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...

User manual UM2200 for STEVAL-ESC001V1 (purchased recently) tells me to install STSW-STM32100. I have searched st.com but cannot find it. The databrief tells me I shall have a motor running in minutes. So far it's 3 days. What do I do?

How to tune FOC PI loops in motor control workbench

Hello Can you point me to some documentation regarding the tuning of the PI control loops in motor control workbench, I found this video https://www.youtube.com/watch?v=Tmq2PL8bf3g&list=WL&index=40, this outlines the procedure using the rev-up table ...

Resolved! Hello,im working in BLDC motor using stspin IC.for testing purpose im usinmg STEVAL SPIN32F0 Board,but in that motor is runing only with plug into software.without connecting the stworkbench motor is not running.how i will come from this ?

Also there is one pin that is connected to potentiometer.but there is no any options in st workbench to varry the speed using potentiometer. I look forward to hearing from you as soon as possible.thank you

I can't distinguish comp4 and comp 6 in interrupt

hello everyone,ı am trying BLDC motor driver with stm32f302R8 but ı having a problem with comp4 and comp6 interrupt. when ı input COMP4_6_IRQHandler, ı try to distinguish comp4 and comp6 interrupt. but both comp4 with comp6 be activating. ı can't fin...

Resolved! ERROR: ASPEP PACKET ERROR Bad CRC Header

Hi, I am using board B-G431B-ESC1 and Motor Control 5.Y.3.When controlling the motor through the Motor Pilot and increasing the current, I get a recurring Bad CRC Header error.There is a neighboring forum thread where this is discussedhttps://communi...

Resolved! Can I do that with Nucleo-L432 or Nucleo F411re boards?

Hello. I have a simple project, but I have a hard time doing my project in STM. The difficulty of the project is that all processes have to work at certain sampling times. As you can see in the picture, I have a robot that is controlled by 2 channel ...

First torque ramp always produces an unexpected strong overshoot

Hello,The first torque ramp command that I start always has a strong overshoot/an unwanted motion. The same command applied right after, with or without having stopped and restarted the motor, behaves as expected.All the next speed ramps are executed...

DC-Motor Control Library for STM32 (VNH5019)

Hello,I would like to drive a simple DC motor with a STM32F446RE.I use the VNH5019 as motor driver.Everything works so far. My only question now would be, is there a ready-to-use library or perhaps a way to embed the component into the software via S...

Resolved! How to run motor in Open Loop

HiI am running on a STM32G071 board, with my own custom HW (standard 3 phase halfbridge). The control is FOC sensorless with 1 shuntI am having problems tuning the motor, but for starters I would like to run the motor at low speed in open loopI can f...

Start-up fails, but gets to appropriate speed.

I have an issue where I keep getting a startup fault. But the motor gets up to the speed its commanded to. I don't have this issue with the demo (IMH07M1) board, but I do with my custom power stage. The only way this would fail is if the pointer t...
