STM32 MCUs Motor control

I am currently facing an issue with the RPM readings while running a motor using the STEVAL-IPM10B and NUCLEO-F302R8 in conjunction with the ST Motor Control Workbench.Upon measurement with a tachometer, I observed a difference between the practical RPM values and the readings displayed on the dashboard. Even though I utilized the Motor Profiler to generate motor parameters.I had attached the Program files for your reference.Thanks in Advance. 

I am currently encountering an issue while configuring the Motor Control Workbench. Upon completion of the configuration, I receive an error stating "ST Intranet Updater Server is unknown: mcucrossselector.codex.cro.st.com." Additionally, the compilation process in Motor Control Workbench results in "Compiled with errors."I am using STM32 Cube IDE to upload the program. Could you please provide guidance on whether this server error is something that needs attention, or if it can be neglected?Thanks in Advance

I am working working with a PMSM FOC project in MC Workbench 6.2.1 and I am wondering if there is a way to change the mcu's analog vref input voltage. From the numbers I'm seeing on the current measurement page, it seems like MC Workbench is expecting the mcu to have a 3.3v reference on the vref input pin of the mcu. However, I don't see a way to change that in MC Workbench or a field for it in any of the board files for the control or power boards. The custom board I am using has a 3.0v input to the vref+ pin on the mcu. Is it possible to input this information anywhere?

I need help with the code generated by the workbench.I am using the STEVAL-CTM01xV1 shunt code with the STEVAL-CTMo11V1A development board and the STLINK/V3 with the isolator adapter.Following the instructions that appear in the comments of mc_api.c, I added the three routines before the main while:MC_ProgramSpeedRampMotor1(1000,250);MC_ProgramTorqueRampMotor1(935,200);MC_SetCurrentReferenceMotor1();In the last routine, it is not clear what the parameters, units, etc. are like.Documentation is missing or at least I can't find it, I need more information to be able to continue with the development.

Hi Team,We are using this P-NUCLEO-IHM03 board for our motor control application.Is the Self-commissioning feature available on the MC 6.2.1 workbench?If yes, then could you please help us enable the functionality? and help us understand this feature in a better way.Thanks Akhilesh 

HiI m currently implementing a project using  MC Workbench software. There is a DAC Functionality subblock in the COntrol Unit block.  Can you tell me what is this block and why it uses two mcu pins as DAC ? For users which designing a custom board,  what should they do with these pins ?Thank you 

Hello, I'm using Blue Pill Board With TMC2209 Stepper Driver To Control 3 Stepper motors. I've made a project using Arduino Mega and there were MobaTools & TMCStepper libraries available to Set Current and run multiple motors at once smoothly.  I wanted to know that, how can i do the same with Blue Pill Using STM32 Cube IDE ? Is there any special library to do the same stuff ?  Any help is appreciated. Please let me know if anyone have any answers.  

Hi all. Is posible to change MCU and coustem Driver for MC Workbenc stm32?? I found the code with B-G431-ESC development kit/board and used step/dir interface for control the motor. But in my country very hard and expensive for that board( iwant supplay around 50-80V) so i want coustem the driver, used ir2101 or semilar with HIN and LIN input. And for the code already done( i see all code complate with mxcube  and ide also) so it posible to change with stm32f401?? This board easy and cheaper on my country. Because i want to control the pmsm motor with step/dir interface. That used mc workbench version 5Y. Not version 6.Or i must build from zero the code and put step/dir interface, copy from firt code i mention?? Because i confiusd how to add step/dir/enable interface for control pmsm motor. I want to used for my cnc, it pmsm motor with quadature encoder 2000ppr.Thank u so much. I hope somebody can help me:folded_hands:. 

[VERSION]: MCSDK 6.2.1[TOOL]: 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 am using a dynamometer (link below) to measure maximum torque:<https://www.magtrol.com/product/hysteresis-dynamometers-hd-series/>I am facing a problem when starting the motor with speed mode when reaching 1.1Nm (the motor is rated at 1.5Nm). When I add load while the motor rotates, the controller can adjust the current accordingly, look at "add_load_after_start.png".I already adjust speed PID so that it could increase the Iq reference (mainly through the integral portion), but it seems it is not fast enough as the system detects a motor stall (custom implementation - system requirements - minimum speed at 5% nominal in 6 seconds). Starting with torque mode (setting a short-time ramp to the motor's nominal current) and then changing to speed mode seems wrong, as Iq and Id go to zero after the

Hi Folks,I've purchased a STEVAL-EDUKIT01 project.I've assembled it and am failing in the last step, which is installing the software.  I need a file named 'pendulum01.bin'.  I have had no luck in locating this file.Anyone have an idea to locating this file?Thanks,John Mazur.

Hi,I'm working on a project for an SM-PMSM motor drive. The end customer would only like communication via USB (with a micro connector).Is there a possibility to implement MCP and ASPEP protocols on the USB port instead of a UART?Has someone already done it?Is it planned for the future?

Hello guys, I want to control an AC servo motor (ELM2H-0400LA60F) and a Motor Driver (RS-400P) with an STM32f407 discovery kit. But I cannot find my motor and control in the MC Workbench. Is it possible to work with MC Workbench in this regard?? 

I am working on the STM32F407 and we made some bad choises when selecting a motor. The motor control signal is 5V hence we need to generate 5V PWM signal using the STM32F407. Sadly, we have wired the GPIO from the STM32F407 directly to the motor control pin. I am aware about the 3.3V - 5V logic level converters but I was wondering whether it is possible to achieve what I want using just the STM32F407. I know that some pins are 5V tolerant. For example, PD15 pin on the STM32F047 is 5V tolerant as it is marked with FT: 1. I have configured this GPIO as Output Open Drain: 2. I have soldered 30k OHM resistor from the GPIO8 to 5V And simply tried to set the ping to high using the following command: HAL_GPIO_WritePin(GPIO8_GPIO_Port, GPIO8_Pin, 1); HAL_Delay(1000); HAL_GPIO_WritePin(GPIO8_GPIO_Port, GPIO8_Pin, 0); I can confirm that the GPIO is toggling between 0 and 5V:Next, I try to configure PWM for this pin: 1. Enable pin stacking for this pin since I

Hi,I am trying to get the STEVAL-CTM011V1A working with the STEAVA-CTM01xV1 1shunt_FOC firmware that I downloaded to begin evaluation and development.Buy the STLINKV3 development board and attached programmer with the isolator accessory.The only thing I get is the error "The ST intranet updater server is unknown: mcucrossselector.codex.cro.st.com" and when running the ST engine control workbench version:MCSDK_v5.4.8-FullWB_to_Mx version "1.5.1"WB_to_Mx.template version "21-11-15"[Device]Device not connected[Modules]MMICalc DLL - Version 1.0.4.0Basic Motor Control Serial Protocol Library - Version 3.3.0.0TL_003 Frame Transport Layer - Version 1, 0, 0, 0PL_001 Dynamic Link Library - Version 1, 1, 10, 0I attach a screenshot of the error result.I can't move forward, apparently, to be able to run an engine and begin testing the code it generates.I need help.

I am trying to launch a MC Workbench project targeting a STM32G431CBUx mcu as the controller. I tried to modify an existing control board file to use the STM32G431CBUx as the mcu. I am able to select my custom control board on the selection page, as well as accompanying power and bridge board. However when I click "OK" in the bottom right corner to try to open the project I get a popup with this message: "The hardware selected is not compliant with the selected algorithm. Please review your selections"Wondering why I am getting this error. Is the STM32G431CBUx mcu simply not supported at this time? Is there an alternative way to open an MC Workbench project with my intended target mcu?

Please refer to the attached file.I want to change the PB3 pin of Encoder B and use SWO.Please tell me how to change the pin.

According to here:https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:Frequently_Asked_Questions#Why_does_not_my_motor_start_immediately-3F The STM32 MC motor profiler has the following limitation: it cannot profile motors with Rs < 1 Ω or Ls < 1 mH.That wording is a bit different from saying "is not optimized for" I saw elsewhere earlier.I have a bunch of quite different PMSM motors - candidates for different purposes, and every single one of them is shown to have lower values (e.g. R=0.8, L=0.1m) than this in the MCSDK Profiler, on a IHM16M1 driver board. (the profiling completed, but I assume the determined values are to be regarded as unreliable?)Can someone point me to descriptions of what type of gear & procedures are needed to profile a motor with lower values than these, to get the parameters to work with MCSDK?

Hello,is there is an option of adding input pin for external PWM? I want it for ESC, I would like to control it with PWM signal like on board B-G431B-ESC1. I tried with STSPIN32F0A board example, however adding ESC to .json file doesn't do anything. I added with PA6 pin from STEVAL-ESC002V1 schematic. The attached photo is for B-G431B-ESC1 and I would like to enable it also for STSPIN32F0A.  Could you please tell how to configure the board for PWM input? Thank you!Kind regards,JS

Hi Team,I have enabled the flux weakening for the Motor. But as per my understanding, flux weakening helps us to run the motor beyond the rated RPM. But in my case, I am not able to see that difference.Could you please help me understand how it works or have I missed some of the steps while configuring the project? 

Hi,please advice with the issue of motor profiling.mcsdk: 6.2.1control board: nucleo-g474reBridge: XNUCLEO-IHM09M2Power Board: STEVAL-CTM009V1Motor: Motenergy ME1304 How can I run motor profiler for this setup?MC Workbench does not allow to generate FW for motor profiler. Best regards, Taras.

Greetings. I need help because when generating the evaluation code for the STEVAL-CTM011V1A it always gives me an error.I follow all the steps in UM2962 and I can't get the evaluation board to work. I attach a screenshot of the moment when said error is generated.

hello.currently, I am working on the P-NUCLEO IHM03 3SH kit with my motor motor specification is mentioned belowpole pair = 6V = 56.4RPM = 2100I want to use the hall sensor as speed sense but I can't understand how to find the placement electrical angle for this my sensor displacement is 120 degree

Hi.I have the IDE with the STEVAL-CTM01xV1 shunt_FOC and downloaded on the Board. As the example came, the motor doesen't work.I opened the main.c file and I could see that it does not have any function inside the main while(1) loop. How could I have a working example to start testing the board?
