STM32 MCUs Motor control

I am using MCSDK 6.4.0 and am creating a new inverter board using STMC Board Designer.  I am using the STM32G474RETx MCU.When I select the Clock Source as "24 MHz External Crystal", save the project, and exit back to the list of boards, the "Clock Source" column correctly shows this board is using "24_cristal".  When I edit the board, the clock source reverts back to "Internal RC Oscillator". In the figure below, I have selected 24 MHz External Crystal. I press "Save" and am taken back to the list of boards.  The list correctly shows the clock source as "24_cristal"Now if I edit this board again, the clock source has reverted back to Internal RC OscillatorCould this be a possible bug, or is MCSDK forcing the STM32G747 to only operate in Internal RC Oscillator mode? 

Hi,In the motor program generated by MCSDK, I have doubts about the configuration of interrupt priority for USART and TIM. In the program, the interrupt priority for USART is (3.1), while Tim's brake interrupt is (4.1).In practical driving, the brake interruption of TIM involves overcurrent protection of the motor, which directly affects the safety of the motor and controller. However, its priority is lower than that of USART. In this configuration, will it increase the safety risk of the motor and controller when USART is frequently disconnected or in other unexpected situations? Can you help me unravel this doubt? thank you.Duan Additional program screenshot:

I try to do the motor drive using a B-G431B-ESC1 board.When I connect the board, the following warning appeared.[WARNING] - MotorControlRegistersBank: Accessing register [7449] RESISTOR_OFFSET resulted in error[5] . Changing register's access accordingly to avoid getting this error againThe software version is  V6.4.0.I could obtain the electrical and mechanical models by clicking "start profile" after the motor connected to the motor driver rotated.But, in the "register" tab, the status of register [7449] is "error".Could you please tell me how to solve this error?Thanks.

This board has slots on either side of the phase connections to the motor. Does anybody know where i can get an edge connector that fits the board?  

Hello,I was checking the current rating of the STEVAL-PTOOL4A. Referring to the its datasheet, it states that the maximum output RMS current is 20Amps. Howver using MC Workbench v6.3.2, it  states the maximum peak current is 34A.Which data is correct?Thank you. 

Hello, I am currently creating an inverter using STMC Board Designer, the MCU is STM32F407IGT6,the clock source is internal clock, here are some screenshots of my configuration, it was working fine until the inverter was generated successfully, and when I have everything ready to create the program, I get an error as shown in the picture below.I have version 6.4.0.I'm desperate to know why I'm getting this error, thanks.Best regards.{ "type": "inverter", "contentVersion": "1.0", "descVersion": 5, "name": "F407_72V300A_New", "PN": "F407_72V300A_New", "algorithmCompatibility": [ "FOC" ], "mcu": "STM32F407IGTx", "clockFrequency": 168, "motorDrives": [ { "name": "M1", "minRatedVoltage": 10, "maxRatedVoltage": 100, "maxRatedCurrent": 300, "features": [ { "type": "CurrentSensing", "name": "CurrentSensing", "tRise": 1, "hwVariants": [ { "signals": { "CURRENT_ICS_U": [ { "name": "PC2", "help": {}, "cost": 0 } ], "CURRENT_ICS_V": [ { "name": "PC3", "help": {},

[VERSION]: MCWB v6.3.2[TOOL]: STM32CubeMX v6.13.0, STM32CubeIDE v1.11.5[BOARD]: STEVAL-PTOOL1V1[PROJECT]: STEVAL-PTOOL1V1_6S_SLWhen the external power on/off input is used to start and stop the motor, if a fault is encountered when running, the motor stops and the board must be powered cycled or hard-reset to clear the faults and resume normal operation.I would like to make it so that when the external on/off input is set to off, that the firmware performs a software reset or clears/reinitializes the status so the next time the external input is set to on, that it tries to start running the motor again.What would be the best way to do this?Thanks,Angelo

Hello ,  I have a steval-ctm010v1 , a  STLINK V3 MINIE.  I want to use Motor Pilot Tool .  But J3 on steval-ctm010v1 is DP9 interface (232), and STDC14 on STLINK V3.How can I do the connection between these ports ?

Hi, I have generated code for HSO on a workbench as recommended by the release note. I need to view definitions of following functions: But not able to view the definitions of these functions. Could you please help me to open these functions? As I need to port this code into STM32F4 Series code. Thanks, and Regards,Rahul D

Hi,Could you please provide any document how motor drive parameters such as CORD_GAIN1, CORD_GAIN2 and other PI parameters are computed by workbench 6.4.0 ThanksRahul D

I'm looking into a multi channel motor controller design centered around the STSPIN32 series MCUs.To reduce part count and layout space, I'd like to power multiple STSPIN32G0 MCUs off a single instance of the integrated 3.3V buck converter. Are there any suggestions beyond not connecting the unused SW outputs? Thanks

Hi ST team,I'm using the STM32F446 MCU with the STEVAL-IPM15B power board to run a BLDC motor (310 V, 130 W, 8 poles) using Motor Control SDK v6.3.0. I'm trying to determine the exact motor parameters using the Motor Profiler tool through Motor Pilot.The Motor Pilot successfully detects the board and connects, but when I start the profiling process, it stops at 7%. At that point, the motor stalls and begins to overheat, and no profiling results are returned. However, if I do not enable the Motor Profiler checkbox and use a configuration with approximate motor parameters, the motor runs — but I’m unable to operate it reliably at lower speeds (below 1000 RPM), likely due to parameter inaccuracies.I’ve attached a screenshot showing Motor Pilot stuck at 7%. My hardware connections and power supply are verified and stable, and the MCU is confirmed to be compatible with the Motor Profiler.Has anyone encountered this issue before? Any suggestions on how to get past the 7% stall during profili

Dear, we start to handle stepper motor shield Xnucleo-IHM02A1 - with bipolar stepper motors 3A/24VDC. Is there a manual or video - how to start with...?

Hello,I have the following BLDC motor equipped with hall sensor, having an accuracy of 60 electrical degrees (15 mechanical degrees). Motor characteristics:Voltage: 18VDCRated speed 15,000 rpmRated torque  0.200 NmRated current 15.5 A Winding resistance (phase–phase) mΩ 50 Winding inductance (phase–phase) µH 42Number of poles poles 8The BLDC is connected to a gearbox of a ratio 40. I am using the STEVAL-PTOOL4A that was configured using MC Workbench V6.3.2. The motor control used is the FOC with the hall sensor as speed feedback. I have tuned the PI current and speed for high speed (max speed is 18000RPM) and under load the motor works good. However, I am struggling to have stable speeds at low values (starting 1000RPM to around 4000RPM). The motor runs with some oscillations with no load but when I put a load, it stalls and the speed falls to zero. I tried to tune the PI of the speed again, but I couldnt do better than removing the oscillations with no load.&n

Hi, Dual FOC not introduced on STM32F7 series is it due to being not implemented or peripheral of the STM32F7 series(limitations) does not supported?   Thanks, Rahul D

I have multiple issues to report with the MC Workbench (MCWB). I am using Version 6.3.2 and trying to get a dual motor BLDC setup working on custom hardware.In the .zip-file there is a minimal project required for viewing the issues and additionally what is required to run on the custom hardware.It is not possible to restrict current sensing (3-shunt setup) to one ADC, as intended by the MCWB.When trying to restrict either Motor1/2 to a single ADC with the end goal of having one ADC used for each motor, i get the following error when trying to generate the project:"ERROR [LineInfo_to_exitCode.manage_IocGenerationError] Unable to generate ioc file due to: When calling function "add_extra_regular_cnv_if_needed", required parameter "cnv" (parameter #2) was specified, but had null/missing value...."This is a bug in my opinion, because with the pinout, it should be possible to use either ADC1/2/3 for Motor2 and ADC1/2 for Motor1. The amount of conversions should also be smaller than the max

I want to evaluate a particular GaN FET found on an EPC9167 inverter board.  It has a connector on it that allows it to interface to an ST NUCLEO G432RB board.  The firmware "out of the box" is set up to run a particular motor.  I need to adjust the sensoless parameters to run a different motor.  I don't see any example projects in the Motor Control Workbench 6.4.0 that pair the NUCLEO G432RB board with the EPC9167 inverter board.  Anyone ever done this before?

[PN]: Custom Board[VERSION]: 6.4.0 [TOOL]: MC WB[DETAILS]: I am using a custom board with a single shunt current sensing topology. However, in the Motor Control Workbench (MC WB), I cannot enable the "Current Reading" configuration option. I have seen that in ST evaluation boards, such as those with single shunt implementations, this option can be enabled without issue. I expect the same functionality to be available on custom boards as well.[EXPECTED BEHAVIOR]: "Current Reading" settings should be configurable when a single shunt topology is used, as is the case with ST’s own boards. I expect to be able to enable this section in the tool for my configuration.[HOW TO REPRODUCE]: Create a new project in MC Workbench v6.4.0. Select "Custom Board" and configure it with a single shunt current sensing topology. Try to access and enable the "Current Reading" configuration tab. Observe that this option is grayed out or inaccessible, even though it should be available for single shunt setups.&

Hello,I am trying to control the speed of a PMSM with hall sensors. We are getting many random speed feedback errors that causes the drive to stop.When I looked at the code (hall_speed_pos_fdbk.c), I was surprised to find that the parameter bMaximumSpeedErrorsNumber is pretty much useless. Whenever the fault will occur, the count is set to the maximum value and the drive trips. This makes the code extremely fragile in noisy environments. Is there any way to fix this?else{bReliability = false;pHandle->_Super.bSpeedErrorNumber = pHandle->_Super.bMaximumSpeedErrorsNumber;/* If speed is not reliable the El and Mec speed is set to 0 */pHandle->_Super.hElSpeedDpp = 0;*hMecSpeedUnit = 0;}Thanks

Hi ,We are working on NUCLEO- F401RE board for motor control and to configure & generate code MC WorkBench(version 6.3.2) is used. We have driven single motor, but we are not able to configure for dual motor below pop up appeared:Hardware Setup:Motors:Power Board:Control Board:Connections:Is there incorrect configuration, or could you please suggest any other combination for dual motor (preferred control board f4 or f7)?Thanks,Harsh   

Is there any mothod solve this issue  If the Friction parameter is not provided by the motor manufacturer ?

Hello ST Community,I'm currently working with the STEVAL-CTM012V1 evaluation board and have encountered an issue using it with the latest Motor Control SDK (MCSDK) v6.3.0.This board does not appear in the supported hardware list of MCSDK v6.3.0, so I downloaded the firmware package for it from the official ST product page. The package is based on MCSDK v5.4.4, and the PDF with that instructs me to load the configuration file named “STEVAL-M01xV11shunt_FOC.stmcx” using the Motor Control Workbench. The .stmcx file is not detected or listed when I try to import it in MC Workbench v6.3.0 and the provided inverter JSON file (STEVAL-CTM01xV1.json) shows as invalid when I try to import it via the Board Manager, Screenshot attached. As a result, I’m unable to open or upgrade the project for use in the latest SDK.Could you please advise:Is there an updated configuration package (JSON and STMCX) for MCSDK v6.3.0?If not, what is the correct procedure to migrate a v5.4.4 project to MCSDK v6.3.0?Wi

I have a problem with setting up and flashing the P-NUCLEO-IHM002 using the Motor Profiler and STM Motor Workbench. Kindly help me in setting this up, preferrably run a example folder either six step or foc. Once done, help me integrate with Matlab simulink MBD workflow. Also provide methods for manual code addition in the generated code using STM32CUBEIDE.

I am trying to run a custom board using MCSDK micro STM32G4 series,  using cube monitor took the waveforms i have queries on the waveforms pls help me if they are correct or abnormala. Phase currents are not correct, i am not sure why are not overlapping, i mean 120 phase shifted.b. CntPhA, CntPhB, CntPhC look to be ok for me but the problem i am observing is the duty cycle is going upto 5000 i have set the system at 15Khz hence the max count is 5666, does it mean it already got saturated, i am running the motor at 26V the motor is run at 60V in the vehicle.Vq graph c. Vq also going upto 25000.d. /*** Noise parameters ***/#define TNOISE_NS 500#define TRISE_NS 200i have never measured the above values on the scope including the Dead Time for my system, is it mandatory to measure the above values and input to the system.
