STM32 MCUs Motor control

Hi,   I am interested in the um2647 product. Like to explore more in 6step firmware, how to download the firmware for this product. I saw that using work bench it can be extracted, but I need the complete code which cannot be done in the work bench.

Sorry for any silly questions asked, but please help since I am actually a beginner.Ques: I can see most of the FOC steps are inside "FOC_CurrControllerM1" function. And we just add below code in main() for motor to start and run: MC_ProgramSpeedRampMotor1(RPM_2_SPEED_UNIT(1200), 2000);MC_StartMotor1();MC_StopMotor1();But I want to know from below code where does "FOC_CurrControllerM1" called? How this code is following FOC Algorithm flow ? I am using NUCLEO-IHM07M1.   

[VERSION]: MCSDK version 6.3.1[TOOL]: MC Profiler[HARDWARE] EVSPIN32G4 Hi everyone,I have a question regarding the hall sensor placement electrical angle parameter.I have tried identifying the hall sensor placement electrical angle with 2 different methodsRunning the hall sensor profiler in the motor pilot, as outlined in the MC workbench documentation chapter Motor Profiler Application Note, section 5. Hall sensor profiling with the Motor Profiler toolMeasuring the delay between the Phase U back EMF and the first rising edge of hall sensor H1 with an oscilloscope as outlined in https://community.st.com/t5/stm32-mcus-motor-control/is-this-a-120-or-60-deg-displacement-angle-hall-motor/td-p/263494 and um1052 section 8.3.3 https://www.st.com/resource/en/user_manual/um1052-stm32f-pmsm-singledual-foc-sdk-v43-stmicroelectronics.pdf. Since my motor is wired in a delta configuration, there is no neutral point to reference the phase voltages. So as suggested i

Hi, I'm newbie to Motor Control workbench(6.3.2) . I have STM32 G431RB and IHM08M1.I want to control the position of BLDC (42BLFX01E). This motor has 3 Hall Sensors.  I successfully run the motor using motor profiler and implemented the speed control. Now for position control when i selected my IHM08M1, STM32 and relevent motor in FOC Wizard. I can only select Torque and Speed Control. Is there any way to implement position control without encoder ? Thank you

I'm trying to set up a custom board based on the B-G431-ESC1, with the MC Workbench and the SDK Version 6.2.1.My intention is to use sensorless for development and then have the option to switch to sensored (Hall, Encoder) in the future.I set up the board accordingly in the Board Manager, here is the relating section of the config:{ "name": "SpeedAndPositionSensing", "type": "SpeedAndPositionSensing", "hwVariants": [ { "type": "HallEffectSensor", "help": "SW 9 and 16 to consider", "signals": { "HALLSENSOR_H1": [ { "name": "PB6", "help": "", "cost": 0 } ], "HALLSENSOR_H2": [ { "name": "PB7", "help": "", "cost": 0 } ], "HALLSENSOR_H3": [ { "name": "PB8-BOOT0", "help": "", "cost": 0 } ] } }, { "type": "QuadratureEncoderRelative", "help": "SW 9 and 16 to consider", "signals": { "QENC_A": [ { "name": "PB6", "help": "", "cost": 0 } ], "QENC_B": [ { "name": "PB7", "help": "", "cost":

OCP in STEVAL-ESC001V1 is mentioned in its user manual, but in MC Workbench while generating project, neither OCP nor Driver Protection support is present. Please clarify?

Hey,So we're trying to modify the motor control SDK to fit our needs.We currently use the EVSPIN32G4 to evaluate the performance of the motor control SDK with our motor and our requirements.We're using an SM-PMSM motor, which works in a rated voltage of 24V, max current of 24A and 21 pole-pairs and has Hall sensors installed. We're trying to spin it using Hall sensored-FOC.The issue we're facing, is that when we release an applied load on the motor at once, the motor's speed rises significantly, followed by a big spike in the current in-take of the motor.It often leads to over-current or over/under voltage faults.Is there a way to control that big spike?  Thanks,Eyal

I want to use HFI to start the motor. Does ST provide any relevant documentation or code?

MCSDK v6.3.2 It looks like the STM32 is failing to PWM fet gates and that's resulting in high current and an Under Voltage fault.I made a board with the STM32G431RBT6 and DRV8323 driver chip. I've used the DRV chip in another board for a long time with no issues.  I based the board on dev kits, but I have all pins jumpered so I can change any wrong connections if necessary. First, even with no command to the motor is looks like the motor control firmware is PWM-ing the fet gates. This is from boot not sending any commands:And here are the signals from trying to start the motor with Motor Pilot.  This results in a fast torque, then the motor cuts off and i get the Under Voltage fault:  There does not appear to be any pwm-ing of the fet gates, just all on or all off. Does anyone have an idea what I'm doing wrong?  I've attached the project files and double checked all signal connections

MCSDK Version is 6.2.1.I'm currently having the issue that our motor doesn't reach the configured application speed of 7600RPM.It stops increasing in speed at around 6500RPM.The motor is slightly loaded for my tests. I'm running in Torque mode with the target torque set to the 150A the design can and does handle. The torque maxes out at around 30A, so phase current is not an issue here.The High Frequency Plot shows a phase voltage V_Q of 7V. The system voltage is 12V.What is the limiting factor here and what can I do to reach the application speed?

Hey, I had recently purchased an EVSPIN32G4 board, and I'm currently trying to use the MCSDK to generate code for it.When I'm trying to generate code for it, it completes with the following error:How can I solve this issue?Thanks,Eyal

Dear all,I have a NUCLEO-F302R8 and the X-NUCLEO-IHM07M1 motor driver expansion board. I have a three phase BLDC motor with an encoder attached to it. I want to implement a torque controller. I am able to use the workbench software to implement the torque controller and set the desired torque. This works fine. However, I want to be able to adjust the desired torque in the while loop of the main function. Unfortunately, I am not able to achieve this. Do you have any ideas on how to achieve it? 

Hi,I am developing on EVSPIN32G4, MC Workbench 6.1.2.The only option for Over Voltage Protection is to turn on Low Side Switches. This unfortunately doesn't work as I still constantly get Over Voltage faults in position control mode, when the motor is trying to stop on position. It generates enough back current to spike it above the threshold of 32V on a 24V PSU. I have an older custom design with a large Braking Resistor switched by a MOSFET. The output for this option was available in earlier versions but I can no longer find it anywhere.Are there any working solutions out of the box for over voltage protection?

Can use STM32H723 in X-CUBE-MCSDK Ver.6.2.3?

Hi, I'm using MCSDK 5.Y.2 and STSPIN32G4 on a custom board. (this is a software thing !)I couldn't find a way to get two (more than one) converted ADC Values using a single request using the RCM.So I carried on converting each channel sequentially.I made two Registrationslike so  void User_ADC_Init(void) { RegConv_t FES_ADC = {hadc2.Instance,MC_ADC_CHANNEL_7,ADC_SAMPLETIME_2CYCLES_5}; FEShandle = RCM_RegisterRegConv(&FES_ADC); RegConv_t TRTL_ADC = {hadc2.Instance,MC_ADC_CHANNEL_8,ADC_SAMPLETIME_2CYCLES_5}; TRTLhandle = RCM_RegisterRegConv(&TRTL_ADC); }  But started with converting just one of the channels  void User_ADC_Conv(void) { switch( RCM_GetUserConvState()) { case RCM_USERCONV_IDLE : RCM_RequestUserConv(FEShandle); break; case RCM_USERCONV_REQUESTED : break; case RCM_USERCONV_EOC : FES_Datum = RCM_GetUserConv(); break; } /* switch( RCM_GetUserConvState()) { case RCM_USERCONV_IDLE : if(adcSelect ==

Hello everyone,I have a motor control project that I'm testing out using Motor Pilot. If I generate it with FreeRTOS support, Motor Pilot can't connect to the board (the board sends a probably malformed ASPEP_RESP and then it's always a timeout).I have verified that motor control code is working correctly with test code (the motor spins as expected):void test_task(const void *arg){ vTaskDelay(5000); (void)arg; MC_AcknowledgeFaultMotor1(); MC_ProgramSpeedRampMotor1_F(250, 1000); MC_StartMotor1(); vTaskSuspend(NULL);}Noticed that void ASPEP_HWReset(ASPEP_Handle_t *pHandle) from aspep.c is always getting called.If I untick the FreeRTOS button in the workbench and regenerate the code (keeping all other settings), then MCP works as expected.General params:MCSDK 6.3.0FOCEVSPIN32G4 Maybe this is known issue and there's a fix/workaround?

Hello everyone,I am utilizing the IHM08M1 board for a Voltage Source Converter (VSC) academic project.The IHM08M1 board's Gate Driver L6398 already incorporates a set deadtime of 320 ns for the control signals of LVG and HVG.I would like to know if this dead time value is sufficient to prevent cross conduction of the MOSFETs on the IHM08M1 board (Power MOSFETs STL220N6F7) and shoot-through currents. If not, how can the "extra" dead time (to be implemented via software, i.e., microcontroller) be determined?Thank you.

MCSDK version is 6.2.1Our motor is running fine and can drive some load, however I'd like to increase the Phase Voltage with which our motor is driven to further increase its power output.When checking the High Frequency Plot for V_Q (and thus the peak voltages for V_alpha and V_beta), it always hovers at around 2V even under high load. The system's supply voltage is 12V.Which values do I have to modify to change V_Q?

Hi,I'm Using STSPIN3201 board, i wanted to run sensorless motor with 6 step commutation. can any one help me for this?

Hi experts,I'm using MC workbench to generate a project using NUCLE-G071RB to control a simple fan. No matter which power board or motor, i can't set the current regulator execution time higher than 83us. I need to use 20kHz PWM frequency so 50us current regulator execution time is preferred.But from STM32 Ecosystem for Motor Control, i find the information below. When FOC is 10kHz, the total workload of G071B is just 37%. So i plan to use STM32G071B to do this motor control with 20kHz FOC frequency.So it's confused for me and please help to clarify the reason why current regulator execution time should higher than 83us when the workload just 37%.Could you tell me how long the FOC execution time once when using PLL observer, speed & current control and SVPWM? I have some other functions need to add, so i need to know that.Thanks a lot!Best Regards!Jinchun Chen

Dear, I have custom board based on this https://github.com/issus/BLDC-Drive which uses STSPIN32F0 as motor driver. I have that got that PCB manufactured & assembled but stumbled on an issue (which I assume is an issue) that it does not have feedback resistors on current sensing op-amp circuits. I have added those manually on the PCB. I am able to program and connect to the board using MCSDK 5.4.8 monitor but whenever I press start motor start-up failure occurs. I can share all the files need if required but I want to know the procedure to diagnose this startup issue. I have a 2-channel oscilloscope with me and I can probe those inverting signals as well. MCSDK 5.4.8 & schematic are attached for your quick reference. I will be grateful of your help in this matter. RegardsShahid
