STM32 MCUs Motor control

Hello,I try to use the NUCLEO-H753ZI in combination with the Motor Control WorkBench 6.2.0.Unfortunately, the bord isn’t supported out of the box now.My experiments to define a new bords runs in several errors.Is there a way to use the STM32H753ZI with the Motor Control WorkBench?Regards

Hello all.I am new to motor controllers and have some questions as I try to understand drivers for BLDCs.I am looking to drive a compressor (using BLDC motor driver).  I require up to 400V at about 2.5A (so 1000W max power).It seems that I could do this with the above board and of course a 400V, 1000W AC/DC power supply.Can someone confirm that this is possible as stated?  Will I be able to change the PWM on the code on the eval board to accomplish this? (I want to be able to run the compressor from 100V to 400V and also shut it off)One final question for evaluation purposes is there a simple windows application for configuration and getting the various voltages out of the device?Thank youSteve 

Still facing problem in STEVAL-SPIN3201. I  got errors like FOC  duration and software error. unable to start the motor. May i know what is the problem?I decreased PWM frequency, changed the execution rate, changed the PID values. Still the errors are there. Please let me know. I attached snapshot for reference.

Hi everyone,Recently I bought a couple of Nucleo-IHM03A1 PowerStep01 Evaluation Boards. I am planning to use these to run a wheel, that will move a body on a rail. The movement needs to be precise, so I decided to go with an Stepper Motor. The motor I choose is RMCS-1004 (which is a NEMA34 Motor with 6A coil ratings). I am supplying the IHM03A1 board with 24V DC from a 24V 5A Adapter. I have mounted the Expansion board on a Nucleo-F030R8 that I had laying around.My problem is as follows:I am not able to run the motor when I send SPI command about the same.The command i am sending is {0x41, 0x00, 0x0F, 0xA0). Which is derived as follows:Move Address: 0100000x (x being direction). This is followed by number of steps to be moved which are 22 bits. I want the stepper to move 4000 steps, so 0x000FA0.I am attaching my code for reference. Please guide me where I am at fault. P.S. I tried using almost similar command to the given STM example code, but it did'nt work. I have tried man

Is STEVAL-SPIN3201 supports six-step or FOC commutation?

Hello,I'm very biginner.By MCSDK6.2, I generated code and tried to spin 3 phases BLDC motor with code" MC_PrgramSpeedRampMotor1(1725, 2000);" and"MC_Startmotor1();"I inserted these code and built and tried to run, but it didn't work.The motor didn't spin, don't move at all.What's the problems ?Also, Cube IDE showed me as below captured photo.What's the reason, is there any problems ? Best Regards,Bryan

Hi, I encountered a problem while trying to control servo motor(SG90) with my custom STM32G030C8T6 board. Servo is not moving at all and only buzzing quietly. I am supplying servo from 5V, board and servo have same GND. I checked servo power supply with potentiometer and voltage seems good. I designed power supply to be able to work with 3A so it should not be a problem either. At first I thought there was a problem with frequency of generated PWM signal (servo is working with 50Hz) but I cannot see any mistake in calculations. APB freq is set to 16MHz. I've tried many combinations of prescaler and ARR values (16-1 prescaler and 20000-1 ARR for example) none of it worked. I have tried with other servos and every try failed. I would be very grateful if someone has any ideas how to deal with this problem.  

HI I have a motor which I've used for while with many 6-step controllers, including commercial ESCs. I profiled this motor and it works well with the ST sensorless FOC, but using the same motor profile in a 6-step app gives very bad results, the motor works OK at low RPM, but above 1K or so it makes a terrible squeeling sound and operates very inefficiently.. I had a quick look at the scope but nothing jumped out at me A couple other Qs:-Where in the MCW config do I configure the PWM input control? -Is there an example of controlling the speed with the Potentiometer on the B-G431B-ESC1 Motor control workbench Version: 6.2.0STM32CubeMX Version: 6.10.0STM32CubeIDE Version: 1.14.0Controler/Driver: B-G431B-ESC1 kitMCW application: Electronic speed control on B-G431B-ESC1 kit (6Step) 

I've purchased a B-G431B-ESC1 kit and loaded it up with software (Details below)and soldered Phase, Power, and PWM/+5/Gnd wires.A couple problems and questions: -On most of my motors, there is no motion produced just some clicks, even though I've matched up motor parameters I think (Is there a way to find motor parameters?).  -On one gimbel motor with higher phase resistance(17ohm), I'm able to get it spinning, but it only spins for a second or 2 then stops, rather than keep going and have speed constantly adjusted. -I am sending a ~490Hz PWM signal with period between, 800us and 2000us (if I don't do this, the controller just sits ther and beeps -Is there a program availabe which just does standard 6-step commuctation without FOC? -Can I run the MotorPilot app without the 490Hz WPM?  Motor control workbench Version: 6.2.0STM32CubeMX Version: 6.10.0STM32CubeIDE Version: 1.14.0 Controler/Driver: B-G431B-ESC1 kit MCW application: Electron

However I can't repeat the operation even with a new project.I don't know what can be change in MC motorbench which can impact the motor profiler SCC.  [EXPECTED BEHAVIOR]:  Project should work either if the option o

Hello, I've made a custom card and I'm stuck on two features in particular:- over-current protection- Current sensingThey don't show up in the ST Workbench Pannel. [VERSION]: 6.1.2[TOOL]: MC WB[DETAILS]:here is an extract of my custom board  (current Sensing):   { "name": "CurrentSensing", "type": "CurrentSensing", "tRise": 59, "hwVariants": [ { "type": "SingleShunt_AmplifiedCurrents_noOffset", "shuntResistor":0.0005, "opAmpGain":20, "amplifyingNetworkImax":330, "amplifyingNetworkVm":3.3, "amplifyingNetworkPrating":10, "signals": { "CURRENT_AMPL": [ { "name": "PA3", "help": "", "cost": 0 } ] } } ] } And for overcurrent protection :  { "name":"OverCurrentProtection", "type":"OverCurrentProtection", "hwVariants": [ { "type":"SingleInput_RawCurrents_Protection_IntRef", "OCNetworkGain":20, "OCNetworkOffset":0, "OCComparatorThreshold":2, "OCSignalPolarity": "Active high", "signals": { "CURRENT_INPUT_P":[ { "name":

i am getting warning when i start the profiler 

All I want to do (for now) is build the ESC software and download it into the B-G431B-ESC1 board.1. After alot of searching, I installed this: MC_SDK_6.2.02.  I ran MotorControl Workbench 6.2.0, loaded the "Electronics Speed control on B-G431B-ESC kit", Click "Generate the Project"3. I get error: STM32CubeMX not found - ver. "6.0.0" or higher is required4. I install STM32Cube 6.1, and also it's "patch" (which the instructions for applying are extremely confusing) Well, that didn't help. I installed STM32CubeMX , tried again and I see the same thing: Logfile from my project:2023-12-06 02:36:22,256 DEBUG [WB_to_MX.lambda$run_gui_mode$0] Arguments: [-mx_timeout, -1, -pack, assets/MotorControlPack/MotorControl.zip, -exp, templates/wb-defines_where_and_what.txt, -ftl, templates/wb_ioc_template.ftl, -xdm, C:\develop\st_workbench\ElectronicSpeedControl_ESC-G4\ElectronicSpeedControl_ESC-G4.wbdef, -ioc, C:\develop\st_workbench\ElectronicSpeedControl_ESC-G4\Electron

I am quite a bit dissapointed, that it is not enough to have the following things:- datasheet- reference manual- application note 4013 "cross-series timer overview"- cubeMX configuration tooland not beeing able to use them together, to set up the hall or quadrature sensor feature.Maybe there are more datasheets and/or software tools needed?From the reference manual alone, i could probably do it, but then, what is the cubeMX software for anyway?It should take only a few clicks and few seconds to set this up. Or is this only in a commercial version?Or does the problem sit in front of the screen? 

Is STEVAL-SPIN3201 supports six-step or FOC commutation ?

Sir i am now working on STEVAL-SPIN3201 evaluation board having 6-step commutation method. I'm unable to rotate motor. I got errors like FOC duration and Software error. I also increased the execution rate one by one . still the motor is not rotating. I attached snapshot for reference. Kindly let me know

Hi,My custom board has an STM32G474RE with an RS-485 port that I would like to use to communicate with the Motor Pilot software. Is it possible? I tried to use the STM32CubeMX to activate the UART5 hardware flow control (DE) but the connection failed.

Everything works fine with my cubeIDE installation.I have cubeMX 6.8.0 installed...

Hello everyone I am looking for some support with using 2 encoders on an STM32F303CB. I am able to select in the Motor Control workbench to have an encoder on Tim3 (pins B4 and B5) or on Tim2 (pins A5 and B3). I need to use 2 encoders for a project. Is there a way to enable encoders on both of these at the same time? 

Hi,We are using MCSDK_v5.Y.4. We would like to implement Stall Detection and are considering using the measured iq current (used in FOC) for detecting a motor stall. We intend to use a Stall_Detection_Threshold, which is just below the "Current_Limit" to detect when the iq current exceeds this threshold for a given duration of time: stall_time. We would like to know if the following function, TSK_MF_StopProcessing(), is recommended to use for stopping the motor, /** * @brief Performs stop process and update the state machine.This function *    shall be called only during medium frequency task */void TSK_MF_StopProcessing( MCI_Handle_t * pHandle, uint8_t motor){#ifdef REV_1 R3_2_SwitchOffPWM(pwmcHandle[motor]);#else ICS_SwitchOffPWM(pwmcHandle[motor]);#endif FOC_Clear(motor); MPM_Clear((MotorPowMeas_Handle_t*) pMPM[motor]); TSK_SetStopPermanencyTimeM1(STOPPERMANENCY_TICKS); Mci[motor].State = STOP;

[VERSION]: MCSDK 6.1.2 and 6.2.0.[TOOL]: MC Workbench, MC Pilot, MC Firmware.[DETAILS]:I developed a control/power board, a custom Hall sensors board and a motor (which will interface a reduction drive) for AGV application. I was able to integrate very well with both versions of the SDK (6.1.2 and 6.2.0). As a start point, it is perfect if you understand how to use it, as it reduces development time of well-known algorithms. I was able to test boards + motor without any problems, at full load, all protections are working, and I checked that current measurement is clean (after adjust the parameters) - not in no-load situation, but this is not a problem as the motor will never run in this situation and noise is expected given measurement range. Given the complexity and requirements of the SDK, the entire application was developed in the while(1) loop, without interruptions, and it runs every 25ms. The problems I am facing relate to 2 situations, both with or without adding the user appli
