field that drives the permanent magnets.The

electromagnets are located on the non-rotating part of the motor,which is normally in the motor casing for traditional motors,in which case the permanent magnets are on the ro- tor that is around the motor shaft.On hub motors,such as those found on electric bikes, scooters and some other electric vehicles,the electromagnets are on the fixed center part of the motor and the permanent magnets on the rotating outer part.

Brushless Motor Connections and Operation RoboteQ

FIGURE 8-1.Permanent Maanet Synchronous Motor construction

As the name implies,Brushless motors differ from traditional DC motors in that they do not use brushes for commutating the electromagnets.Instead,it is up to the motor con- troller to apply,in sequence,current to each of the 3 motor windings in order to cause the rotor to spin.There are fundamentally two methods of generating the rotating magnetic field in the motor’s winding:

·Trapezoidal Commutation

· Sinusoidal Commutation

Within each commutation method is then a method for detecting the actual position of the rotor in order to synchronize the generated rotating field.These are:

· Hall sensors

· Encoders(Absolute or relative)

· Sensorless (Trapezoidal only)

All Roboteq brushless controllers support Trapezoidal with Hall sensor feedback.Sinusoidal and alternative rotor detection techniques are available on selected models.Refer to the controller’s datasheet to determine which modes are supported.

Number of Poles

One of the key characteristics of a brushless motor is the number of poles of permanent magnets pairs it contains.A full 3-phase cycling of motor’s electromagnets will cause the rotor to move to the next permanent magnet pole.A full 3-phase cycle is known as electri- cal turn which will be different from the physical (mechanical)tum of the shaft if the motor number of pole pairs is greater than one:increasing the number of pole pairs will cause the motor to rotate more slowly for a given rate of change on the winding’s phases.

Roboteq controllers use the number of motor pole pairs to measure the number of turns a motor has made as well as motor speed.

Determining the Number of Poles

The number of pole pairs on a particular motor is usually found in the motor’s specifica- tion sheet.The number of pole pairs can also be measured by applying a low DC current (around 1A)between any two of the three motor phase wires and then counting the

number of cogs you feel when rotating the motor by hand for a full turn.It can also bede- termined by rotating the motor shaft by hand a full turn.Then take the number of counts reported by the hall counter in the Roborun PC utility,and divide it by 6.

#Pole Pairs =Hall Counts per turn /6

Or by sending the configuration command:

^BPOL channel nn

See “BPOL”in the command reference section for details.This parameter is not need-

ed for basic trapezoidal motor operation with Hall Sensor feedback and can be left at its default value.It is needed if accurate speed reporting is required or to operate in Closed Loop Speed or Position modes.The number of pole pairs is a critical configuration in sinu- soidal mode.

Entering a negative number of pole pairs will reverse the measured speed and the count direction.It is useful when operating the motor in closed loop speed mode and if other- wise a negative speed is measured when the motor is moved in the positive direction.

Trapezoidal Switching

In trapezoidal switching,the controller applies current to two of the 3 motor wires,in turn and in altemating direction.A total of 6 combinations of current flow are possible,result- ing in the rotor getting a changing magnetic field every 60 degrees of electrical rotation.

The controller must therefore know where the rotor is in relation to the electromagnets so that current can be applied to the correct winding at any given point in time.The simplest and most reliable methodis to use three Hall sensors inside the motor.The diagram be- low shows the direction of the current in each of the motor’s windings depending on the state of the 3 hall sensors.

FIGURE 8-3.Hall sensors sequence

Brushless Motor Connections and Operation lRoboteQ

Hall Sensor Wiring

Hall sensors connection requires 5 wires on the motor:

· Ground

· Sensor A Output

· Sensor B Output

· Sensor C Output

· +5V power supply

Sensor outputs are generally Open Collector,meaning that they require a pull up resistor in order to create the logic level 1.Pull up resistor of 4.7K ohm to +5V are incorporated

inside all controllers.Additionally,1nF capacitors to ground are present at the controller’s input in order to remove high frequency spikes which may be induced by the switching at the motor wires.

GND

FIGURE 8-4.Hall sensor inputs equivalent circuit

Both 120 degrees and 60 degrees Hall sensors spacing,are supported (see “HPO”in the command reference section).Hall sensors can typically be powered over a wide voltage range.The controller supplies 5V for powering the Hall sensors.

Important Notice

120 degrees Hall sensor spacing is by far the most common.Use 60 degrees only if that is specified in the motor’s documentation or label.

Unless specified otherwise in the datasheet,Hall sensor connection to the controller is

done using Molex Microfit 3.0 connectors.These high quality connectors provide a reliable connection and include a lock tab for secure operation.The connector pin-out is shown in the controller model’s datasheet.

In several controller models,the Hall inputs can be alternatively mapped to digital inputs on the l/O connector.This makes it possible to use the hall sensors for rotor commutation, and SSl sensors for other purposes at the same time (see “MLX”in the command ref-

100 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

erence section).Note that in the case where digital inputs are configured as Hall inputs, pull-up resistor from the input pin to the +5V must be added externally.Use 4.7K resistors wired as shown in Figure 8.4.

Important Warning

Keep the Hall sensor wires away from the motor wires.High power PWM switching on the motor leads will induce spikes on the Hall sensor wires if located too close. On hub motors where the Hall sensor wires are inside the same cable as the motor power wires,separate the two sets of wires the nearest from the motor as possible.

Important Notice

Make sure that the motor sensors have a digital output with the signal either at 0 or at 1.Sensors that output are gradually changing are typically analog signals will cause the motor to run imperfectly.

Hall Sensor Verification

Hall Sensor miswiring is a very common cause when the motor is not running.You can send the following query to verify that the hall sensors are seen by the controller:

?HS [channell

The reply is one or two numbers,depending on the number of channels,of values be- tween 0 and 7 with each bit representing the state of each of the HA,HBand HC sen- sors.

Turn the motor slowly by hand while sending frequent ?HS queries.Verify that all valid combinations appear at one time or the other and that none of the invalid combination ever show.

For 120 degrees spaced sensors,1-2-3-4-5-6 are valid combinations,while 0 and 7 are invalid combinations.For 60 degrees spaced Hall sensors,0-1-3-4-6-7 are valid combina- tions,while 2 and 5 are invalid combinations.

Note that HS query does not work on the first generation HBL and VBL family of products.

Hall Sensor Wiring Order

The order of the Hall sensors and these of the motor connections must match in order for

the motor to spin.Unfortunately,there is no standard naming and ordering convention for

brushless motors.

The Hall Sensor and Motor Phases naming convention used in Roboteq controllers is A, B and C for the sensors and U,V and W for the motor phases.When rotating the motor

shaft clockwise by hand,the controller expects the sensor A to be a mirror of the voltage generated between wires U and W,sensor B between V and U,sensor C between W and

Brushless Motor Connections and Operation lRoboteQ

V.See figure 8-5.The sine wave voltage will be inverted when turning the motor in the opposite direction.

FIGURE 8-5.Relation between hall sensor and U V W windings

Determining the Wiring Order Empirically

While probing with an oscilloscope gives the definite order,a simpler and quicker way is to find the correct combination by trial and error.To do this,you can either connect the

motor wires permanently and then try different combination of Hall sensor wiring,or you can connect the Hall sensors permanently and try different combinations of motor wiring. There is a total of 6 possible combinations of wiring three sensors on three controller

inputs.There are also 6 possible combinations of wiring three motor wires on three con- troller outputs.Only one of the 6 combinations will work correctly and smoothly while allowing the controller to drive the motor in both directions.

Alternatively,instead of swapping Hall sensors or motor phases,you can use the “Hall

Sensor Map”configuration from the PC Utility menu (see”HSM”in the command refer- ence section).,or from the following console command:

^HSM ch nn

Try each of the 6 available values of HSM (0-5)and retain the one that will make the motor spin in both directions while drawing the same low current.

When testing a combination,apply a low amount of power (5 to 10%).Applying too high power may trigger the stall protection.Once a combination that make the motor spin is found,increase the power level and verify that rotation is smooth,at very slow speed and at high speed and in both directions.

Important Notice

Beware that while only one combination is valid,there may be other combinations that will cause the motor to spin.When the motor spins with the wrong wiring

combination,it will do so very inefficiently.Make sure that the motor spins equally smoothly in both directions.Try all 6 combinations and select the best.

Trapezoidal Switching

Important Notice

It is not possible to change the motor direction by changing the Hall/Phase order.If the motor is not tuning in the desired direction,chose “Inverted”in the “Motor Di- rection”configuration menu in the PC Utility.

Hall Sensor Alignment

It is very important that the hall sensors be precisely aligned vs the electromagnets in- side the motor so that commutation be done exactly at the right time.Bad alignment will cause the motor to run inefficiently.

A first,and generally reliable clue that Hall Sensors are not properly aligned is to run the motor in the forward and then reverse direction while in Open Loop.Verify that for a given command level in open loop,the motor reaches the identical speed and consumes the

same amount of current.

Another simple verification methodis to use an oscilloscope to view the shape of the

phase voltage.While the motor is running,place a probe between ground and any of the motor phases.Verify that the voltage looks like the shape on the figure 8-6.Look for sym- metrical ramps on the left and night.An imbalance in the ramps indicates that the commu- tation happens at the wrong time because of bad Hall Sensor position.

FIGURE 8-6.Ground to Phase voltage waveform on motor with correct and wrong commutations

The most precise evaluation of the Hall Sensors alignment is done using an oscilloscope and the circuit descnbed in figure 8.7.Compare the shape of the Hall Sensor signal to this of the voltage that is generated on the motor phases as the shaft is rotated by an external force.Verify that the zero-crossing of the phase voltages is occurring at exactly the same time as the Hall Sensor transitions,as shown in figure 8-5.

Important Warning

Hall Sensor misalignment cannot be corrected by the controller.Contact the motor manufacturer for remedy.

Hall+Encoder Trapezoidal

In case of misaligned hall sensors,a quadrature encoder can be used in order to help in

commutation and make it more optimal.In Hall+Encoder trapezoidal both Hall Sensors and a quadrature encoder are used.The Hall sensors are used in order to define the electrical 0 on the rotor.Then the encoder is used in order to commutate in a 6-state trapezoidal mode.

In that way the bad hall alignment can be fixed by modifying accordingly the BADJ config- uration command.

Hall+Encoder Trapezoidal mode is selected via the Switching Mode configuration menu in the Roborun PC utility.

Sinusoidal Commutation

Sinusoidal Commutation

In sinusoidal commutation,all three wires are permanently energized with a sinusoidal current that is 120 degrees apart on each phase as shown in figure 8-9.

FIGURE 8-9.Three phase current creating a rotating magnetic field

At its most basic operation,the controller measures the rotor’s angular position,adds or subtracts 90o depending on the desired rotation direction,and applies the result to the 3-phase PWM generator.

FIGURE 8-10.Simplified 3-phase sinusoidal model

As the motor turns,the phase on each wire is changed in order for the magnetic field to always be perpendicular,and therefore create the maximum radial force to the rotor.

FIGURE 8-11.Magnetic field perpendicular to rotor magnets

Brushless Motor Connections and Operation RoboteQ

The principle benefit of sinusoidal commutation is the quiet,rumble-free,motor operation resulting from the smoothly rotating and always aligned magnetic field.

However,sinusoidal commutation is more complex to configure,calibrate,tune and oper ate.For best and fastest results it is recommended that you follow these step rigorously:

1-Configure the Controller for Sinusoidal Commutation (page 100)

2-Select and Configure a Supported Angle Sensors (page 102)

Configuring the Number of Motor Pole Pairs

The number of Motor Pole Pairs is a critical parameter for sinusoidal combination.A full

3-phase cycling of motor’s electromagnets will cause the rotor to move to the next per-

manent magnet pole.A full 3-phase cycle is known as electrical turn which will be differ- ent from the physical (mechanical)turn of the shaft if the motor number of pole pairs is

greater than one.The figure below show the relationship between mechanical degree and electrical degree in the case of a two pole pairs motor.

Entering a negative number of pole pairs will reverse the measured speed and the count direction.It is useful when operating the motor in closed loop speed mode and if other- wise a negative speed is measured when the motor is moved in the positive direction.

Configuring Number of Sensor Poles

Single pole absolute sensors like Resolvers,sin/cos and SSl encoders typically return an angular value that is equal to the mechanical angle.The controller then converts the mea- suredangle into the electrical angle for its internal operation,using the formula:

Electrical Angle =(Sensor Angle*Number of Poles)modulo 360

Brushless Motor Connections and Operation lRoboteQ
When used on motors with a high number of pole pairs,single pole sensors will measure the electrical angle with degrading resolution as the number of motor poles is higher.For example,a single pole sensor with 1o resolution on a 10 pole motor will produce an elec- tric angle evaluations with 10o resolution,which will result in less than optimal operation.

To resolve this problem,some absolute sensors are available in multiple pole versions. In that case,the sensor will outputs a 0-360 angle value multiple times during a full turn. Note that the controller will not work if the number of sensor poles is higher than the

number of motor poles.

Enter the number of Sensor Poles in the SinCos/SSl Sensor Poles configuration menu in the Roborun PC utility.

Important Notice

The number of motor poles and sensor poles are very important configuration pa- rameters in sinusoidal mode.Using the wrong values will produce erratic behavior and possibly damage.

Selecting and Configuring Supported Angle Sensors

In order for the proper voltage and phase to be applied to each of the 3 motor wires,the rotor angular position must be known with precision at all times.Roboteq controllers sup- port several sensors for achieving this.

Then select the method for capturing the rotor angle of the rotor as the motor spins.This is done using the Sinusoidal Angle Sensor configuration menu in the utility.

^EPPR channel nn

Optimally,the encoder should have a PPR that is at least 128 x the number of pole pairs. For example a motor with 4 pole pairs should have a 128×4 =512 Pulse per revolution.

This will result in 2048 counts for a full turn of the rotor,and therefore the electrical angle to be measured with 360/2048*4=0.7 degrees,resulting in a very smooth changing sinusoidal drive to the motor.A significantly lower resolution encoder will results in a step- ping sinusoid.A higher resolution encoder will not improve the waveform.

Brushless Motor Connections and Operation RoboteQ
Since encoders do not give an absolute position,a reference search sequence is per-
formed automatically by the controller at every power up or when the controller switches
from a different mode to sinusoidal mode with encoder feedback
The search can also be forced manually by pressing the Sensor Setup button on the Diag-
nostic tab of the PC utility,or by sending the following maintenance command from the
console or the serial/USB port
%CLMOD 2 (for channel 1)or
%CLMOD 3 (for channel 2).
Before trusting that reference search will be successful at every power up,try repeated-
ly to send the sensor tuning (%CLMOD)command under rea-life load conditions.After
reference search is completed,verify that the motor turns with the same efficiency in the
forward and reverse direction.
Proper operation of the encoder can be verified by viewing the counter with the query:
?C [channel]
And verifying that it increments by the Encoder’s CPR (counts per revolution,or PPR*4)
when making a full turn,and returns to its original value after a full turn in the reverse di-
rection.
Hall-Only
In this mode,the Hall sensors are used to determine the angular position of the rotor.
Since transitions of the Hall pattern occur at every 60 degrees only,the controller will
estimate the current angle by interpolating in between two transition based on the cur
rent motor speed.This technique works well as long as speed is stable and changes are
relatively slow.It also requires that the magnets and sensors are positioned with precision
inside the motor,which is not always the case in low cost motors.Compared to Trape-
zoidal mode,this mode will result is quieter motor operation because of the sinusoidal
commutation.
Proper operation of the Hall sensors can be verified by checking that the hall counter
changes by6*the number of poles over a full mechanical turn in the PC Utility or by us-
ing the query:
?CB[channel]
Alternatively,the following query can be run to view the state of the logic level of each
Hall inputs.
?HS[channel]
The Hall-only mode requires only a one time tuning during which their actual angular po-
sition of each Hall sensor will be detected and stored.See “Automatic Sensor Setup”on
page 107.

Sinusoidal Commutation

Hall +Encoder

If the motor is fitted with Hall sensors and an Incremental Encoder,the controller can

be configured to use both sensors together.The Encoder’s PPR must be configured as

described above.In this mode,the controller’s operation is identical to when an Encoder alone is used for feedback,except that there is no need for the reference search se-

quence described above.When first energized,the motor will operate using the Hall sen- sor until the first change to the Hall pattern is detected.This will set the angle reference for the encoder.For this mode,it is critical that both the number of Encoder PPRs and the motor number of pole pairs be entered correctly.Both counters must count in the same direction.

The Hall Encoder mode requires only a one time tuning during which their actual angular position of each Hall sensor will be detected and stored.See “Automatic Sensor Setup” on page 107.

See above and below how to verify that the Encoder and Hall sensors are operating cor rectly.

Sin/Cos Analog

Some controller models can be interfaced to absolute position sensors with Sine/Cosine output.These sensors are usually made using Hall technology and are built into the motor. They provide two analog voltage output that are usually 90 degrees apart.The rotor angle is determined by measuring the voltage ratio between the two signals.The controller can compensate for differences in amplitudes between the two signals.

There are sensors whose signals are not 90 degrees apart.The controller can be con- figured for use with sensors that have practically any phase shift.This is done using the PSA-Phase Shift Angle configuration parameter.Note that angles are in 0-511 degrees notation.

The proper operation of the Sin/Cos sensor can be verified by plotting in realtime the volt- ages of the sin and cos signals inside the Diagnostic tab of the PC utility

FIGURE 8-18.Diagnostic Tab with Auto Setup

Brushless Motor Connections and Operation RoboteQ
Or using the following queries.

?ASl [channel]

Sin/cos sensors require a one-time setup and calibration.See “Automatic Sensor Setup” on page 107.

Important Warning

The Tuning Fault LED will be on in the Roborun screen and the motor will NOT start if the Sin/Cos has not been setup/calibrated.

Important Notice

Electrical noise on the sensor output will cause wrong angle readings.Shield the

wires and keep them as far as possible from the motor wires.If noise persists,add a

10nF to 100nF ceramic capacitor between the input pin and ground pin on the con- troller’s connector

Synchro Resolver

Synchro Resolvers are a form of Sine/Cosine sensor based on transformer technology.It is composed of a fixed primary coil,and two secondary coils positioned at 90o from each other and that rotate with the rotor.A fixed frequency excitation voltage is fed in the pn- mary.As the secondary coils turn,and take turn being parallel with the fixed primary,the voltage amplitude induced in each varies as shown in the figure below.

Some advanced motors,incorporate an absolute position sensor with a high speed serial interface based on the SSl protocol.

Controllers support SSl encoders with resolution from 12 to 15bits.SSl encoders give the angle’s absolute position.Nevertheless,a calibration of the zero-angle reference must be done once in order to capture the mechanical offset of the sensor vs the actual 0 degrees position.

Brushless Motor Connections and Operation RoboteQ

Preparation for Automatic Sensor Setup

The rotor’s angle sensor is a critical element for good sinusoidal commutation.Wrong or unstable angle reading can cause excessive current consumption,vibration,or even dam- age.The sensor must be correctly and firmly attached to the motor so that it never slips during operation.The table below shows the setup and calibration steps required for each sensor type.

Note 1:Zero reference search must be performed at every powerup for Encoder mode

Note 2:Hall position mapping is optional but recommended for best results

Note 3:Linearity Correction is optional for digital encoders

Sensor setup and calibration is generally a one-time procedure.Sensor information is stored in the controller’s configuration and calibration flash.

Reference Search Power

During the automatic sensor setup phase,the controller will drive the motor coils with a slow-changing three phase current,creating a rotating magnetic field inside the motor.The rotor’s magnets are attracted to the field,causing the rotor to follow tum.For best accu- racy the rotor is driven for a full turn in the forward direction,and another full turn in the reverse direction.

For the reference search to work,the current that is injected into the motor must be

strong enough to pull the rotor in perfect alignment.The motor must not be loaded during this sequence.For best results,the current should be set equal to the motor’s nominal amps rating.

Enter the value in Amps s in the “Reference Seek Power”configuration menu in the Rob- orun PC utility.

Sinusoidal Commutation

Important Warning

Do not select an amperage value that is above the maximum nominal value pub- lished in the motor’s datasheet.

Important Warning

Calibration data is specific to a motor+sensor set.Changing the motor and/or sensor requires recalibration.

Sensor Min/Max Range

Analog sensors like Sin/Cos and Resolvers have voltage outputswings that can vary from one sensor to another.During Automatic Setup,the motor is forced into rotation and

the min and max voltages for each sensor output signal is captured over a full tum of the sensor.These values then determine offsets and multiplier that are saved in calibration memory and subsequently used to scale the signals as necessary to produce a correct angle measurement.

The min/max range calibration is a one time operation for a given sensor.

Zero Reference Search for Absolute Sensors

All absolute sensors (Sin/Cos,Resolver,SSl)cannot be trusted to be mounted so that

their 0 degree reference position exactly matches this of the motor’s windings.During

Zero Reference search,the motor is driven over known angular positions.The sensor mea- surement is compared with the expected rotor position and an Angle Adjustment vale is computed and stored in configuration memory.

Important Notice

All angles values entered or displayed by the controller are in 0-511 value where 0= 0 degrees or radians,and 511 is 360o or 2P radians.

Zero Reference Search for Incremental Encoders

Incremental Encoders do not output an absolute position value.The Zero Reference

search is therefore performed every time the controller is powered on.See also “Incre- mental Encoder-Only”on page 103

Hall Sensors Position Mapping

Hall sensors are often not precisely located at the 0,60,120,180,.…positions.While

some imprecision has little effect in trapezoidal mode,misalignment of even a few de-

grees will have disruptive effect when operating in sinusoidal mode.When used with Hall sensors,the automatic setup procedure captures and maps the angle at which each of the six hall transitions occurs within an electrical turn,regardless of their wiring order.

Linearity Correction Map

Sensor are not alway totally linear.This causes the sensed angle to be measured with

periodic errors along the sensor travel.During the automatic setup process,the controller maps the values read from the sensor for every mechanical degree over a full turn.It then build a correction table which is applied in real-time as the motor spins.

Encoder inputs and/or the Sin,Cos signals are all related to each other.Swapping any of the motor wires will make the motor turn in the opposite direction.Swapping any sensor cables affects the angle and counting direction.

The Automatic Setup will detect the wiring order of the motor and sensors,and set the

corresponding bits in the SWD configuration register in order to virtually swap the connec- tions so that all are moving/sensing in the same direction.

Running the Automatic Sensor Setup

The V2.x firmware has a new feature for Automatic Setup and Calibration of all the sup- ported rotor sensor types.With a simple click,it performs the following:

a.Find the sensor polarity with respect to stator winding connection and set the SWD Swap Windings configuration parameter.

b.Find angle offset from the stator zero degrees reference axis and store the value in the”BADJ”Angle Zero Adjust configuration register.

c.Map the angular position of the Hall sensors and store the values in the HSAT Hall Sensor Angle configuration table

d.Find themin,max and zero levels of the analog signals in case of sin-cos and

resolver for normalization of sine and cosine.The values are stored in the ZSMC

calibration register

After configuring the controller for sinusoidal mode (See page 100)and after selecting and configuring the Angle Sensor (See page 102),click on the Diagnostic tab of the Roborun+ PC Utility.

Important Notice

All angles values entered or displayed by the controller are in 0-511 value where 0= 0 degrees or radians,and 511 is 360o or 2P radians.

Select which motor channel to setup.Then click on the Motor/Sensor Setup button to launch the Automatic process.The process can also be initiated using the serial com- mands %CLMOD 2 for Channel 1 and %CLMOD 3 for Channel 2.

The motor will rotate at a RPM speed of 60/Number of Pole pairs.It will perform a full

turn in each direction and then stop.If the motor doesn’t turn,or turns with hesitations, Click on the Cancel button (or send %CLMOD 0).Make sure that the motor is not loaded. Adjust the Reference Search Current and try again.See “Reference Search Power”on

page 108

After setup is finished,depending on the sensor type,the Utility will print the following captured parameters on the console tab indicating that the process is complete:

Perform the Setup a few times to verify that it produces the same values.If the Zero Ref- erence in particular varies significantly,increase the Adjust the Reference Search Current and try again.See “Reference Search Power”on page 108.

The reference search will settle on a given electrical angle location.On a two pole motor, this electrical angle value exists in 2 mechanical locations for that motor.After performing a first search,rotate the motor shaft and repeat the search.On a perfectly constructed

motor,the search will settle at the same electrical angle on any of the other poles.In

practice,it is expected that the values will be off by one or two degrees from one pole to another.

If the value is consistent from one measurement to another,and difference is larger than a few degrees,this means the poles are not placed with precision in the motor and the motor will not run efficiently.If the difference is very large (20 degrees or more),it is likely that the angle sensor is not working correctly or that the number of poles of the motor

and/or sensor are not configured correctly.

Real-Time Charting

The Diagnostic tab includes a Fast-Updating that can be used to monitor useful infor mation during the Setup phase.For instance for observing that the Sin and Cos inputs see a Sinusoidal shaped signal as the motor turns,or that the captured angle is chang- ing steadily without noise or glitches.The chart is also useful for testing the motor im- mediately after Setup.The table below shows the parameters that can be monitored in the chart.

The linearity of the sensor will be displayed on the screen.If the graph is flat at around zero value,the sensor is linear and no correction is needed.If the shape is not a flat line and is clean (i.e.without random noise and glitches),press “Apply Correction”button.It can be beneficial to capture the linearity curve a few times and verify that it is consistent, before applying it.If the graphs is noisy,has glitches or looks otherwise unusual,then

press close an do the Sensor Linearity procedure again.If the performance is not better then the correction can be cleared by pressing the “Reset Linearity Correction”button.

Basic Motor Check

After the Automatic Setup completed successfully,the motor is ready to run.Use the

sliders on the Diagnostics Tab or on the Run Tab to apply power.Always run first in open loop,and preferably with no or light load.Apply first a small command (100-200)and verify that the motor spins without noise or rumble while using low current.Run the motor in the opposite direction and verify that for the same command value,it reaches the same speed and draws the same current.If the motor runs smoothly and with symmetrical per- formance,repeat the test with higher command value.

If the performance is different in the forward vs reverse direction,the zero reference may be wrong.Run the setup again.Noise or rumble typically points to problems with the sen- Sor.

Field Oriented Control (FOC)

In sinusoidal modes,using the rotor angle to determine the voltage to apply to each of the 3 motor phase works well at low frequencies,and therefore at low rotation speed.At higher speed,the effect of the winding inductance,back EMF and other effect from the motor rotation,create a shifting curent.The resulting magnetic field is then no longer op- timally perpendicular to the rotor’s permanent magnets.

FIGURE 8-25.Perpendicular and non-perpendicular fields

As can be seen in figure 8-25,when the magnetic field is at an angle other than exactly perpendicular to the rotor’s magnets,the rotor is pulled by a force that can bedecom- posed in two forces:

Lateral force causing torque,and therefore rotation.This force results from the Quadra- ture current lq,which is also called Torque current.

Parallel force that pulls the rotor outwards,creating no motion.This force results from the Direct Current ld,which is also called Flux current.

Field Oriented Control is a technique that measures the useful Torque current and wasted Flux current component of the motor current.It then automatically adjust the power (out-

FIGURE 8-26.FOC operation

Field Oriented Control is available on most models of Roboteq motor controllers.It uses a classical implementation as described in the figure 8-26.The current in the motor phase is captured,along with the rotor’s angle.From this are computed the useful lq and wasteful ld.Two Proportiona-Integral (Pl)regulators then work in parallel to control the output volt- age amplitude and phase so that the desired Torque(lq)and Flux (ld)currents are met.The desired Flux current is typically set to 0 for brushless dc motors,and so the regulator will work to totally eliminate the Flux current.The output of the Pl d-q axis current controllers yield the d-q axis reference voltage commands (Vd,Vq)applied to the motor through the Space Vector Pulse Width Modulation (SVPWM)technique.

Both Pl regulator have usersettable gains.They can be changed from the menus in the RoborunPlus utility.

Where nn =Gain*1000000,e.g.12500000 =12.5 (on version 2.x of firmware)

FOC Gains Determination &Tuning

Good PI gains are important for the controller to quickly reach and stabilize the desired ld and lq current.A very good approximation of the gain values can be calculated from the motor’s Resistance and Inductance using the formulas:

Flux Proportional gain =Motor Phase Inductance(Henry)”Bandwidth

Flux Integral gain =Motor Phase Resistance(Ohm)”Bandwidth

Bandwidth is in rad/sec and according to Nyquist criteria the current loop bandwidth can- not be more than the half of the current loop sampling time.Most commonly the current loop bandwidth is set to the 1/10-1/20 of the current loop sampling time.The current loop sampling time is at 1kHz.So if we choose as current loop bandwidth the 50Hz then:

1Hz=2π rad/sec

So for 50Hz Bandwidth =50*2π rad/sec=314.

Usually even smaller bandwidth can be as effective as the 50Hz.It is better to start with the smaller possible gains and then tune according to the behavior of the motor.Test in open loop with caution.

Example calculation for 50Hz bandwith,11mOhm Phase resistance and 90uH Phase In- ductance

Ki=0.011*314=3.45

Kp=0,00009*314 =0.028

The FOC Proportional and Integral gains for brushless dc motors could be automatically calculated from “Motor characterization”tool at Roborun+(see Roborun+Utility User Manual for more details).

FIGURE 8-27.FOC performance monitoring

Optimal performance is achieved when:

· FOC Quadrature Amps are close to 0.

· Motor Amps and FOC Torque Amps values are close.

· FOC Angle Correction is stable for stable motor Power (output voltage amplitude).

Check also when changing motor power how fast FOC Flux Amps is corrected to zero. Tune FOC Pl as necessary.

Unstable FOC correction is generally a sign of imperfections of the angle sensing (noise, non-linearity,bad calibration,…).Bad angle sensing causes the wrong values of ld and lq to be measured,which the FOC algorithm falsely attempts to correct,worsening the cur- rent stability.

Field Weakening

Field weakening is a technique that is used to achieve faster motor rotation speed.This

is done by having some Flux (ld)current,even though this also introduces some waste.

Field Weakening is therefore possible on Roboteq controller by loading a non-zero set

point for the Flux current.This can be done from the console,the serial port,or from a Mi- croBasic script with the command:

!GID ch Amps*10

The amount of Flux current should be different at low and high speed,typically starting with zero,and increasing after a given RPM threshold is reached.Below is an example of a MicroBasic script that changes the Flux set point according to such a rule

Interior Permanent Magnet Motor Operation

IPM(interior permanent magnet)motor is an Alternating Current (AC)synchronous motor, where the permanent magnets are inserted inside the rotor,while in brushless dc motors the permanent magnets are mounted on the surface of the motor,as illustrated in figure 8-29.

FIGURE 8-29.(a)IPM motor(b)brushless dc motor configurations
Below the basic structural and operating differences between the IPM and BLDC motor:

IPM

· Reduce the risk of a magnet being peeled off by centrifugal force

· Higher total torque (PM motor produces both magnetic and reluctance torque) ·Higher speed range (IPM motor has higher field weakening capability,due to the

insertion of the permanent magnets inside the rotor)

· Reduce the risk of Permanent Magnets demagnetization

· Higher efficiency (lower permanent magnet eddy current losses)

BLDC

· The permanent magnets are mounted on the surface of the rotor

·PMs are glued provokes aging due to centifugal forces and heat)or banded · Lower total torque 《BLDC produces only magnetic alignment torque)

· Lower speed range (BLDC motor has lower field weakening capability,due to the PMs location at the airgap)

· Lower efficiency (higher PM eddy current losses)

Due to the different IPM magnetic circuit and produced torque mechanism compared to brushless dc motors,both torque (lq)and field weakening (ld)currents needed for optimal Maximum Torque Per Ampere(MTPA)operation as shown in the following figure.

FIGURE 8-30.IPM motor required lg,Ild with produced electromagnetic torque.

In order to effectively operate the IPM motors at MTPA curve,the following data required to be set during controller configuration from Roborun+utility:

D-axis Stator Inductance (Ld-mH):0.0

Q-axis Stator Inductance (Lq-mH):Q.0

Voltage Constant (Vk-V/kRPM):0.0

Or by sending the configuration command for Single Channel Controllers:

NLD cc nn

where cc =motor channel and nn =motor d-axis inductance (H)*1000000

ALO cc nn

where cc =motor channel and nn =motor q-axis inductance (H)*1000000

AVK cc nn

where cc =motor channel and nn =peak value of motor induced phase to phase voltage amplitude (produced back-emf)per krpm speed *1000

Above values are necessary in order to calculate the optimal ld,lq current commands

needed to be applied to FOC motor operation.Typically,these values are included in each IPM motor technical datasheet.Alternatively,the d-q axis motor inductances can be cal- culated from “Motor characterization”tool at Roborun+utility (see Roborun+Utility User Manual for more details).

Furthermore,the switching mode should be set to”Sinusoidal”and the FOC gains should be inserted according to the method described in “FOC Gains Determination &Tuning”

chapter at Section 8,considering as phase inductance the d-axis inductance Ld for flux

proportional gain and q-axis inductance Lq for torque proportional gain,respectively.It is noted that the IPM motor operation algorithm applies only at close loop operating modes, including FOC torque and flux gains.In all other cases,IPM motor can operate as a brush- less dc motor.

Example:

Consider the IPM motor with the following characteristics provided from manufacturer:

R(phase resistance)=85 mOhm

Ld (d-axis inductance)=580 uH

Lq(q-axis inductance)=850 uH

The FOC gains for 50 Hz current loop bandwidth are calculated as follows:

Torque proportional gain =D-axis inductance (H)*Bandwidth =0.000850*314 =0.267

Torque integral gain =Phase resistance (Ohm)*Bandwidth =0.085*314 =26.69

Flux proportional gain =D-axis inductance (H)*Bandwidth =0.000580*314 =0.182

Flux integral gain =Phase resistance (Ohm)*Bandwidth =0.085*314 =26.69

Sensorless Trapezoidal Commutation

Some Roboteq controllers models support trapezoidal commutation without the need for Hall or other sensors.These models use the code letters “SM”in their product reference (e.g.KSM1660).Roboteq’s sensorless control of BLDC motors uses back-EMF integration technique which provides good startup and precise commutation timing.

Important Notice

The Sensorless technique and settings described in this section only apply to firm- ware revision 2.0 and newer.Earlier implementation of Sensorless commutation has been retired and replaced.

Theory of Operation

At any given time during rotation,two windings are energized and the third is floating. When a BLDC motor rotates,each winding generates BEMF.This BEMF,and therefore the rotor position,can be sensed by monitoring the floating winding.

FIGURE 8-31.Active and fioating phases

126 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Sensorless Trapezoidal Commutation

The figure above shows the state of the transistorswitches during one of the six commu- tations phases.The current flows from the battery through the U winding,then through the V winding to ground.The W winding is floating.Since no current is flowing through W, the W terminal has the voltage potential of the BEMF that is induced in the W winding, added to the voltage at the motor’s center point.The center point motor is exactly half the V+voltage,assuming that all windings have the same resistance.

FIGURE 8-32.Sixephases Trapezoidal commutation,BEMF and Zero Crossing

The figure above shows the voltage at each of the windings during the 6 commutation phases.Notice how the voltage of the floating phase ramps between O and V+,and be- tween V+and 0,as the rotor moves 60 degrees.The point in the ramp that is exactly at half the supply voltage is called Zero Crossing.Commutation must occur 30 degrees of rotation later.Roboteq controllers use Back EMF Integration technique in order to deter mine that precise moment.

Phase Voltage

Back EMF Integrator

FIGURE 8-33.Commutation based on Back EMF Integration

Detection of rotor position using the BEMF at zero and very low speeds is not possible. At startup,the motor is therefore operated by applying a fixed commutation sequence and runs as a stepper motor until sufficient speed is gathered to detect Back EMF and Zero Crossings.Sensorless can therefore NOT be used if torque is required at stall or

Brushless Motor Connections and Operation RoboteQ
very slow speed.Nevertheless,there are many applications (e.g.,fans,pumps,watercraft thrusters)that do not require high torque at very low speed.

Important Notice

Do not use sensorless commutation if torque is required at start or at very low

speed.Always use sensored motors when driving wheels.Sensorless works best for driving propellers or fans.

Sensorless Parameters

The following parameters need to be tuned for trapezoidal sensorless to work optimally.

· Startup Frequency (SSF):This is minimum frequency (electrical Hz)at which the motor will always try to commutate during motor start or when slowed down.

· Back EMF Integrator Limit (SVT):This defines the threshold at which the integrated back-EMF of a given phase will trigger the commutation.

· Back EMF Coupling Constant (BECC):In case of non-ideal back-EMF waveforms, this number is required to compensate for back-EMF coupling due to other two phases.

The “Startup Frequency (Hz)”is set to 10Hz by default.This frequency works for practical- ly all motors.Some motors with high friction,heavy load and/or high inertia may not start at all,or start unreliably.If this occurs,try different Startup Frequency values.

In the sensorless mode the motor will spin regardless of the phase wiring order.If the

motor spin in the opposite direction than the one desired,swap any two of the three mo- tor wires,or change the motor direction to Inverted in the motor configuration..

The number of poles setting is not necessary in order for the motor to run.The number of poles is only used to measure the motor’s rotation speed.Enter a negative number of poles in order to change the speed polarity and count direction.

Sensorless PWM Frequency

PWM Frequency is variable when operating in sensorless mode.At startup and very low speeds,the applied PWM Frequency is 6kHz.As the motor speeds up,the PWM Fre-

quency is automatically increased up to 45kHz max.These settings work in practically all conditions and should be left unchanged

Sensorless Auto-tuning

An auto-tuning mechanism is provided for determining the BECC and SVT values.Beware that the motor will reach maximum speed during calibration/auto-tuning.The auto-tuning sequence lasts around one minute.

Make sure the controller is configured in open loop.Then,from the Diagnostics tab of

the Roborun+Utility,click on the”Motor/Sensor Setup”button from the diagnostics tab of the Roborun+Utility.The motor will ramp up to two different speeds.If motor fails to start,or starts unreliably,it may be necessary to adjust the Startup Frequency.See “Sen- sorless Parameters”section above.

128 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

Operating Brushless Motors

After the setup is complete,the motor will stop,BECC and SVT values will be printed on the console and saved in the controller’s configurations flash memory.

In case BECC is reported as a negative number,the calibration will be treated as a failure, and the error message “BEMF Integration Limit Detection FAILED!”will be displayed in the console

If the calibration was successful,message “BEMF integration limit detection OK”will be printed in the console and the values of BECC and SVT will be displayed too,then the motor is ready to use.Send motor commands in open loop and verify that it runs in both direction with reliability startup.

Further verification is possible by using an oscilloscope connected to any of the motor phases.Verify that the signal is symmetrical as shown in figure 8-5.If it is imbalanced, this means that the Back EMF Integrator Limit (SVT)needs further adjustment.You can change the value manually until the left and right ramps look symmetrical.

Important Warning

Beware that the motor will spin at maximum speed during calibration/auto-tuning. Make sure it is safe to do so before initiating.Be ready to cut to power instantly at any time during the tuning process.

Closed Loop Modes in Sensorless

Closed loop speed mode can be used with sensorless motors.The speed is determined by measuring the time between commutations.Sensorless motors will work the same as sensored motors and require similar PID tuning.The only limitation is at very slow speed where the motor cannot be made to go slower than the RPM resulting from the Startup Frequency parameter.

Position modes,and the Speed Position modes cannot be used reliably with sensorless motors.

Operating Brushless Motors

This section covers operating features that are common to Brushless Motor control,re- gardless of the commutation mode.

Once configured and tuned,a brushless motor can be operated exactly like a DC motor and all other sections in this manual are applicable.In addition,the Hall sensors or encod- ers,provide extra information about the motor’s state compared to DC motors.This infor mation enables the additional features discussed below.

Stall Detection

The rotor sensors and the encoders can be used to detect whether the motor is spinning or not.The controller includes a safety feature that will stop the motor power if no rotation is detected while a given amount of power is applied for a certain time.Three combina- tions of power and time are available:

Brushless Motor Connections and Operation RoboteQ
· 250ms at 10%power

· 500ms at 25%power

· 1s at 50%power

If the power applied is higher than the selected value and no motion is detected for the corresponding amount of time,the power to the motor is cut until the motor command is returned to idle.This function is controlled by the BLSTD-Brushless Stall Detection

parameter(see “BLSTD-Brushless Stall Detection”in Command Reference section).Do not disable the stall protection.

A stall condition is indicated with the “Stall”LED on the Roborun PC utility screen.

In Trapezoidal modes using Hall sensors,the Stall detection looks for changes at any of

the Hall sensors inputs.In Sinusoidal modes,the detection uses the speed measurement from the rotor sensor.

Sensor Error Detection

Sensor Error Detection methods have been implemented based on the kind of sensors used.

The user can select one of three options,Disabled,Tolerant and Strict(see “SED- Sensor Error Detection;page 352).

· Disabled:All sensor errors are ignored

· Tolerant:The fault will be active after 5 errors.The counter is reset when the motor command is equal to zero or reverse its direction.

· Strict:The fault will be activate on the first sensor error occurrence.

If Hall sensor is configured,a sensor error detection can be activated when an invalid Hall state value is detected (for example O or 7 that means there is an error in cable connection)or a Hall State that is read during motor rotation is not expected (this can indicate noise in the sensor for possible failure).The user can read the counter of the errors using the run time command SEC.

If SinCos sensor is configured,the user can read the result of the equation (sin^2(x)+

cos^2(x))*1000 using the run time command SEC.The returned value is indicative of the quality of the sin/cos signal.The closer the value is to 1000 the better is the signal.

lmportant Notice

In close loop modes,it is quite possible to have the motor stopped while power is applied to them.That could happen while stopped uphill,for example.Select the appropriate triggering level for your application

Operating Brushless Motors

Speed Measurement using the angle feedback Sensors

Information from Hall,SPI/SSI,sin/cos sensors,(and even Sensorless)is used by the con- troller to compute the motor’s rotation speed.

When Hall sensors are used,speed is determined by measuring the time between Hall sensor transitions.This measurement method is very accurate,but requires that the mo- tor be well constructed and that the placement between sensors be accurate.On preci- sion motors,this results in a stable speed being reported.On less elaborate motors,such as low-cost hub motors,the reported speed may oscillate by a few percent.

Speed measurement is very precise with digital absolute sensors (SPl).Sin/Cos sensors operating without noise also give a very precise value.

The motor’s number of poles must be entered as a controller parameter in order to pro- duce an accurate RPM value.See discussion above.The speed information can then be used as feedback in a closed loop system.Motor with a more precise Hall sensor posir- tioning will work better in such a configuration than less precise motors.

If the reported speed is negative when the slider is moved in the positive direction,you can correct this by putting a negative number of poles in the motor configuration.This will be necessary in order to operate the motor in closed loop speed mode using hall sensor speed capture.

Distance Measurement using Hall,SSl or other Sensors

When Hall sensors are used,the controller automatically detects the direction of rotation, keeps track of the number of Hall sensor transition and updates a 32-bit up/down counter. The number of counts per revolution is computed as follows:

Counts per Revolution =Number of Poles*6

With Resolver or Sin/Cos sensors,the controller accumulates the sensor angle data to

recreate an accurate and high resolution 32-bit counter.For these sensors,the number of counts per revolution is:

Counts per Revolution =Number of Sensor Poles*512

With SSl sensor,the controller accumulates the SSl data difference to recreate an ac- curate and high resolution 32-bit counter.For these sensors,the number of counts per revolution is:

Counts per Revolution =Number of Sensor Poles *SSl Sensor CPR

The counter information can then be read via the Serial/USB port,CAN bus,or can be

used from a MicroBasic script.The counter can also be used to operate the brushless mo- tor in a Closed Loop Position mode,within some limits

Introduction to AC Induction Motors

SECTION 9

AC Induction

MotorOperation

This section discusses the controller’s operating features and options when using three phase AC Induction motors.

Introduction to AC Induction Motors

Three phase induction motors are the most common types of electrical motors.They have a very simple construction composed of a stator covered with electromagnets,and a rotor composed of conductors shorted at each end,arranged as a “squirrel cage”They work on the principle of induction where a rotating electro-magnetic field it created by applying a three-phase current at the stators electromagnets.This in turn induces a current inside the rotor’s conductors,which in turns produces rotor’s magnetic field that tries to follow sta- tor’s magnetic field,pulling the rotor into rotation.

FIGURE 9-1.AC-Induction Motor

Benefits of AC Induction Motors are:

·Induction motors are simple and rugged in construction.They are more robust and can operate in any environmental condition.

·Induction motors are cheaper in cost due to simple rotor construction,absence of brush- es,commutators,and slip rings

AC-induction-Motor-Operation lRoboteQ
·They are maintenance free motors unlike dc motors due to the absence of brushes, commutators and slip rings.

·Induction motors can be operated in polluted and explosive environments as they do not have brushes which can cause sparks

Asynchronous Rotation and Slip

AC Induction motors are Asynchronous Machines meaning that the rotor does not turn at the exact same speed as the stator’s rotating magnetic field.Some difference in the rotor and stator speed is necessary in order to create the induction into the rotor.The difference between the two is called the slip.

Slip is measured in Hertz.It is the difference of the frequency generated by the controller,

and the rotor’s frequency,as determined by the formula

f=((RPM/60)*NumberOfPoles)

Optimal slip varies from the motor to motor and is in the range of typically 2 to 10Hz.

As seen from the figure below,when the slip is 0,i.e.the rotor turns at exactly the same speed as the stator field,torque totally disappears.Within the stable operating region,the Torque is proportional to the Slip.The torque and motor efficiency then quickly drops when the slip grows past its optimal value.

FIGURE 9-2.Torque vs.Rotor Speed graph for ACIM

The main task of the motor controller is to generate a rotating magnetic field whose

frequency and strength is such that the rotor will operate within the motor’s optimal slip range.Three techniques are supported by Roboteq for achieving this:

Scalar,Volts per Hertz (VPH)

Constant Slip

Field Oriented Control

Each of these techniques,benefits,and limitations are described in the following sections

Selecting and Connecting the Encoder

Connecting the Motor

An AC Induction motors have just 3 power wires which must be connected to the control- ler’s U V and W terminals.The connection order is not important.However,swapping any two motor connections will make the motor turn in the opposite direction.

Selecting and Connecting the Encoder

A speed sensor must be used to measure and control the motor’s slip when running in

Constant Slip mode and Torque/Speed FOC mode.This is done using an incremental en- coder.Most AC induction motors come with a built-in quadrature encoder.These encoders typically have a relatively low number of counts.32 or 64 Pulses Per Revolution (PPR)rota- tion are typical values.A low count encoder results in low frequency pulses.

When using encoders up to 128 Pulses Per Revolution,the controller evaluates the rota- tion speed by measuring the time between encoder pulses.This results in measurement with a resolution of 0.1Hz even at full speed.

When using encoders with higher PPR,speed is measured by counting the number of encoder signal transitions over a 10ms period.Prefer therefore a high-count encoder of around 1000 PPR for better speed measurement resolution.

Unless otherwise noted in the product’s datasheet,all Roboteq’s AC Induction Motor

Controllers have to pull up resistors that can connect to open collector encoder outputs. Controllers also have capacitors to help filter out any electrical noises that contribute to fake encoder readings.

Testing the Encoder

To test the encoder,use the PC utility to enable the encoder and set its number of Pulses Per Revolution (PPR).Go to the Utility’s Run tab,enable the Encoder Count in the chart. Make a full turn of the motor shaft by hand.Verify that the counter has changed by the

number of PPR*4.

Prior to enabling Constant Slip or FOC Modes,operate the motor in open loop Volts per

Hertz mode with slip control disabled.To disable slip control,set the encoder as No Action in the configuration menu.

AC-induction-Motor-Operation lRoboteQ
Apply a positive motor command.Verity that the motor shaft is moving in the desired direc- tion.If the motor moves in the opposite direction,swap any two of the three motor cables,or change the motor direction to Inverted in the motor configuration.

If the motor moved in the desired direction,then verify that the encoder counter increments when a positive motor command is applied.If the counter decrements,theneither swap the A and B encoder wires or enter a negative number of PPRs in the encoder configuration.

Open Loop Variable Frequency Drive Operation

In its simplest operating mode,the controller will output to the motor a three-phasesinusoid whose voltage and frequency change together at a fixed ratio.This mode is called Scalar be- cause of the fixed ratio between the Voltage and Frequency that is applied to the motor.

The ratio is set by the VPH-Volts Per Hertz configuration parameter.

FIGURE 9-4.VPH graph for ACIM

The figure above shows an example of the resulting stator frequency for a given motor

command.In open loop mode,Motor commands range from -1000 to +1000 and result in

the output voltage to range between -VBat to +VBat respectively

As long as the motor is not overloaded,the rotor RPM will be

Figuring the Motor’s Volts per Hertz

Each motor has a value for the optimal Volts per Hertz ratio.It can be determined by

the operating frequency and rated voltage written of the motor’s label.The figure below shows values from a real motor.

FIGURE 9-5.ACIM label

For this motor,the VPH can be determined by dividing the 48V phase to phase motor

voltage amplitude by the 50Hz frequency.In this case 0.96 Volts per Hertz.It is worth

mentioning that the rated voltage in the calculated VPH is related to the amplitude of the phase to phase voltage (not RMS value).Therefore,if the motor manufacturer provides the nominal stator voltage in RMS,it should be transformed to peak voltage value.

You can validate that the rated VPH is applied if the motor at no load reaches the rated speed when applying maximum motor command (Power =1000).

Note that this value is for the optimal torque as rated on the label.If the load is a lot light- er,the VpH will be too high and result in excessive current consumption.If the load is a

lot heavier,the VpH will be too low and the motor will not be able to drive it.The VpH will therefore need to be different from this computed based on actual load conditions.Always first monitor the motor consumption at no load.Adjust the VpH to a lower value if the no load current appears too high.

Maintaining Slip within Safe Range

Open Loop,or Scalar,the mode does not require encoders for its operation.If the load is known to always be within the motor’s max torque,the motor can be trusted to always be able to drive it.In this case,an encoder does not need to be connected.If an encoder is connected -to measure and report speed,for example -then it must be configured as “No Action”in the PC Utility.

For added safety,however,an encoder can be installed and enabled to measure the ro- tor’s speed,and therefore the slip,in real-time.When the encoder is enabled and config- ured as “Feedback”the controller will lower the voltage and frequency if the slip exceeds twice the value stored in the Optimal Slip configuration.

Prior to enabling the encoder as Feedback,verify that the encoder count direction has the same polarity as the motor command.

Closed Loop Speed Mode with Constant Slip Control

In this mode,the controller will automatically adjust the voltage and frequency in order to reach and maintain the desired speed,even as the load is changing,while operating with- in the optimal slip range.

AC-induction-Motor-Operation RoboteQ
To configure this mode,first set the controller in open loop mode as described in the pre- vious section.Verify that the encoder is working and is counting with the correct polarity.

Once the encoder is verified to work and the motor spins in the open loop,follow these steps.Using the Roborun PC utility:

·Select Close Loop Constant Slip Mode

·Set the PID gains found in the Motor Output,Closed Loop Speed Parameters menus (do not use the FOC PID gains).Try first with gains of P=4,l=0.5,D=0.These values will produce adequate results in most cases.Additional turning may be needed.

·Set the Max RPM configuration to the speed that must be reached at full throttle (ie

when command =1000).Make sure to enter a value that is within the physical reach of the motor under the expected maximum load condition.

·Enter the lowest acceleration rate that is acceptable for the application.Rapid chang- es will create current surges and should therefore not be allowed to be higher than necessary.

·Save the settings to the controller.

The motor speed can now be set to be any value between O and plus/minus the max- imum RPM configured above when sending a command ranging from -1000 to +1000 using the serial,analog or pulse inputs.

The motor speed can also be set to an absolute RPM value by sending the S (Speed) command via serial,USB,CAN or Scripting.

When exercising the motor with the PC utility,monitor the Slip,the Rotor RPM,Stator RPM and the Motor Amps

The slip will stabilize at the Optimal Slip setting.

Field Oriented Control (FOC)mode Operation

Field Oriented Control (or Vector Drive)is a technique by which the magnetic field gen- erated in the stator is adjusted in relation to the field induced in the rotor in a manner to generate optimal torque at all times and all load conditions.

FIGURE 9-6.FOC OnACIM

The optimal rotation occurs when the magnetic field induced in the rotor is perpendicular with this of the stator.Practically the fields the two fields are never exactly perpendicular. As shown in the diagram above,the angled field I am made of an outward pulling flux field (ld)and perpendicular pulling torque field.The torque field is the one that causes the rota- tion and that the controller will maximize.Flux field is not causing any rotation and there- fore must be minimized.Some flux is necessary at all times,however,in order to create the induction in the rotor.

Field Oriented Control (FOC)mode Operation

The challenge in induction motors is that the rotor flux’s absolute position cannot be mea- sured physically.It is determined mathematically using known speed,voltage and current, and a model representation of the motor’s main parameters shown in the figure below.

These parameters include per phase rotor resistance ‘Rr’,rotor leakage inductance ‘Lir’,

in FOC,therefore,rotor flux and motor torque can be individually controlled regardless

of load and speed.FOC offers better dynamic performance,accurate curent control and ensures maximum efficiency,unlike traditional scalar control methods such as Open Loop VpHand Constant Slip Control.

Under FOC operation,AC induction motors can be run in either FOC torque mode or FOC speed mode.FOC torque mode allows users to command a torque to a motor in terms of Amps.While FOC speed will regulate the speed at the command/desired value.

Note that,with a bad tuning of FOC (flux and torque)PID,the motor Amps can be higher than the Amps Limit.If that happened,try use lower bandwidth for FOC tuning (see in

Chapter FOC Gains Determination &Tuning).

Configuring FOCTorque Mode

To configure FOC mode,first set the controller in Open Loop (Volts per Hertz)mode as

described in one of the previous sections.Verify that the motor is spinning in the desired direction and that encoder is working and is counting with the correct polarity.See Testing the Encoder section above.

Once the encoder is verified to work and the motor spins in the open loop,follow these steps.Using the Roborun PC utility:

·Enter the motor parameters under the section “Motor Parameters”in RoboRun

configuration.Usually,motor manufacturer will provide you an equivalent circuit of the induction motor that contains Rr,Rs,Lm,LIr,Lls.

·Set the Flux Amps.In order to find the optimal flux amps,run the motor in Volts per

Hertz (VpH)mode with small/no load using the motor’s rated VpH ratio.Then watch the flux amps in the PC utility.Enter this value in the configuration.This flux amps can be

AC-induction-Motor-Operation lRoboteQ
increased for low speed/high torque requirement and can be decreased (Field Weaken- ing)for high speed/low torque requirement.

·Set the operating mode to FOC torque.Set Amps limit according to the application’s need but do not exceed the motor specifications.

·Save the settings to the controller.

·Next step is to tune FOC (Flux and Torque)PID.Start with low proportional gain e.g. 0.1,and then set some Integral gain.Integral gain is more important in this case.

Alternatively use the method as described in chapter “FOC Gains Tuning”in Section 8, using the Stator Resistance(Rs)and the Stator Inductance (Ls).

·Monitor and Record the Flux Amps and Torque Amps for the desired motor channel when tuning the FOC PID.

·Put some high load on the rotor and command a step Torque Amps from the slider bar (say 10A).Record the “FOC Torque Amps”reading on the chart.If the step response reaches the desired (10A)steady state fast enough then the PID is can be considered tuned.If it is slow then increase integral gain.If the Torque and Flux Amps show noise at high speed or motor produces noisy sound,then lower your proportional gain Kp.

·Once FOC/current PID is tuned,FOC torque mode is ready to operate and FOC speed mode can then be tuned.Note:It is important to know the value of Flux Amps the mo- tor is designed to operate under.Flux Amps stay the same during entire FOC operation unless field weakening is used.

Now motor Torque can be set to any desired value from O to plus or minus the value stored in the Amps Limit configuration parameter,by sending a command of-1000 to +1000 using the slider,analog input,pulse input,scnipting,CAN or any other command mode.

Note that in Torque Mode,the Max Speed RPM configuration parameter is used to limit the motor speed if the motor is not loaded and the desired torque is below the torque

that can actually be reached by the motor under the current load conditions.For example, a torque command of 50A on an unloaded motor (that will never draw 50A)will cause the voltage to increase to the maximum value,and therefore the motor to maximum speed, unless the speed is limited by the Max RPM parameter.For more details see chapter

“Speed Limiting in FOC Torque Mode”below.

Note that,with bad tuning of FOC (flux and torque)PID,the motor might draw much high- er current than expected.If so,try using lower bandwidth for FOC gains.For more details see chapter “FOC Gains Determination &Tuning,page 122.

Configuring FOC Speed Mode

To configure FOC Speed mode,configure first the FOC Torque mode as described in the section above.

·Set the controller to FOC Speed Mode

·Tune speed loop PID in a similar manner as was done for FOC PID.Use the PID gains

found in the Motor Output,Closed Loop Speed Parameters menus (do not use the FOC PID gains).It can be started with Kp term and introduce small Kd term.Once transient re- sponse on the graph seems reasonable then Ki can be used to get rid of steady state error.

Now motor Speed can be set to any desired value from 0 to plus or minus the value stored in the Max RPM configuration parameter,by sending a command of-1000 to +1000 using the slider,analog input,pulse input,scripting,CAN or any other command mode.

E.g.use the Roborun slider,or the console command

IRoboteQ

Induction Motor Parameters Calculation

to set motor RPM to 800 on channel 1 when MaxSpeed is set to 1000 RPM.Correspond- ing if MaxSpeed is set to 2000 RPM,any value on the slider will give 2 times RPM.

Speed can be also set as an absolute RPM value using the S command from Serial,USB, CAN or Microbasic.

Speed Limiting in FOC Torque Mode

AC Induction Controllers provide a way of smoothly limiting the speed in FOC torque

mode to prevent motor runaways.The method for limiting the speed is based on PID

speed over-ride control which provides very smooth motor output but requires PID tuning.

The speed loop PID tuning can either be done in “FOC torque mode”at the speed limit or in“FOC Speed Mode”by looking at the response time.

· When in”FOC Torque Mode”command some torque to the motor and cause the motor to spin to the speed limit.Some low frequency ripple will be noticed in the speed which should be minimized by increasing PID gains.Increase the PID gains to a point where no nipple is seen.

·If in“FOC Speed Mode”tune the speed PID gains by looking at the response time of the motor.And then move to case 1)to check the ripple in the speed.

Induction Motor Parameters Calculation

The motor parameters of Induction Motors are crucial when the Field Oriented Control

Close loop torque/speed control is needed.More specifically,the rotor induced flux abso- lute position is determined mathematically using known speed,voltage and current,and a model representation of the motor’s main parameters shown in the figure below.

FIGURE 9-8.Electrical Representation of ACIM for motor characteristics calculation

These parameters include per phase rotor resistance ‘R;,rotor leakage inductance ‘L, mutual inductance ‘L and rotor leakage inductance ‘L,’core losses R,are neglected).

Furthermore,in order to set the FOC(Flux and Torque)PID gains,the Stator Resistance (R)and Stator Inductance(L)needed,according to the method as described in chapter “FOC Gains Tuning”at Section 8.The most common ways,to manually estimate induc- tion motor parameters through the controller,are to test induction motor under no-load and locked rotor conditions.

No load testing

The no-load test,like the open circuit test on a transformer,gives information about ex- citing flux l current,the magnetizing inductance L,and rotational losses.The test is per-

zero(s≈0).Therefore,the motor equivalent circuit is expressed as follows:

formed by applying balanced rated voltage on the stator windings at the rated frequency.

The small power provided to the motor is due to core losses,friction and winding loses.

The motor will consume the necessary flux I,current in order to establish the appropriate

magnetic field.Motor will rotate at almost a synchronous speed,which makes slip nearly

Assuming that the R,(2),L,(H)are much lower than the magnetizing inductance L(H),

the following equation can be extracted:

where V,(V)is the phase stator voltage applied (RMS value),f,(Hz)is the stator frequency

and |(A)is the RMS motor amps.

In order to implement the above mentioned no load test with RoboteQ induction motor controllers,please follow these steps:

· Set the operating mode to “Volts per Hertz”mode.Encoder feedback action needed.

· Configure the Volt per Hertz setting according to motor nominal voltage (peak value of stator voltage according to manufacturer)and frequency.

· Run the motor without load up to the maximum available voltage (Com-

mand=1000),utilizing small acceleration/deceleration value.Be sure that the con- figured volt per hertz is correct,by checking the “Stator speed RPM”to be approxi- mately equal to manufacturer’s synchronous rated speed.

·Calculate the applied V,by the following equation:

(9.2)
where m,is the output PWM level (%1000)applied which is equal to Motor Power output measurement in Roborun+utility (-1000 to 1000 range)and V is the battery volts M.in the considered no-load test them,is 1000,therefore the applied voltage can be calculated

· Measure the motor RMS current from the utility (Motor Amps).Furthermore,the peak amps value should be configured as “Rotor Flux current”in the configuration tab.

· Calculate the magnetizing inductance for the no load test according to equation (9.1).

Locked rotor testing

The locked rotor test,like short circuit test on a transformer,provides the information

about leakage impedances and rotor resistance.Rotor is at the standstill,while low volt-

age is applied to stator windings up to rated current.Due to the fact that the magnetizing

inductance Lis much higher that leakage phase inductances L,L it can be assumed

that there is no current is floating to Lparallel branch.Typically,leakage inductances Lw

Lshould be around 2-10%of the magnetizing inductance L.Since there is no rotation

· Configure the Volt per Hertz setting according to five times lower the motor

nominal voltage (peak value of stator voltage according to manufacturer)and

frequency (1/5 of nominal V/f).The reason for configuring lower V/f ratio than in

no-load test is to appropriately weaken the induced field and reduce the produced torque at startup,in order to be easier to lock the rotor for the test.

· Lock the rotor by appropriate tool/device and increase the command up reaching the 80%of the rated motor current.If the produced torque is high and the rotor cannot be locked,then reduce appropriately the Volt per Hertz at configuration and repeat the test.

SECTION 10

Speed-Position Modes

This section discusses the controller’s Closed Loop Speed modes.

Modes Description

Close loop speed modes ensure that the motor(s)will run at a precisely desired speed.If the speed changes because of changes in load,the controller automatically compensates the output votlage so that the motor maintains a constant speed.Two closed loop speed modes are available:

Closed Loop Speed Mode

This mode is the traditional closed loop technique where speed is measured with a speed sensor.The speed is compared to the desired speed and the speed PID control loop

output provides the reference current (if FOC torque gains are set)or voltage (if the FOC torque gains are zero)commands,in order to reach and maintain that speed.The internal current control is described in the Field Oriented Control (FOC)operation chapter.

In this mode,the controller computes the position at which the motor must be at every 1ms.Then a PID compares that expected position with the current position and applies the necessary reference speed (if speed and FOC torque gains are set)or voltage (if the speed and FOC torque gains are zero)command in order for the motor to reach that posi- tion.This mode is especially effective for accurate control at very slow speeds.

The controller incorporates a full-featured Proportional,Integral,Differential (PID)control algorithm for quick and stable speed control.

The closed loop speed mode and all its tuning parameters may be selected individually for each motor channel.

Motor Sensors

The controller can use a variety of sensors for measuring speed.For brushed DC,Digital Optical Encoders and Analog Tachometers may be used.For Brushless motors,the Hall sensors and all other types of rotor sensors can be used in addition to Encoders and Ta- chometers.Digital Optical Encoders may be used to capture accurate motor speed.

Analog tachometers are another technique for sensing speed.See “Connecting Tachome- ter to Analog Inputs”on page 48

Tachometer or Encoder Mounting

Proper mounting of the speed sensor is cnitical for an effective and accurate speed mode oper ation.Figure 10-1 shows a typical motor and tachometer or encoder assembly.It is always pref. erable to have the encoder connected to the motor shaft rather than at the output of a gearbox. If the encoder must be mounted after a gear box considers the effect of the gear backlash.A higher count encoder will typically be required to compensate for the lower rotation speed.

Brushless Hall Sensors as Speed Sensors

On brushless motor controllers,the Hall Sensors and most other types of rotor position sensors that are used to switch power around the motor windings,can also used to mea- sure speed and distance traveled.

Speed is evaluated by measuring the time between the transition of the Hall Sensors.A 32 bit up/down counter is also updated at each Hall Sensor transition.

Speed information picked up from the Hall Sensors can be used for closed loop speed op- eration without any additional hardware on both sinusoidal and trapezoidal commutation. Likewise,the position counter that is updated at every Hall transition can also be used to operate the motor in Speed Position mode.

Speed Sensor and Motor Polarity

The tachometer,encoder or brushless sensor 《Hall,Sin/Cos,SPl)polarity (i.e.which rota- tion direction produces positive or negative speed information)is related to the motor’s rotation speed and the direction the motor turns when power is applied to it.

In the Closed Loop Speed mode,the controller compares the actual speed,as measured by the sensor,to the desired speed.If the motor is not at the desired speed and direction, the controller will apply power to the motor so that it turns faster or slower,until reached.

Closed Loop Speed Mode RoboteQ
Important Warning

The speed sensor polarity must be such that a positive voltage is generated to the controller’s input when the motor is rotating in the forward direction.If the polarity is inverted,this will cause the motor to run away to the maximum speed as soon

as the controller is powered and eventually trigger the closed loop error and stop. If this protection is disabled,there will be no way of stopping it other than pressing the emergency stop button or disconnecting the power.

Determining the right polarity is best done experimentally using the Roborun utility (see “Roborun+Utility User Manual”)and following these steps:

1. Configure the controller in Open Loop Mode using the PC utility.This will cause the motor to run in Open Loop for now.

2. Configure the sensor you plan to use as speed feedback.If an analog tachometer is used,map the analog channel on which it is connected as “Feedback”for the select- ed motor channel.If an encoder is used,configure the encoder channel with the en- coder’s Pulses Per Revolution value.On the brushless motor,if the rotor sensor (Hall, Sin/Cos,.)sensors are used,configure the correct number of motor pole pairs.

3. Click on the Run tab of the PC utility.Configure the Chart recorder to display the speed information if an encoder is used.Display Feedback if an analog sensor is used.

4. Verify that the motor sliders are in the“0”(Stop)position.

5. If a tachometer is used,verify that the reported feedback value read is O when the motors are stopped.If not,adjust the Analog Center parameter.

6. Move the cursor of the desired motor to the right so that the motor starts rotating, and verify that a positive speed is reported.Move the cursor to the left and verify that a negative speed is reported.

7. If the reported speed polarity is the same as the applied command,the wiring is cor rect.

8. If the tachometer polarity is opposite of the command.If an encoder is used,swap its ChA and ChB outputs.Alternatively,swap the motor leads if using a brushed DC motor only.The speed polarity can also be inverted by entering a negative number of encoder PPR.On brushless motors,entering a negative number of poles will invert the speed measured by the Hall,SinCos,or Resolver sensor.If using SSl sensor,the speed polari- ty can be inverted by entering a negative number of SSl sensor resolution.

9. Set the controller operating mode to Closed Loop Speed mode using the Roborun utility.

10. Move the cursor and verify that speed stabilizes at the desired value.If speed is un- stable,tune the PID values.

Important Warning

It is critically important that the tachometer or encoder wiring be extremely robust. If the speed sensor reports an erroneous speed or no speed at all,the controller will consider that the motor has not reached the desired speed value and will gradually increase the applied power to the motor until the closed loop error is triggered and the motor is then stopped.

Controlling Speed in Closed Loop

Controlling Speed in Closed Loop

When using encoder feedback or Hall Sensor (brushless motor)feedback,the controller will measure and report speed as the motor’s actual RPM value.

When using analog or pulse as input command,the command value will range from 0 to +1000 and 0 to -1000.In order for the max command to cause the motor to reach the de- sired actual max RPM,an additional parameter must be entered in the encoder or brush- less configuration.The Max RPM parameter is the speed that will be reported as 1000 when reading the speed in relative mode.Max RPM is also the speed the controller will attempt to reach when a max command of 1000 is applied.

When sending a speed command via serial,CANbus,scripting or USB,the command may be sent as a relative speed (0 to +/-1000)or actual RPM value.

PID Description

The controller performs both Closed Loop Speed modes using a full featured Proportional, Integral and Differential (PID)algorithm.This technique has a long history of usage in con- trol systems and works on performing adjustments to the Power Output based on the dif- ference measured between the desired speed or position (set by the user)and the actual speed or position (captured by the sensor on the motor).

Figure 9-3 shows a representation of the PID algorithm.Every 1 millisecond,the controller measures the actual motor speed or position and subtracts it from the desired speed or position to compute the error.

The resulting error value is then multiplied by a user selectable Proportional Gain.The

resulting value becomes one of the components used to command the motor.The effect of this part of the algorithm is to regulate current if torque FOC gains are set or voltage (if torque FOC gains are zero)of the motor proportionally with the difference between

the current and desired speed or position:when far apart,high power is applied,with the power being gradually reduced as the motor moves to the desired speed or destination.

A higher Proportional Gain will cause the algorithm to apply a higher level of power for a given measured error thus making the motor react more quickly to changes in commands and/or motor load.

The Differential component of the algorithm computes the changes to the error from one 1 ms time period to the next.This change will be a relatively large number every time

an abrupt change occurs on the desired speed value or the measured speed value.The value of that change is then multiplied by a user selectable Differential Gain and added to the output.The effect of this part of the algorithm is to give a boost of extra power when starting the motor due to changes to the desired speed or position value.The differential component will also help dampen any overshoot and oscillation.

The Integral component of the algorithm performs a sum of the error over time.In Speed mode,this component helps the controller reach and maintain the exact desired speed

when the error is reaching zero (i.e.measured speed is near to,or at the desired value).In Speed Position mode,the Integral parameter can help maintain a slightly tighter difference between the desired and actual position,but makes no significant difference and can be omitted altogether.

PID tuning in Closed Loop Speed Mode

As discussed above,three parameters-Speed Proportional Gain,Speed Integral Gain, and Speed Differential Gain -can be adjusted to tune the Closed Loop Speed control al- gorithm.The ultimate goal in a well tuned PID is a motor that reaches the desired speed quickly without overshoot or oscillation.

Because many mechanical parameters such as motor power,gear ratio,load,and inertia are difficult to model,tuning the PID is essentially a manual process that takesexperimen- tation.

The Roborun PC utility makes this experimentation easy by providing one screen for

changing the Proportional,Integral and Differential gains and another screen for running and monitoring the motor.First,run the motor with the preset values.Then experiment with different values until a satisfactory behavior is found.

In Speed Mode,the Integral component of the PID is the most important and must be set first.The Proportional and Differential components will help improve the response time

and loop stability.

Try initially to only use a small value of l and no P or D:

P=0

l=1

D=0

These values practically always work,but they may cause the motor to be slowly reaching the desired speed.Increase the I gain to improve responsiveness but keeping it below the level at which the motor begins to oscillate.The experiment then with adding P gain,and different values of I.

In the case where the load moved by the motor is not fixed,tune the PID with the mini- mum expected load and tune it again with the maximum expected load.Then try to find

152 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

PIDTuning in Speed Position Mode

values that will work in both conditions.If the disparity between minimal and maximal possible loads is large,it may not be possible to find satisfactory tuning values.In this case,consider changing the PID gains on the fly during motor operation with seria/CAN commands of with a MicroBasic script

In slow systems,use the integrator limit parameter to prevent the integrator to reach sat- uration prematurely and create overshoots.Beware to set speeds that can physically be reached by the motor under load.If the motor is not physically able,there will be a loop error,which if it becomes too large,will cause a fault to be detected and the motor to be stopped.

PID Tuning in Speed Position Mode

As discussed,in Closed Loop Speed Position mode,every millisecond,the controller com- putes a successive desired position.The PID then works to make the motor follow the

computed trajectory.This mode works much better than the regular Closed Loop Speed mode when the motor must operate at very low speed.When the motor is stopped,it will maintain its position even if pulled,as for example on a robot stopped downhill.

The PID therefore must be tuned for position mode.In position mode (the Position Gains are used),most of the work is done by the proportional gain.It acts essentially as an

imaginary rubber belt between the controller’s internal destination counter and the motor: the higher the difference,the more the belt is stretched,and the stronger the motor will turn.Once the imaginary belt has stiffened the motor will run at the desired speed.

Try initially with only a small amount of P gain

P=2

l=0

D=0

With the controller configured in Speed Position mode and the motor stopped,do a first check of the PID’s stiffness by attempting to rotate the motor by hand.It should feel

increasingly hard to rotate away from the rest position.With a higher P gain,it will be- come harder to move than lower gains.As a rule of thumb,on a mobile robot,use a gain that makes it very hard to move the wheel more than a quarter turn away from the rest position.Test then by applying a speed command and verifying the motor runs smoothly under all load conditions.

The l and D gain can generally be omitted in Speed Position mode.

Beware to set speeds that can physically be reached by the motor under load.The Closed Loop Speed Position mode relies on the fact that the motor will actually be able to follow the computed trajectory.If the motor is not able,the controller will pause updating the

destination counter until the motor caught up.This will result in inaccurate speed and can be a problem in mobile robot applications depending on precise control of their left and right side motor.

Closed Loop Speed Mode lRoboteQ
Error Detection and Protection

The controller will detect large tracking errors due to mechanical or sensor failures,and shutdown the motor in case of problem in closed loop speed or position system.The detection mechanism looks for the size of the tracking error (desired position vs.actual position for the close loop speed position and the desired speed vs.actual speed for the close loop speed mode)and the duration the error is present.Three levels of sensitivity are provided in the controller configuration:

1:250ms and Error>100

2:500ms and Eror >250

3:1000ms and Error>500

When an error is triggered,the motor channel is stopped until the error has disappeared or when the motor channel is reset to open loop mode.The error is cleared when a stop command is issued.

Clearing the loop error make the motor available for moving again.However,this does not mean that the loop error will not happen again.Configuration tuning is necessary in order to prevent from having Loop Error again.The loop error value can be monitored in real

time using the Roborun PC utility.

Modes Description

SECTION 11

Closed Loop

Relative and

Tracking Position

Modes

This section describes the controller’s Position Relative and Position Tracking modes,how to wire the motor and position sensor assembly and how to tune and operate the control- ler in these modes.

Modes Description

In these two position modes,the axle of a geared-down motor is coupled to a position sensor that is used to compare the angular position of the axle versus a desired position. The controller will move the motor so that it reaches this position.

This feature makes it possible to build ultra-high torque”jumbo servos”that can be used to drive steering columns,robotic arms,life-size models and other heavy loads.

The two position modes are similar and differ as follows:

Position Relative Mode

The controller accepts a command ranging from-1000 to+1000,from serial/USB,analog joystick,pulse input or CAN command.The controller reads a position feedback sensor

and converts the signal into a-1000 to+1000 feedback value at the sensor’s min and max range respectively.The controller then moves the motor so that the feedback matches the command,using a controlled acceleration,set velocity,and controlled deceleration.This

mode requires several settings to be configured properly but results in very smoothly con- trolled motion.

Position Tracking Mode

This mode is identical to the Position Relative mode in the way that commands and feed- back are evaluated.However,the controller will move the motor simply using a PID com- paring the command and feedback,without controlled acceleration and as fast as possible. This mode requires fewer settings but often results in a motion that is not as smooth and harder to control overshoots.

Closed Loop Relative and Tracking Position Modes lRoboteQ

Selecting the Position Modes

The two position modes are selected by changing the Motor Control parameter to Closed Loop Position.This can be done using the corresponding menu in the Power Output tree in the Roborun utility.It can also be done using the associated serial (RS232/RS485/TCP/ USB)command.See”MMOD”on page 310.The position mode can be set independentty for each channel.

Position Feedback Sensor Selection

The controller may be used with the following kinds of sensors:

· Potentiometers

· Hall effect angular sensors

· Optical Encoders

· Hall sensor in brushless motor

The first two are used to generate an analog voltage ranging from OV to 5V depending on their position.They will report an absolute position information at all times.

Modern position Hall sensors output a digital pulse of the variable duty cycle.These sen- sors provide an absolute position value with high precision (up to 12-bit)and excellent

noise immunity.PWM output sensors are directly readable by the controller and therefore are a recommended choice.

Optical encoders report incremental changes from a reference which is their initial posi- tion when the controller is powered up or reset.Before they can be used for reporting po- sition,the motors must be moved in open loop mode until a home switch is detected and resets the counter.Encoders offer the greatest positional accuracy possible.

Sensor Mounting

Proper mounting of the sensor is critical for an effective and accurate position mode oper- ation.Figure 11-1 shows a typical motor,gear box,and sensor assembly.

FIGURE 11-1.Typical motor/Potentiometer/assembly in Position Mode

The sensor is composed of two parts:

· a body which must be physically attached to a non-moving part of the motor as- sembly or the robot chassis,and

· an axle which must be physically connected to the rotating part of the motor you wish to position.

156 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

Feedback Sensor Range Setting

A gear box is necessary to greatly increase the torque of the assembly.It is also neces- sary to slowdown the motion so that the controller has the time to perform the position control algorithm.If the gearing ratio is too high,however,the positioning mode will be very sluggish.

A good ratio should be such that the output shaft rotates at 1 to 10 rotations per second (60 to 600 RPM)when the motor is at full speed.

The mechanical coupling between the motor and the sensor must be as tight as possible. If the gear box is loose,the positioning will not be accurate and will be unstable,potential- ly causing the motor to oscillate.

Some sensors,such as potentiometers,have a limited rotation range of typically 270

degrees (3/4 of a turn),which will in turn limit the mechanical motion of the motor/poten- tiometer assembly.Consider using a multi-turn potentiometer as long as it is mounted in a manner that will allow it to turn throughout much of its range,when the mechanical assembly travels from the minimum to maximum position.When using encoders,best results are achieved when the encoder is mounted directly on the motor shaft.

Feedback Sensor Range Setting

Regardless of the type of sensor used,feedback sensor range is scaled to a -1000 to +1000 value so that it can be compared with the -1000 to +1000 command range.

On analog and pulse sensors,the scaling is done using themin/max/center configuration parameters

When encoders are used for feedback,the encoder count is also converted into a -1000 to +1000 range.In the encoder case,the scaling uses the Encoder Low Limit and Encoder High Limit parameters.See”Serial (RS232/USB)Operation”on page 161 for details on

these configuration parameters.Beware that encoder counters produce incremental val- ues.The encoder counters must be reset using the homing procedure before they can be used as position feedback sensors.

Important Notice

Potentiometers are mechanical devices subject to wear.Use better quality potenti-

ometers and make sure that they are protected from the elements.Consider using

a solid state hall position sensor in the most critical applications.Optical encoders

may also be used,but require a homing procedure to be used in order to determine the zero position.

Important Warning

If there is a polarity mismatch,the motor will turn in the wrong direction and the position will never be reached.The motor will turn until the Closed Loop Error de-

tection is triggered.The motor will then stop until the error disappears,the control- ler is set to Open Loop,or the controller is reset.

Closed Loop Relative and Tracking Position Modes lRoboteQ
Determining the right polarity is best done experimentally using the Roborun utility (see “Roborun+Utility User Manual”)and following these steps:

1. Configure the controller in Open Loop Speed mode.

2.Configure the position sensor input channel as position feedback for the desired mo- tor channel.

3. Click on the Run tab.

4. Enable the Feedback channel in the chart recorder.

5.Move the slider slowly in the positive direction and verify that the Feedback in the chart increases in value.If the Feedback value decreases,then the sensor is backward and you should either invert using configuration commands,invert the sensor physically,it or swap the motor wires so that the motor turns in the opposite direction.

6. Move the sensor off the center position and observe the motor’s direction of rotation.

7.Go to the max position and verify that the feedback value reaches 1000 a litle before the end of the physical travel.Modify the min and max limits for the sensor input if needed.

8.Repeat the steps in the opposite direction and verify that the -1000 is reached a little before the end of the physical travel limit.

Important Safety Warning

Never apply a command that is lower than the sensor’s minimum output value or higher than the sensor’s maximum output value as the motor would turn forever trying to reach a position it cannot.Configure the Min/Max parameter for the sen- sor input so that a value of -1000 to+1000 is produced at both ends of the sensor travel.

Adding Safety Limit Switches

The Position mode depends on the position sensor providing accurate position informa- tion.If the sensor is damaged or one of its wires is cut,the motor may spin continuously in an attempt to reach a fictitious position.In many applications,this may lead to serious mechanical damage.

To limit the risk of such breakage,it is recommended to add limitswitches that will

cause the motor to stop if unsafe positions have been reached independently of the

sensor reading.Any of the controller’s digital inputs can be used as a limit switch for any motor channel.

Using Current Trigger as Protection

The controller can be configured to trigger an action when the current reaches a user con- figurable threshold for more than a set amount of time.This feature can be used to detect that a motor has reached a mechanical stop and is no longer tuning.The triggered action can be an emergency stop or a simulated limit switch.

Operating in Closed Loop Relative Position Mode

This position algorithm allows you to move the motor from an initial position to the desired position.The motor starts with a controlled acceleration,reaches the desired velocity,

158 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

Operating in Closed Loop Relative Position Mode

and decelerates at a controlled rate to stop precisely at the end position.The graph below shows the speed and position vs.time during a position move.

Position

Acceleration Deceleration

FIGURE 11-2.Position Mode Functionality

When tuning the controller on,the default acceleration,deceleration and velocity are pa- rameters retrieved from the configuration EEPROM.In most applications,these parame- ters can be left unchanged and only change in commands used to control the change from one position to the other.In more sophisticated systems,the acceleration,deceleration

and velocity can be changed on the fly using Serial/USB commands or from within a Mi- croBasic script.

When using Encoders as feedback sensors,the controller can accurately measure the speed and the number of motor turns that have been performed at any point in time.The complete positioning algorithm can be performed with the parameters described above.

When using analog or pulse sensors as feedback,the system does not have a direct way to measure speed or number of turns.It is therefore necessary to configure an additional parameter in the controller which determines the number of motor turns between the

point the feedback sensor gives the minimum feedback value (-1000)to the maximum feedback value(+1000).

In the Closed Loop Relative Position mode,the controller will compute the position at

which the motor is expected to be at every millisecond in order to follow the desired ac- celeration and velocity profile.This computed position becomes the setpoint that is com- pared with the feedback sensor and a correction is applied at every millisecond.

For troubleshooting,the computed position can be monitored in realtime by enabling the Tracking channel in the PC utility’s chart recorder.

Closed Loop Relative and Tracking Position Modes RoboteQ
Beware not to use accelerations and max velocity that are beyond the motor’s physical reach at full load.This would result in a loop error which will stop the system if growing too large.

Operating in Closed Loop Tracking Mode

In this mode,the controller makes no effort to compute a smooth,millisecond by milli- second position trajectory.Instead,the current feedback position is periodically compared with the requested destination and power is applied to the motor using these two values in a PID control loop.

This mode will work best if changes in the commands are smooth and not much faster than what the motor can physically follow.

Position Mode Relative Control Loop Description

The controller performs the Relative Position mode using a full featured Proportional,In- tegral and Differential (PID)algorithm (using the Position Gains).This technique has a long history of usage in control systems and works on performing adjustments to the speed command based on the difference measured between the desired position (set by the user)and the actual position (captured by the position sensor).

Figure 10-4 shows a representation of the PID algorithm.Every 1 millisecond,the control- ler measures the actual motor position and subtracts it from the desired position to com- putethe position error.

The resulting error value is then multiplied by a user selectable Proportional Gain.The result- ing value becomes one of the components used to command the motor.The effect of this part of the algorithm is to calculate the speed command to the motor control that is pro-

portional with the distance between the current and desired positions:when far apart,high speed command is generated,with the power being gradually reduced and stopped as the motor moves to the final position.The Proportional feedback is the most important compo- nent of the PID in Position mode.

If the PID of the speed Pl controller is not configured,then the output of the position PID corresponds to the applied output voltage (power).In this case,it is highly recommended to configure only the flux FOC gains and set the torque FOC gains to zero.

A higher Proportional Gain will cause the algorithm to apply a higher level of speed/

voltage commands for a given measured error,thus making the motor move quicker.Be- cause of inertia,however,a faster moving motor will have more difficulty stopping when it reaches its desired position.It will therefore overshoot and possibly oscillate around that end position.

The Differential component of the algorithm computes the changes to the error from one ms time period to the next.This change will be a relatively large number every time an

abrupt change occurs on the desired position value or the measured position value.The value of that change is then multiplied by a user-selectable Differential Gain and added to the output.The effect of this part of the algorithm is to give a boost of extra power when starting the motor due to changes to the desired position value.The differential compo- nent will also help dampen any overshoot and oscillation.

The Integral component of the algorithm performs a sum of the error over time.In the position mode,this component helps the controller reach and maintain the exact desired position when the error would otherwise be too small to energize the motor using the Proportional component alone.Only a very small amount of Integral Gain is typically re- quired in this mode.

In systems where the motor may take a long time to physically move to the desired

position,the integrator value may increase significantly causing then difficulties to stop without overshoot.The Integrator Limit parameter will prevent that value from becoming unnecessarily large.

PID tuning in Position Mode

As discussed above,three parameters -Position Proportional Gain,Position Integral Gain and Position Differential Gain -can be adjusted to tune the position control algorithm.The ultimate goal in a well tuned PID is a motor that reaches the desired position quickly with- out overshoot or oscillation.

Because many mechanical parameters such as motor power,gear ratio,load and in- ertia are difficult to model,tuning the PID is essentially a manual process that takes experimentation.

Closed Loop Relative and Tracking Position Modes lRoboteQ
The Roborun PC utility makes this experimentation easy by providing one screen for

changing the Proportional,Integral and Differential gains and another screen for running and monitoring the motor.

When tuning the motor,first start with the Integral and Differential Gains at zero,increas- ing the Proportional Gain until the motor overshoots and oscillates.Then add Differential gain until there is no more overshoot.If the overshoot persists,reduce the Proportional Gain.Add a minimal amount of Integral Gain.Further fine tune the PID by varying the

gains from these positions.

To set the Proportional Gain,which is the most important parameter,use the Roborun util- ity to observe the three following values:

· Command Value

· Actual Position

· Actual Speed

With the Integral Gain set to 0,the PID output should be:

PID Output=(Command Value -Actual Position)*Proportional Gain

The PID output can be the speed command or the applied power(voltage),depending on whether the speed gains are set or zeroed respectively.Experiment first with the motor electrically or mechanically disconnected and verify that the controller is measuring the correct position and is applying the expected amount of power (voltage)to the motor de- pending on the command given.

Verify that when the Command Value equals the Actual Position,the Applied Power (Volt- age)equals to zero.Note that the Applied Power {Voltage)value is shown without the sign in the PC utility.

In the case where the load moved by the motor is not fixed,the PID must be tuned with the minimum expected load and tuned again with the maximum expected load.Then try to find values that will work in both conditions.If the disparity between minimal and maxi- mal possible loads is large,it may not be possible to find satisfactory tuning values.

PID Tuning Differences between Position Relative and Position Tracking

The PID works the same way in both modes in that the desired position is compared to the actually measured position.

In the Closed Loop Relative mode,the desired position is updated every ms and so the PID deal with small differences between the two values.

In the Closed Loop Tracking mode,the desired position is changed whenever the com- mand is changed by the user.

Tuning for both modes requires the same steps.However,the P I and D values can be ex- pected to be different in one mode or the other.

Mode

In the Closed Loop Position mode,the controller can move a motor a precise number of counts,using a predefined acceleration,constant velocity,and deceleration.This mode requires that an encoder be mounted on the motor.

Mode description

The desired position is given in the number of counts.Using acceleration,deceleration

and top velocity,the controller computes the position at which the motor is expected to be at every one millisecond interval.A PID then computes the speed to give to the motor in order to maintain that position.A comparator looks at the desired position and the com- puted current position and issues a Destination Reached flag.The figure below shows a representation of this mode.

Closed Loop Count Position Mode RoboteQ
SensorTypes and Mounting

In position mode,best results are achieved with encoders directly mounted on the motor shaft.Encoders can be:

· Quadrature encoders

· Hall Sensors built-in brushless motors

· Other rotor sensors built-in brushless motors

It is not advised to mount encoders at the output of a geared motor as the gear box often introduces backlash.If the encoder must be mounted at the output,then it must typically have a higher count to compensate the lower speed rotation at that location.

Quadrature encoders typically provide the highest resolution since they can be ordered

with a line resolution of several hundred or thousands of counts per revolution.Hall

encoders built in brushless motors give a relatively low,but often adequate count of 6*

NumberOfPoles per mechanical resolution.SSl digital sensors give a pole resolution equal to their SSl sensor resolution.Other brushless rotor sensors,such as sin/cos or resolver

sensors will give up to 512 counts per pole and can therefore be used instead of encoders.

Encoder Home reference

Beware that encoders do not give an absolute position information.It is therefore neces- sary to perform a search of the zero reference position at least once after every power up. This is typically achieved by moving the motor up to a limit switch and loading the counter with a fixed value at that location.A home search sequence can easily be implemented

using a MicroBasic script.The search and counter loading must be done while the motor is operated in an open loop.

SSI Sensor Home reference

When SSl sensors are used as relative encoders,it is as well necessary to perform a search of the zero reference position,as stated above..When SSl sensors are used as absolute en- coders (Absolute Feedbac),Home reference is used as an offset to the SSI Counter.

Important Warning

Changing the counter with value while the motor is operated in a closed loop can cause violent and dangerous jumps.Always revert to open loop to change the counter value.

Preparing and Switching to Closed Loop

To enter this mode you will first need to configure the encoder so that it is used as feed- back for motor1,and feedback for motor2 on the other encoder in a dual motor system. On brushless motors,selecting “Other”in Closed Loop Feedback Sensor,the encoder or the SSl sensor,if either present and property configured,will be used as feedback.Select- ing“Internal Sensor;Hall,sin/cos or resolver sensor,depending on which is configured, will be used as feedback.

Use the PC Utility to set the default acceleration,deceleration,position mode velocity as long as maximum and minimum speed in the motor menu.These values can then be changed on the fly if needed.

166 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

Count Position Commands

While in Open Loop,enable the Speed channel in the Roborun Chart Recorder.Move the slider in the positive direction and verify that the measured speed polarity is also positive. If a negative speed is reported,swap the two encoder wires to change the measured po- larity,or swap the motor leads to make the motor spin in the opposite direction.

Then use the PC Utility to select the Closed Loop Position Mode.After saving to the con- troller,the motor will operate in Closed Loop and will attempt to go to the 0 counter posi- tion.Beware therefore that the motor has not already turned before switching to Closed Loop.Reset the counter if needed prior to closing the loop.

Count Position Commands

Moving the motor is done using a set of simple commands.

To go to an absolute encoder position value,use the !P command

To go to a relative encoder position count that is relative to the current position,use the !PR command.

The Acceleration,Deceleration and Velocity are fixed parameters that can be changed us- ing the ^MAC,^MDEC and ^MVEL configuration settings.These can also be changed on the fly,anytime using the !AC and !DC commands.

The velocity can also be changed at any time using the !S command:

New position destination command can be issued at any time.If the previous destination is not reached while the new is sent,the motor will move to the new destination.If this causes a change of direction,the motor will do the change using the current acceleration and deceleration settings.See the Commands Reference section for details on all these commands

Position Command Chaining

It is possible to chain position commands in order to create seamless motion to a new

position after an initial position is reached.To do this,the controller can store the next goto position with,optionally,a new set of acceleration,deceleration and velocity values.

The commands that set the”next”move are identical to these discussed in the previous section,with the addition of an “X”at the end.The full command list is:

IPX nn mm Next position absolute

!PRX nn mm Next position relative

!ACX nn mm Next acceleration

!DCX nn mm Next deceleration

!SX Next velocity

Closed Loop Count Position Mode lRoboteQ
Example: !PX 1-50000 will cause the motor to move to that new destination

once the previous destination is reached.!PRX -10000 will cause the

motor to move 10000 count back from the previous end destination.If the next acceleration,next deceleration or next velocity are not entered, the value(s)used for the previous motion will be used.

Beware that the next commands must be entered while the motor is moving,since the next commands will only betaken into account at the end of the current motion.

To chain more than two commands,use a MicroBasic script or an external program to load new”next”command when the previous”next”commands become active.The ?DR query can be used to detect that this transition has occurred and that a new next command can be sent to the controller.

The chart below shows a typical chaining flow.

Position Accuracy Considerations

In the position mode,the controller computes a trajectory that the motor then attempts to follow using a PID.For this technique to work well,the motor must first be physically able to run as fast as dictated by the trajectory calculation.If not,a loop error (ie desired posir- tion -actual position)will accumulate and eventually grow to trigger an error that will stop the motor.Make sure that the velocity setting is always under the max speed that can be reached by the motor while running at full load,in open loop.

Some difference between the desired and actual position,i.e.a loop error,is always to be expected when using a PID.The PID gains must be tuned to minimize the loop error while keeping smooth motion.The expected position and loop error can be monitored in realtime using the PC utility’s Tracking and Loop Error channels,respectively,in the chart recorder.

IRoboteQ

PID Tunings

Beware that the Destination Reached flag will become true when the result of the trajec- tory computation equals the desired destination.In most practical situations,the motor will still be on its way to actually reach that destination.This can be an important consid- eration when chaining commands,as the new command will become active before the motor has actually reached the previous destination

PID Tunings

As long as the motor assembly can physically reach the acceleration and velocity,smooth motion will result in relatively little need for tuning.As for any position control loop,the

dominant PID parameter is the Proportional gain with only little Integral gain and smaller or no Derivative gain.See“PID tuning in Position Mode”on page 148.

Loop Error Detection and Protection

The controller will detect large tracking errors due to mechanical or sensor failures,and

shutdown the motor in case of problem in closed loop speed or position system.The

detection mechanism looks for the size of the tracking error (desired position vs.actual po- sition)and the duration the error is present.Three levels of sensitivity are provided in the controller configuration:

1:250ms and Error>100

2:500ms and Error>250

3:1000ms and Error>500

When an error is triggered,the motor channel is stopped until the error has disappeared, the motor channel is reset to open loop mode.The error will also be cleared when send- ing a new Position Destination using the !P command with value equal to actual position (feedback).

The loop error can be monitored in realtime using the Roborun PC utility.

Closed Loop

Torque Mode

This section describes the controller’s operation in Torque Mode.

Torque Mode Description

The torque mode is a special case of closed loop operation where the motor command controls the current that flows through the motor regardless of the motor’s actual speed.

In an electric motor,the torque is directty related to the current.Therefore,controlling the current controls the torque.

FIGURE 13-1.Torque mode

Torque mode is mostly used in electric vehicles since applying a higher command gives more “push”similarly to how a gas engine would respond to stepping on a pedal.Like- wise,releasing the throttle will cause the controller to adjust the power output so that the zero amps flow through the motor.In this case,the motor will coast and it will take a neg- ative command (i.e.negative amps)to brake the motor to a full stop.When the sinusoidal mode is selected,the field oriented current control is utilized,in order to regulate the lq (Torque Amps)and ld (Flux Amps)at the reference values for each kind of motor selected (brushless dc,IPM,Induction).

Closed Loop Torque Mode lRoboteQ
Torque Mode Selection,Configuration and Operation

Use the PC utility and the menu “Operating Mode”to select Torque Mode.The controller will now use user commands from RS232,RS485,TCP USB,Analog or Pulse to command the motor current.

Torque commands can be given:

· G command,with range -1000 to+1000.The command for brushed controllers is then scaled using the amps limit configuration value.For example,if the amps lim- it is set to 100A,a user command of 500 will cause the controller to energize the motor until 50A are measured.For brushless controllers and in sinusoidal mode,

the G command is scaled based on the torque (quadrature)amps limit.If flux amps are always at 0 (no field weakening)then the scaling is the same.

· TC command,which is similar to G command but the command is given in

Nm*100.The torque constant TNM is used in order to translate the torque com- mand to current command.

· GIQ command (applicable only for brushless motor controller and sinusoidal mode), with which one can give the Torque (quadrature)amps command in Amps*10.

· GID command (applicable only for brushless motor controller and sinusoidal mode), with which one can give the Flux amps command in Amps*10.

Torque Mode Tuning

In Torque Mode,the measured Motor Amps become the feedback in the closed loop sys- tem.The PID then operates the same way as in the other Closed Loop modes described in this manual (See”PID tuning in Position Mode”on page 148).

In most applications requiring torque mode,the loop response does not need to be very quick and good results can be achieved with a wide range of PID gains.The P and I gains are the primary component of the loop in this mode.Perform the first test using P=0,l=1 and D=0,and then adjust the l and P gain as needed until satisfactory results are reached. In brushless controllers,torque mode uses the PID that is regulating the Field Oriented

Control,which are the same with Closed Loop Torque PID parameters.See also the KIF and KPF configuration commands in the Commands Reference section.

Configuring the Loop Error Detection

In Torque Mode,it is very likely that the controller will encounter a situation where the

motor is not sufficiently loaded in order to reach the desired amps.In this case,controller output power (voltage)will quickly rise to 100%while a significant Loop Error (i.e.desired amps -measured amps)is present.In the default configuration,the controller will shut

down the power if a large loop error is present for more than a preset amount of time. This safety feature should be disabled in most systems using Torque Mode.

172 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

Torque Mode Limitations

Speed Limiting

All Controllers provide a way of smoothly limiting the speed in torque mode to prevent motor runaways.The method for limiting the speed is based on PID speed override con- trol which provides very smooth motor output but requires PID tuning.

Therefore for the torque loop we use the Torque Proportional Gain (KPF)and the Torque In- tegral Gain (KIF),in Closed Loop Torque parameters,and the speed limit is tuned using the Speed Proportional Gain (KPG),the Speed Integral Gain (KIG)and the Speed Differential Gain {KDG),in Closed Loop Speed parameters.The speed loop PID tuning can either be done in “Closed Loop Torque Mode”at the speed limit or in”Closed Loop Speed Mode” by looking at the response time.

Torque Mode Limitations

The torque mode uses the Motor Amps and not the Battery Amps.See “Battery Current vs.Motor Current”on page 28.In some Roboteq controllers,Battery Amps is measured and Motor Amps is estimated.The estimation is fairly accurate at power level of 20%and higher.Its accuracy drops below 20%of PWM output and no motor current is measured at all when the power output level is 0%,even though current may be flowing in the

motor,as it would be the case if the motor is pushed.The torque mode will therefore not operate with good precision at low power output levels.

Furthermore the resolution of the amps capture is limited to around 0.5%of the full range. On high current controller models,for example,amps are measured with 500mA incre-

ments.If the amps limit is set to 100A,this means the torque will be adjustable with a 0.5% resolution.If on the same large controller the amps limit is changed to 10A,the torque will be adjustable with the same 500mA granularity which will result in 5%resolution.For best results use an amps limit that is at least 50%than the controller’s max rating.On newer

Brushless motor controllers,amps sensors are placed at the motor output and motor amps are measured directly.Torque mode will work effectively on these models.

SECTION 14

Serial (RS232/

RS485/USB/TCP)

Operation

This section describeshow to communicate to the controller via the RS232,RS485,USB or TCP Interface.This information is useful if you plan to write your own controlling soft- ware on a PC or microcomputer.

The full set of commands accepted by the controller is provided in “Commands Refer ence”on page 169.

If you wish to use your PC simply to set configuration parameters and/or to exercise the controller,you should use the RoborunPlus PC utility.

Use and benefits of Serial Communication

The serial communication allows the controller to be connected to PCs,PLC,microcom-

puters or wireless modems.This connection can be used to both send commands and

read various status information in real-time from the controller.The serial mode enables

the design of complex motion control system,autonomous robots or more sophisti-

commands are very precise and securely acknowledged by the controller.They are also

the method by which the controller’s features can be accessed and operated to their

fullest extent.

When operating in RC or analog input,serial communication can still be used for monitor ing or telemetry.

When connecting the controller to a PC,the serial mode makes it easy to perform simple diagnostics and tests,including:

· Sending precise commands to the motor

· Reading the current consumption values and other parameters

· Obtaining the controller’s software revision and date

· Reading inputs and activating outputs

· Setting the programmable parameters with a user-friendly graphical interface ·Updating the controller’s software

Serial (RS232/USB)Operation

Serial Port Configuration

The controller’s default serial communication port is set as follows:

· 115200 bits/s

· 8-bit data

· 1 Start bit

· 1 Stop bit

· No Parity

Communication is done withoutflow control,meaning that the controller is always ready to receivedata and can send data at any time.

Connecting to Arduino and otherTTL Serial Microcomputers

Arduino and similar microcomputers have a TTL serial port.There are Roboteq controllers supporting RS485,so the connection can be done directly.However,for the rest of the controllers there is a full RS232 serial interface.RS232 has the following differences from TTL serial:

TABLE 14-2.Connecting with TTL devices

RS232 TTL Serial
Voltage Levels +10V/-10V 0-3V
Logic level Inverted Non-Inverted

ATTL to RS232 adapter must be therefore be used to convert to the Arduino serial inter- face.Newer Roboteq controller allows the RS232 signal to be non-inverted.Intertacing to Arduino or other TTL Serial interface can therefore be done with just a resistors,and 2 optional diodes as shown in the diagram below:

178 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

Connecting to Arduino and other TTL Serial Microcomputers

FIGURE 14-4.Simplified TTL to RS232 connection

TxD RxD

The data sent from the TTL serial port are 0-3V and can be directly connected to the con- troller’s RS232 input where it will be captured as valid O-1 levels.

The data at the output of the controller is +/-10V.At the other end of the resistor,the

voltage is clamped to around O-3.3V by the protection diodes that are included in the AF duino MCU.However,to avoid any stress it is highly recommended to insert the 2 diodes shown on the diagram.

To operate,the RS232 output must be set to inverted.This must be done from the Con-

sole of the Roborun Utility while connected via USB.This will only work on newer control-

ler models fitted with firmware version 1.6a or more recent.

From the Console,send the following commands:

Make sure that the controller respond to this command with a +.Check that the value has been accepted by sending ~RSBR.If a-is replied or if the value is different than the one entered,then the hardware and/or firmware does not support serial inverted and cannot be used with this circuit.

RS485 Configuration

Consult your controller’s datasheet in order to know whether RS485 communication is supported.There are controller models whose pins related to RS485 communication are shared with other functionalities (check the controller’s datasheet).For this reason for

these controllers only,the RS485 functionality is by default disabled.In order to enable it the RS485 configuration command (RS485 enable)should be set to 1 (^RS4851).

USB Configuration

USB is available on all Roboteq controller models and provides a fast and reliable commu- nication method between the controller and the PC.After plugging the USB cable to the controller and the PC,the PC will detect the new hardware,and install the driver.Upon successful installation,the controller will be ready to use.

The controller will appear like another Serial device to the PC.This method was selected because of its simplicity,particularly when writing custom software:opening a COM port and exchanging serial data is a well documented technique in any programming language.

Note that Windows will assign a COM port number that is more or less random.The Rob- orun PC utility automatically scans all open COM ports and will detect the controller on its own.When writing your own software,you will need to account for this uncertainty in the COM port assignment.

Important Warning

Beware that because of its sophistication,the USB protocol is less likely to recover than RS232 should an electrical disturbance occur.We recommend using USB for

configuration and monitoring,and use RS232 for field deployment.Deploy USB

based system only after performing extensive testing and verifying that it operates reliably in your particular environment.

TCP Configuration

Controller models that support communication via an Ethemet cable are identified with

the letter E,for example,FBL2360E or FBL2360ES.By default,TCP communication is

disabled on controllers,so in order to use this feature configuration is needed.All configu- ration parameters may be accessed under the Roborun+Configuration tab.All TCP param- eters are configurable from the TCP node under the Inputs/Outputs Column.Find more

FIGURE 14-6.TCP configuration

AIITCP/IP configuration changes will be applied within one second after activation and

communication via TCP Modbus TCP or Modbus TCP over RTU will be available as long as the TCP mode is enabled.

Command Priorities

The controller will respond to commands from one of five possible sources:

· CAN or Script Command

· Serial (RS232,RS485,TCP or USB)

· Pulse

· Analog

· Spektrum Radio (when available)

One,two,three or four (except from CAN or Script command,which is always enabled) command modes can be enabled at the same time.When multiple modes are enabled, the controller will select which mode to use based on a user selectable priority scheme. The priority mechanism is described in details in “Input Command Modes and Priorities” on page 73.

Communication Arbitration

Commands may arrive through the RS232,RS485,TCP or the USB port at the same time. They are executed as they arrive in a first come first served manner.Commands that are arriving via USB are replied on USB.Commands arriving via the UART are replied on the UART.Redirection symbol for redirecting outputs to the other port exists (e.g.a command can be made respond on USB even though it arrived on RS232).

Serial (RS232/USB)Operation

lRoboteQ

CAN Commands

Commands arriving via CAN have bigger priority than serial commands and will not con- flict with motor command arriving via serial,TCP or USB.CAN commands are also subject to the serial Watchdog timer.Motors will be stopped and command input will switch ac- cording to the Priority table if the Watchdog timer is allowed to timeout.

Script-generated Commands

Commands that are issued from a user script have bigger priority than serial and CAN

commands and will not conflict with motor command arriving via serial,TCP USB or CAN. Script commands are also subject to the serial Watchdog timer.Motors will be stopped and command input will switch according to the Priority table if the Watchdog timer is al- lowed to timeout.

Communication Protocol Description

The controller uses a simple communication protocol based on ASCll characters.Com- mands are not case sensitive.?a is the same as ?A. Commands are terminated by car- riage return (Hex Ox0d,v’).

The underscore’_character is interpreted by the controller as a carriage return.This alter- nate character is provided so that multiple commands can be easily concatenated inside a single string.

All other characters lower than Ox20 (space)have no effect.

Character Echo

The controller will echo back to the PC or Microcontroller every valid character it has re- ceived.If no echo is received,one of the following is occurring:

· echo has been disabled

· the controller is Off

· the controller may be defective

Command Acknowledgment

The controller will acknowledge commands in one of the two ways:

For commands that cause a reply,such as a configuration read or a speed or amps que- ries,the reply to the query must be considered as the command acknowledgment.

For commands where no reply is expected,such as speed setting,the controller will issue a”plus”character (+)followed by a Carriage Return after every command as an acknowl- edgment.

Command Error

If a command or query has been received,but is not recognized or accepted for any rea- son,the controller will issue a”minus”character (-)to indicate the error.

182 Advanced Digital Motor Controller User Manual V2.1 December 3,2020

IRoboteQ

Raw Redirect Mode

If the controller issues the”-“character,it should be assumed that the command was not recognized or lost and that it should be repeated.

Watchdog time-out

For applications demanding the highest operating safety,the controller should be config- ured to automatically switch to another command mode or to stop the motor (but other- wise remain fully active)if it fails to receive a valid command on its RS232,RS485,TCR USB or CAN ports,or from a MicroBasic Script for more than a predefined period.

By default,the watchdog is enabled with a timeout period of 1 second.Timeout period can be changed or the watchdog can be disabled by the user.When the watchdog is en- abled and timeout expires,the controller will accept commands from the next source in the priority list.See Command Priorities on page 167.

Controller Present Check

The controller will reply with an ASCll ACK character (0x06)anytime it receives a QRY character (0x05).This feature can be used to quickly scan a serial port and detect the

presence,absence or disappearance of the controller.The QRY character can be sent at any time (even in the middle of a command)and has no effect at all on the controller’s normal operation.

Raw Redirect Mode

In the Raw Redirect mode,received unprocessed data coming from either RS232 or

RS485 interfaces,can be read by the user.Likewise,the user can send data with any

content towards either RS232 or RS485 interfaces.The data are split into frames.In ASCll mode one frame is the sequence of characters ending with a termination character (v). In RTU mode one frame is defined based on the Modbus RTU regulations (after specific silent time goes by,see Modbus Manual for more details).

Configuration

Raw Redirect mode is enabled for either RS232 or RS485 interfaces using the Raw Redi- rect Mode (see ISM-Raw Redirect Mode,in page 300)configuration command.By de-

fault ASCll mode is used,however if the respective Modbus Mode (see DMOD-Modbus Mode,in page 298)is set to RTU then the received data will be handled according to the Modbus RTU regulations (See Modbus Manual for more details).

Checking Received Frames

Received frames are first loaded in the 256-byte FIFO buffer.Before a frame can be read, it is necessary to check if any frames are present in the buffer using the ?CD query.The query can be sent from the serial/USB port,or from a MicroBasic script using the getval- ue(_CD)function.The query will return the number of frames that are currently pending, and copy the oldest frame into the read buffer,from which it can then be accessed.Send- ing ?CD again,copies the next frame into the read buffer.

The query usage is as follows:

RoboteQ

Serial (RS232/USB)Operation

Syntax:?CD

Reply:CD=number of framespending

Reading Received Frames

After a frame has been moved to the read buffer,the byte size and the data can be read with the ?DDT query.The query can be sent from the serial/USB port,or from a MicroBa- sicscnipt using the getvalue(_DDT,n)function or getvaluel(_SDT,n)function for ASCll

mode.The query usage is as follows:

Syntax:?DDT lee]

AC-Set Acceleration

Alias:ACCEL HexCode:07 CANOpen id:0x2006

Description:

Set the rate of speed change during acceleration for a motor channel.This command is

identical to the MACC configuration command but is provided so that it can be changed

rapidly during motor operation.Acceleration value is in 0.1*RPM per second.When using controllers fitted with encoder,the speed and acceleration value are actual RPMs.Brush- less motor controllers use the hall sensor for measuring actual speed and acceleration will also be in actual RPM/s.When using the controller without speed sensor,the acceleration value is relative to the Max RPM configuration parameter,which itself is a userprovided number for the speed normally expected at full power.Assuming that the Max RPM pa- rameter is set to 1000,and acceleration value of 10000 means that the motor will go from 0 to full speed in exactly 1 second,regardless of the actual motor speed.In Closed Loop Torque mode acceleration value is in 0.1*miliAmps per second.This command is not

applicable if either of the acceleration (MAC)or deceleration (MDEC)configuration value is set to 0.

Runtime Queries

Runtime queries can be used to read the value of real-time measurements at any time

during the controller operation.Real-time queries are very short commands that start with “?”followed by one to three letters.In some instances,queries can be sent with or with- out a numerical parameter.

Without parameter,the controller will reply with the values of all channels.When a nu-

merical parameter is sent,the controller will respond with the value of the channel select- ed by that parameter.

Example:

Q:?T

R: T=20:30:40

Q: ?T2

R:T=30

All queries are stored in a history buffer that can be made to automatically recall the past 16 queries at a userselectable time interval.See”Query History Commands”on page 19Z

Routine queries can be sent from within a MicroBasic Script using the getvalue()function.

V-Read Volts

Alias:VOLTS HexCode:0D CANOpen id:0x210D

Description:

Reports the voltages measured inside the controller at three locations:the main battery voltage,the intemal voltage at the motor driver stage,and the voltage that is available on the 5V output on the DSUB 15 or 25 front connector.For safe operation,the driver stage voltage must be above 12V.The 5V output will typically show the controller’s internal

regulated 5V minus the drop of a diode that is used for protection and will be in the 4.7V range.The battery voltage is monitored for detecting the undervoltage or overvoltage con- ditions.

Query History Commands

Every time a Real Time Query is received and executed,it is stored in a history buffer

from which it can be recalled.The buffer will store up to 16 queries.If more than 16 que- ries are received,the new one will be added to the history buffer while the firsts are re- moved in order to fit the 16 query buffer.

Queries can then be called from the history buffer using manual commands,or automati- cally,at user selected intervals.This feature is very useful for monitoring and telemetry.

RoboteQ

Commands Reference

Additionally,the history buffer can be loaded with a set of user selected queries at power on so that the controller can automatically issue operating values immediately after power up.See “TELS-Telemetry String”configuration command for details on how to set up

the startup Telemetry string.”Another feature is the streams.In this case the data can be printed after a prefix and separated with a delimiter.In order to enable a stream,the spe- cial character “/”needs to be typed in front of the first query.

A command set is provided for managing the history buffer.These special commands start with a“#”character.

Query History Commands

#nn -Start Automatic Sending

This command will initiate the automatic retrieving and execution of queries from the

history buffer.The number that follows the command is the time in miliseconds between repetition.A single query is fetched and executed at each time interval.

Syntax:

#nn

Reply: QQ at every nn time intervals

Where:

QQ =is reply to query in the buffer.

nn = time in ms

Range: nn = 1to 32000ms

#xx nn -Start automatic sending for specific stream

Using this syntax one can set the refresh rate of each stream.This is used only in case of using streams.

Syntax:

#xx nn

Reply:The respective stream at every nn ms.

Where:

xx =the stream.

nn = time in ms.

/?Q cc-Create data streams

Using this syntax the next queries that are going to be sent will be printed after a prefix and separated by a delimiter.The default prefix is none and the default delimiter is tab.

There can be created up to 3 streams and can have different refresh rates.

Syntax:

/”<prefix>””<delimiter”?Q cc

Reply:The regular reply of the query ?Q cc.

Set/Read Configuration Commands

These commands are used to set or read all the operating parameters needed by the con- troller for its operation.Parameters are loaded from EEPROM into RAM,from where they are and then used every time the controller is powered up or restarted.

Important Notices

The total number of configuration parameters is very large.To simplify the config- uration process and avoid errors,it is highly recommended to use the RoborunPlus

PC utility to read and set configuration.

Some configuration parameters may be absent depending on the presence or ab- sence of the related feature on a particular controller model.

Setting Configurations

The general format for setting a parameter is the”A”character followed by the command name followed by parameterls)for that command.These will set the parameter in the con- troller’s RAM and this parameter becomes immediately active for use.The parameter can also be permanently saved in EEPROM by sending the %EESAV maintenance command.

Some parameters have a unique value that applies to the controller in general.For exam- ple,overvoltage or undervoltage.These configuration commands are therefore followed by a single parameter:

AUVL 100:Sets Undervoltage limit to 10.0V

^OVL 400:Sets Overvoltage limit to 40.0V

Other parameters have multiple value,with typically one value applying to a different chan- nel.Multiple value parameters are numbered from 1 to n.For example,Amps limit for a motor channel or the configuration of an analog input channel.

AALIM 1250:Sets Amps limit for channel 1 to 25.0A

AAMIN 42000:Sets low range of analog input 4 to 2000

294 Advanced Digital Motor Controller User Manual V2.1,December 3,2020

IRoboteQ

General Configuration and Safety

Using O as the first parameter value will cause all elements to be loaded with the same content.

AADB 010:Sets the deadband of all analog inputs to 10%

Important Notice

Saving configuration into EEPROM can take up to 20ms per parameter.The controller will suspend the loop processing during this time,potentially affecting the controller operation.Avoid saving configuration to EEPROM during motor operation.

Reading Configurations

Configuration parameters are read by issuing the”~”character followed by the command name and with an optional channel number parameter.If no parameter is sent,the con- troller will give the value of all channels.If a channel number is sent,the controller wil

give the value of the selected channel.

The reply to parameter read command is the command name followed by”=”followed by the parameter value.When the reply contains multiple values,then the different values are separated by”:”The list below describes every configuration command of the control- ler.For Example:

~ALIM:Read Amps limit for all channels

Reply:ALIM=750:650

~ALIM 2: Read Amps limit for channel 2

Reply:ALIM=650

Configuration parameters can be read from within a MicroBasic script using the getcon- fig0 function.The setconfig0 function is used to load a new value in a configuration pa- rameter.

Important Warning

Configuration commands can be issued at any time during controller operation.

Beware that some configuration parameters can alter the motor behavior.Change configurations with care.Whenever possible,change configurations while the

motors are stopped.

Configuration Read Protection

The controller may be locked to prevent the configuration parameters to be read.Given the large number of possible configurations,this feature provides effective system-level copy protection.The controller will reply to configuration read requests only if the read protection is unlocked.If locked,the controller will respond a”-“character.

General Configuration and Safety

The commands in this group are used to configure the controller’s general and safety settings.

MAC -Motor Acceleration Rate

HexCode:33

Description:

Set the rate of speed change during acceleration for a motor channel.This command

is identical to the AC realtime command.Acceleration value is in 0.1*RPM per second.

When using controllers fitted with encoder,the speed and acceleration value are actual

RPMs.Brushless motor controllers use the intermal sensor (Hall,Sin/Cos or Resolvery

for measuring actual speed and acceleration will also be in actual RPM/s.When using

the controller without speed sensor,the acceleration value is relative to the Max RPM

configuration parameter,which itself is a userprovide number for the speed normally

expected speed at full power.Assuming that the Max RPM parameter is set to 1000,and acceleration value of 10000 means that the motor will go from 0 to full speed in exacthy 1 second,regardless of the actual motor speed.If value is set to O then the command ramp is by-passed.
