STM32 MCUs Motor control

Hello Folks,I am facing an issue while controlling a BLDC motor using the STEVAL-ESC002V1 board. ST provides a reference firmware for this board which includes the 6Step Library for motor control. The firmware exposes functions such as:MC_StartMotor()MC_StopMotor()MC_Set_Speed()According to the documentation, these APIs should allow setting and controlling the motor speed.I had paste the code which is written by me in main while loop. (For Reference)ISSUE:1. when the val(ADC value) goes above the 300, still the MC_StartMotor(), is not getting enable. Motor didn't run.2. If I make changes into my code, delete by everything in the while loop and just try to run the motor at 10000rpm, by function MC_StartMotor() and MC_Set_Speed(10000).As result of it as motor make a sound and vibration, not working smoothly.hey it would be helpful to me, if someone help me to resolve this issue./* Includes ------------------------------------------------------------------*/ #include "main_32F0.h" #includ

Hi there,I have a DIY board similar to EVSPIN32G4. Below is the three-shunt sensing circuit(In internal OpAmps, differential, external gain mode)Because the STSPING4 doesn't support internal OpAmps, differential, external gain mode, I just use the below config to generate the project(seems differential or single-end does not influence the code, yes?), see the project in the attachment:  And because the EVSPIN32G4 project's encoder and hall sensor use the same GPIO, I only enable the encoder in the MCSDK project.After generating the code, I added the hall signal pin in STM32CubeMx and then compiled the MDK project successfully.I added some code trying to find out why the motor isn't working:uint8_t MC_GetHallValM1(void) { uint8_t M_Hall_val; M_Hall_val = (M_Hall_val & 0xFE) | HAL_GPIO_ReadPin(M_HALL_U_GPIO_Port, M_HALL_U_Pin); M_Hall_val = (M_Hall_val & 0xFD) | (HAL_GPIO_ReadPin(M_HALL_V_GPIO_Port, M_HALL_V_Pin) << 1); M_Hall_val = (M_Hall_val & 0xFB

Hello,I'm currently using eval boards B-G473E-ZEST1S + STEVAL-LVLP01 to evaluate a new MCU for brushless motor control. I'm using MotorControl 6.4.1 to generate the firmware project and MotorPilot 6.4.1 to profile and pilot our motor.I've used the interface in MotorControl to create/configure the motor I want to use with my tests. Everything works fine until I push the start button in MotorPilot : I immediately get a FAULT_OVER / Over Current.My brushless motor parameters are the following :Vnominal = +24VMax Speed = 17 000 rpmPole pairs = 2Max nominal current = 9.21 ARs = 0.1 OhmSpeed constant = 710 rpm/VI'm pretty sure there is something I'm not doing right when configuring the motor or when starting the motor control process. Do you have any ideas about what I'm missing ?

Hello! I saw in the release notes for MCSDK 6.4.0 that there is an "Added new Maximum Modulation Index (MMI) computation compatible for all sensor-less or sensor algorithms." How should I use overmodulation on the HSO?

I am trying to spin a new motor with motor pilot using EVSPIN32G4. I am not able to run it. Hitting startup failure.Is there any quick and easy tuning guide available to tune a new motor and run smoothly? 

  i installed x-cube sdk  then  i wanted to make project for an example but even tough i installed last version of cube mx program but i am taked that things all the time thanks for your help.

Hi everyone,I am using the IHM07M1 inverter board to run a PMSM motor, and I need to measure the phase current using the low-side shunt resistor. Currently, I configured the ADC in injected mode and trigger it from a timer event on the falling edge of the PWM.I have a few doubts:Is triggering the ADC on the PWM falling edge the correct method for accurate low-side current sampling?Since current flows through the low-side shunt only when the low-side MOSFET is ON, should I trigger the ADC only during the low-side ON time, or is it valid to sample at any moment in the PWM cycle?I am using Timer1 with 3 channels for PWM generation, and Channel 4 (CH4) as a compare channel to trigger the injected ADC.What value should I assign to OCxREF4 for correct sampling timing?I’m confused about how to choose the right compare value inside the PWM period. If anyone has experience with this setup, please share your guidance. Thanks!

[VERSION]: MCWB v6.3.2[TOOL]: STM32CubeMX v6.13.0, STM32CubeIDE v1.11.5[BOARD]: STEVAL-PTOOL1V1[PROJECT]: STEVAL-PTOOL1V1_6S_SL and STEVAL-PTOOL1V1_6S_HLWhen I run the STEVAL-PTOOL1V1_6S_SL project generated by STM32CubeMX, the program loads and runs as expected.   When I run the STEVAL-PTOOL1V1_6S_HL (which is just the Hall-effect version instead of the sensorless SL version), the program loads and runs when the debugger is connected, but would not run properly after a power cycle, unless I reset the chip using NRST.  Both were tested on the same PCB.I thought the program wasn't booting, but determined that it actually was, but it just wasn't getting past some of the init functions (I think the MX_MotorControl_Init call).  If I add a delay (~1s) after the HAL_Init() and SystemClock_Config() calls, before the other peripheral init calls are made, the program runs normally after a reboot for the most part.  I still see som

Hello,I saw that some people had a similar problem to mine. When generating the project on MC Workbench I have the following error: STM32CubeMX not found - ver. "6.0.0" or higher is requiredBut I have STM32CubeMX installed with version 6.14.0I tried to install STM32CubeMX for all users or to change the Windows language to English as I saw on other posts but without success.Does anyone have another suggestion? Here are some various screenshots that have been asked in similar posts   Thanks for your help !

Hi, I wanted to ask a question about brushless and MCSDK motors. When buying a motor, inertia is often listed, but friction isn't. Can I calculate friction using inertia, or is friction a parameter that can be omitted?

Hi,I’m trying to generate code for a dual-BLDC FOC setup using an STEVAL-IHM039V1 together with two X-NUCLEO-IHM08M1 boards in MC Workbench 6.4.1.For this combination you need an adapter board to go from the motor-control connector to the Morpho connector.As far as I understand, there is no dedicated adapter board for this configuration, but it looks like the X-NUCLEO-IHM09M2 could be used when using double-sided equal length male headers and stacking the IHM08M1 on top of it.However, MC Workbench doesn’t allow me to insert the adapter board between the two boards. When I click “Add adapter”, the page stays empty.Is there any straightforward way to still define this connection inside MC Workbench? Maybe by editing the adapter JSON file or another configuration file? Or will there still be compatibility issues later on when generating the code?Thanks.

Since Updating to new Version is always a lot of manual work i would kindly ask for a Change Log compared to the Major Version 6.4.0.The new Features / Improvements may justify/not justify the move from 6.4.0 -> 6.4.1.

Hello, Does ST have a tentative roadmap for supporting the STM32N6 series in the X-Cube-MCSDK?

Hi,I'm using a custom STSPINF0 based board and successfully profiled my motor. Using motor pilot, I have obtained a start-up profile which I've also implemented in Motor Control Workbench (6.3.1) as shown below: I've interfaced STSPINF0 with nRF52832 over USART and I'm able to execute commands & receive data successfully.But, motor runs and stalls with Fault_over/ Duration type fault when I execute MC_StartMotor1(). I think using this command my start-up parameters are not executed.I want to know does Motor Workbench stored my start-up parameters in the firmware/ STM Cube IDE? If so, how I can start my motor using that stored start-up parameters?Otherwise, please guide me how can I manually implement & execute my above start-up parameters in forms of following commands before executing MC_StartMotor1() over USART:* - MC_ProgramSpeedRampMotor1()* - MC_ProgramTorqueRampMotor1()* - MC_SetCurrentReferenceMotor1() Thanks

Hi, I'm using the boatd ihmi08. I would like to control the motor in closed loop as a target rotor angle. Is it possible in 6 steps or is the focus much better?

I used MC_SDK_6.3.2 to generate a motor control program, but found that sometimes the motherboard crashes. Debugging found that the following code has problems. May I ask why this is? Is it a hardware bug?//The problematic code is here, and the program will enter a dead loop: while (LL_ADC_IsActiveFlag_EOCS(RCM_handle_array[handle]->regADC) == 0u) { /* Nothing to do */ }The complete code is as follows：uint16_t RCM_ExecRegularConv (RegConv_t *regConv) { uint16_t retVal; uint8_t handle = regConv->convHandle; LL_ADC_REG_SetSequencerRanks(RCM_handle_array[handle]->regADC, LL_ADC_REG_RANK_1, __LL_ADC_DECIMAL_NB_TO_CHANNEL(RCM_handle_array[handle]->channel)); (void)LL_ADC_REG_ReadConversionData12L(RCM_handle_array[handle]->regADC); /* Bit banding access equivalent to LL_ADC_REG_StartConversionSWStart */ BB_REG_BIT_SET(&RCM_handle_array[handle]->regADC->CR2, ADC_CR2_SWSTART_Pos); /* Wait until end of regular conversion */ while (LL_ADC_IsActiveFlag_EOCS(

Hello,I am having an issue writing the Hardware Config in the HSO Motor Pilot. I was able to do this with my previous set up, but recently upgraded from Windows 10 to Windows 11. Along with the OS upgrade, I also installed the latest releases for all the ST software so MC Workbench went from V6.3.2 to 6.4.1. I am wondering if this is a Win 11 issue or a MC Workbench issue, or possibly a debugger setting issue?Components Used:MC Workbench V6.4.1STM32CubeMX V6.15.0STM32CubeIDE V1.19.0B-G473E-ZEST1S Control BoardSTEVAL-LVLP01 Power BoardProcess:Generate project in MCWB (Sensorless HSO option) - if errors finish generating in CubeMX - Open in CubeIDE - Build / Flash with default debugger settings via USB to onboard USB STLINK - Connect to MotorPilot (Connects fine, can tune, edit values) - Select Hardware Config (either Read / Fill from UI / Import, all with same result) - Click "Write" then the board doesn't reconnect.The errors I get in the connection bar either say "Port Open and try to

Hi there,I am trying to configure an MCSDK6 project by reference to EVSPIN32G4.On the page of current sensing, I see some config as below:  To my understanding, the three shunt current sensing circuits should utilize three operational amplifiers.Why are there just two?Thanks for the help!Best wishes to you guys. 

I bought a motor as a first step i want to run the motor profiler, the specifications of the motor are48V, Output: 500W, Rated Current: 16A, Rated speed: 600 RPM it is a geared motor with ratio of 1:6 and the number of pole pairs is 4.I got confirmation before purchase that the back emf will be sinusoidal, but when i have done hand rotation and verified the waveform between the phases i get the below waveformSo, request to please confirm if the motor profiler can be run with the above back emf? If not i have to exchange the motor. This motor is only for validating the profiler and hall sensor placement angle and understand how to change the profiler parameters before i move to the actual motor.One other question is in the window for current in profiler, i am entering 16A * sqrt(2) = 31 amps is it correct? i have run the profiler it runs for few cycles and ends up with speed feedback fault the phase currents during the time the motor is running are sinusoidal

Hi, I am using encoder mode TI1 and TI2 on TIM1 and TM3 to read encoder, however the polarity is just rising edge or falling edge. How do I know this encoder in x1, x2 or x4 mode?Thank you!

Hi,I designed a PCB with 4 STSPINs where individual STSPIN is based on the EVSPIN32G4 board schematics, i am generating code using the ST motorcontrol workbench.I am able to run and control all 4 motors except for that fact that the STSPIN's get very hot(around 65-70 degrees) as soon as i turn on the power, this is regardless a motor being connected, and i noticed the same behaviour even after doing a full chip erase.i am powering the board using a 24V supply, and 8V and 3.3V is being  generated buy the internal buck and LDO respectively, i am not using the supply generated by the STSPIN anywhere other than the sensing and feedback circuitry required. i am attaching below the photos i took using a thermal camera of my custom PCB.
