STM32 MCUs Motor control

I'm having following issue with the Motor Pilot that comes with the MCSDK 6.2.1 (V1.2.5).I try to modify the Rev-up phase configuration.Now when I write a torque value in any of the phases, this value resets to zero and is saved on the board (pressing "Read parameters" returns the zero values). If that happens, I cannot set it to any other value until I power-cycle the board, in which case it resets to the values predefined in firmware.Any way to make this feature usable again?

Good day all, I was found project on github, and interest to learn about it, but that projec was made by MC SDK 5.y.0 but i see no more aviable that version only 5.4 and 6. When i open it by version 6 they say ioc is infalid. So what sould i do?? Any one know how to migrate code mcsdk 5.y.0 to version 6??? Also error when i open with with cubeMX version 6.Thank u all:folded_hands:

Hi,I am new to this community. I want suggestion regarding, going to do the setup of two-axis gimbal with Nucleo stm32f429zi and two gdm4108 motors. Is this setup will work?What are all things to cover?Regards,Kamalesh

Hi,I have been looking for a reference design using ST's product for driving a sensorless BLDC Motor. The BLDC Motor requires 3-ph 12-18V to 30A and I am able to drive it using L476RG+IHM08M1 boards. There is a schematic available for IHM08M1 but I want to know if there is any ST's reference design/ guide available for my application requirement? I will be developing this board for my personal use not commercial purposes. Is it fine that I can reproduce the schematics and copy the layout from IHM08M1 board?Any guidance/ suggestion will be appreciated.Regards

Hi All, I met some issues in ST Motor profile. It showed me waning as below when i click connect.I am sure that serial port was not used by others.I flashed a uart sw and it can work normally.My control board is Nucleo G431RB, power board is X-NUCLEO IHM08M1.ST LINK Driver info is attached. I updated the ST LINK, but this issue is not sloved.Could you pls share me your advice about it ?Thanks,Qin

Hello everyone,I would like to understand about MC library and some motor control terms. 1 - I want to use my own power board and motor. In this case, how can I specify the PID and motor parameters using MC workbench.2 - is auto tuning available in this library. I want to give this product to costumer to use it in application. Probably I dont have enough information about autotuning. Should autotuning be performed under load or while the motor is idle? For example motor mounted in CNC machinethen how autotuning must be performed, mounted or unmounted?Can you explain me the stages to manage this. Thanks in advance.

We're trying to get a 3 phase, 18 pole pair, <150V <5A motor going. When we try to start with evspin32f0601s1, it slowly stutters forward with a regular forward-back motion at about 10 RPM. Looks like it might be going 2 poles forward, then one pole back? I'm using bemf, resistance and inductance values provided by the manufacturer.  evspin32f0601s1 - We were planning to use this one, but can't get it to spin up at all beyond that 10 RPM halting movement evspin32f0251s1 - spins up, but needs tuning (gets jittery and power draw spikes at a few hundred RPM, and RPM caps out pretty low) Tested 2 motors and 2 f0601 control boards with same results, and it works on the f025 board, so pretty sure we've ruled out hardware issues with control board, motor, or wiring. I tried messing with a bunch of parameters just in case in MC Workbench, mostly with little to no effect. The only thing I can think of that's different between the two boards is the bemf resistor di

Tools : MotorControl Workbench_6.3.0, CubeMX_6.12.0, CubeIDE_1.15.0Issue : The start/stop button is configred in .stwb6 as attached but this button does not shown in "User Interface"  and "Pin Usage & HW Changes"tab. I tried to generate the project this button is not created.Please help to solve this issue.Thanks and regards, 

I need a way to manually calculate the parameters for the speed, torque and flux regulators.The reason is that the MCWB tool is too inaccurate and cannot handle the parameters of our motor.The tool messes with following motor values:- Rs of 5.825mΩ gets converted to 0.01Ω- Ls of 3.715µH gets converted to 0.004mH Alternatively, can you provide me with correct regulator parameters for these motor values?

Hello,I am currently working with the STM Motor Control SDK (version 5.4.8) and noticed that it only supports STM32G474, while my project requires using the STM32G473 microcontroller.Is there an option to add STM32G473 as a new package to the SDK? If yes, could you guide me through the process or provide relevant resources?Any insights, suggestions, or references would be greatly appreciated.

Hi,While reading the "HSO Startup Guide" included in the release notes of Motor Workbench 6.3.2, I came across a recommendation regarding the filtering of voltage: This raised the following question: considering that the only development kit offered by ST to test the HSO algorithm consists of the B-G473E-ZEST1S + STEVAL-LVLP01 + B-MOTOR-PMSMA1, where the B-MOTOR-PMSMA1 is based on the R57BLB50L2 motor with 2 pole pairs and supports a maximum speed of 5000 RPM (i.e., 167 Hz of electrical frequency), the suggested phase voltage filter cutoff frequency of 500 Hz seems appropriate.However, if I were to test the algorithm using the B-G473E-ZEST1S in combination with a custom-designed power board to control a PMSM with 2 pole pairs capable of reaching 90 kRPM (i.e., 3 kHz of electrical frequency), should I maintain the 500 Hz filtering for the phase voltages, or would it need to be adjusted accordingly?In other words, does the HSO algorithm use phase voltages to calculate the angle inde

Hello I'm evaluating B-G431B-ES1 design.As I don't have accurate specifications for the motor, I'm going through motor profiler. If I use SDK 5.4.8, profiling seems to work. At least, the motor turns.If I use SDK 6.3.2, profiling whistles while keeping the "startup beep-beep" but the motor never starts. Before that, I built a firmware with the motor profile option activated. What did I miss?ThanksJulien

Hello ST Community I am experiencing issues while trying to operate the GBM2804H-100T Motor  with  the nucleo G071RB board and IHM16M1 motor driver board.The G431RB board and IHM16M1 motor driver board are succeeded in operating the motor. But in the case of  the nucleo G071RB board and IHM16M1 motor driver board are some error occured for example,can't connect to motor pilot GUI and also FOC duration error in the GUI.■Our Developement emvironment・Software：Generated by MCSDK6.3.0/STM32 Cube MX・Compiler：STM32CubeIDE 1.13.2・ST Motor Pilot V1.2.9 what will be the issue , can anyone help me with this.  

I'm trying to use a RS422 transceiver set up between ST Motor Pilot and EVSPIN32G4 development board.I'm using an FTDI USB-Serial converter and two RS422 Transceivers with /RE and DE signals.Is it possible using the ST Motor Pilot to use these hardware flow control signals to set the transceivers in RX/TX modes as transmission occurs?

Hello,I want to control the evaluation board using the serial protocol?Where is the documentation for this protocol?Is there any C/C++ file ready to integrate to create the frame?Thanks

Hi,First time for me with this kind of board and ST IDEs, I need help to start the project.The drivers are ok, I can connect the board with STM32CubeProgrammer (ST-Link).I made a project with MC Workbench, the code is generated with no errors.But : I don't know how to program the device. I only have .c files, and In the "Erasing & Programming" (STM32CubeProgrammer) I need to put an hex or bin file.I miss a step, I don't know witch one.Can someone tell me how to continue ?I guess that after programming the STM, I'll be able to communicate and use the motor pilot and profiler.Regards.

When I parse the data sent according to the motor protocol, I find that it is completely different from what is written on the protocol. I am using st's P-IHM03 motor communication board, but when I want to communicate with STM32G431, I can't compare his data with the protocol. The data I sent is on page 22 of the document, and the other picture is what I sent, but it doesn't seem to correspond, so I asked the big guys to help me parse the data bytes. TX: 85 FF FF BF RX: 05 C7 01 14 But I don't know what each bit means!!!   *This post has been translated from Chinese to comply with the ST Community guidelines.  

I am having false Over Current conditions when the inverter board starts up, before any kind of operation.Motor Pilot shows Over Current fault that happened but FAULT_OVER, most likely a short condition that prevents further operation without acknowledge. Once fault is cleared everything seems to be working normal.In MC Workbench I have increased Digital Filter Duration to 1.51ms in both Drive Protection and Over Current Protection tabs.Testing is done without any motor connected to the board.Anyone having similar problems? Is this reproducible on other boards? 

Trying to update a test project from MC Workbench, I get the error "Fail to copy Extra folders" and generation fails.Log shows:2024-11-19 12:40:56,300 ERROR [Wb2MxProcess.copyExtraFolders] Fail to copy Extra foldersThese are the steps to reproduce:- Create new project in MC Workbench.

Hello,While I did tests with my motor control STEVAL-IHM028V2, I made a mistake to schort-circuit the three-phase output ! Then, I smelled a burning smell and no voltage is given in the three-phase output . When I checked the bottom face of the device, I noticed that some resistors (R74, R75 and R69) are burned (see attached images). Also, the W7 and W8 jumpers are short-cicuited. How could I fix this issue ?N.B. The schematic of the STEVAL-IHM028V2 is attached.CordiallyTarek 

I am newbie of mc workbench.I'm in trouble with making custom board configuration of MC workbench. I think there are some restrictions for usage of MC workbench.When configuring 2 bldc motor settings, I want to receive individual PWM inputs, but I can't write that configuration. My final goal is to control 4 motors via 2 STM32G431.So, 1 STM32G431 should have 2 pwm inputs. but I can't configure this setting. is it right? And, please quickly upgrade to drive 2 motors in 6 Step control.

Hello I need help for STSPIN32G4 EMI IssueI took tests for Farfield EMI Report at STSPIN32G4 Standby conditionReport shows QP are over than Limit at 189 MHz, 252MHz.  It doesnt depend on the input voltage and the signal  peeks are visible also if the microcontroler is running in the loop only.Similar problem has also another user Dkim-39 and here is his measurement.  Do you have any solution for this problem?Thanks   Josef Pazderka   

Is there any support for evspin958 connected to the Nucleo-G071 board? I’m not really sure how to proceed. I need to control a DC motor back and forth using PWM. I can’t find any libraries. X-CUBE-MCSDK doesn’t seem to support this combination. STSPIN Studio is for another dev board (and doesn't even start). How should I move forward? Any examples?  Grateful for any tips!
