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...

About the algorithm selection of sensorless PMSM

Hi ST community，I tried to use STM32CubeMX for motor control of sensorless PMSM. I am confused about the Speed Sensing module. There are three modes of sensorless: Observer PLL, Observer Cordic, HFI+Observer, what is the trade-off between them? HFI+O...

Resolved! At motor BRK interrupt handler, TSK_SafetyTask() should be called instead of MC_Scheduler() to immediately execute fault processing?

(Environment)MC_SDK 5.Y.3 + STM32CubeMX 6.3.0 with HAL + IAR EWARM 8.5(Hardware)custom board based on F446RE + custom power board + Low Voltage BLDC motor with Encoder(Control Mode)Speed Control(What I found)In "stm32f4xx_mc_it.c", there is TIMx_BRK_...

PMSM hardware with MCSDK v6

Hi good day, i have a fanuc AC PMSM 140v, 6NM, 4.6A, 1kw, 2000ppri see the tool hardware and think what the follow kit is convenient:1.- Nucleo G431RB2.- X-nucleo IHM09M13.- STEVAL-IPM30Bbut i see MCSDK v6 no support this hardware, then I ask some ge...

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...
