MCSDK 6.4.0 is out!

Dear MCSDK users, MCSDK version 6.4.0 is now available: Download It here. This version of the new Motor Control SDK 6 series (X-CUBE-MCDSK) provides mainly FOC and 6Step improvements, here are the main changes for this version: Motor Control Features...

Board Manager documentation is out !

The documentation of the Board descriptions format is now available on Motor Control Boards Description Wiki page, this documentation is compatible with MCSDK versions from 6.1.2. Board Descriptions are used by the ST motor-control workbench to enabl...

How to write a Motor control post to get a response quickly

In order to have a quick response to your forum posts, the best way to ask the question is:- Give the version of the MCSDK used. - Say if the problem concerns a tool (MC Workbench, Motor Pilot, Motor Profiler, etc...) - Provide picture of tools inter...

Resolved! Newly created Inverter disappears from MCWB 6.1.2 new project wizard.

I am trying to create a new inverter board for a Motor Control Workbench 6.1.2 project. I have tried several methods :1. Create clone of B-G431B-ESC1 in STMC Board Manager at choose Inverter stage of project wizard.2. Create new board in BM and save ...

PWM complementary Output

Hi,I try to implemend sinus algorithm for BLDC engine on STM32G474RE chip. I want to use TIM1 (CH1 - CH3) and (CH1N - CH3N) to control a bldc controller. I have configured a complementary output with dead time according to datasheat (so I think) an...

Resolved! Hall Sensor - ST MC WB

I successfully ran the BLDC hub motor with sensorless method (sensorless + PLL) with EVSPIN32G4 hardware. My motor have the inbuilt hall sensor with 60 degree placement. Now, I am trying to configure with hall sensor. I get the speed feedback error i...

Resolved! Hi. Does anyone have the official documentation for the MCSDK 6.1.1 ASPEP/UART protocol? I sadly could not find any official documents for it. I'm using a STEVAL-SPIN3204 Evaluation board. Regards Xun

6step code generated from MC Workbench never detects failure to transition to sensorless

In other words, after the ramp up, it always thinks it locked and is spinning even when it doesn't. I've written this code before so here is where I'm suspicious if anybody here is familiar with this code:There is a parameter in drive_parameters.h ca...

Resolved! Speed Mode in MCSDK (custom board, software of B-G431B-ESC1) is not working

Hi all,I am using the software generated from MCSDK motor control and a custom board, I am able to successfully make it work for the torque control mode, for different Iq values the DC power supply current is varying.But i am facing problem with spee...

Resolved! X-NUCLEO-IHM01A1 and development board

Hi STM,I am having NUCLEO-476RG and I am planning project with steppers (by using X-NUCLEO-IHM01A1). Can I connect this expansion with my development board. And also, what is the maximum number of expansion boards I can connect to the development boa...

Resolved! OV_VOLTAGE_THRESHOLD_V parameter in the MCSDK 6.1 generated code.

Hi,I am having issue to find a work around this parameter.I do not specifically set any over voltage threshold but it seems to be present there already, so i am guessing that's something hard wired by ST. Is there a way, other than changing manually ...

Resolved! MCWorkbench Generated Project does not start properly (B-G431B-ESC-1)

Hi, I am having a trouble using MCWorkbench 6.1.1When downloading a project generated from MCWorkbench demo to my B-G431B-ESC1, this happens(the rotor moves for some angle per each second while making a wierd noise. It temporarily stops when I push t...

Resolved! Motor does not start with B-G431B-ESC1 board.

Hi all,I'm new to the STM32 world and ST motor control tools, so I might be missing something obvious.I have the B-G431B-ESC1 development board connected to a BLDC motor.I generated the code for FOC with the MC-WB 6.1.2 and STCubeMX 6.8.1. Compiled w...
