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 interfa...

What to change in FOC code for lower inertia?

I have a BLDC motor running reliably with FOC code on a STM32G431 MCU. For unrelated mechanical reasons we need to drop our inertia by about 4x from where it is running today. For the speed loop I fully understand lowering inertia raises the loop ga...

STEVAL-ESC001V1 communication protocol

Dear All,Does anybody have any documentation about this motor controller's communication protocol?I would like to use this controller - as it is, connecting a STM32 via UART (not PPM, since I'd like to get the measured data back), but I could not fin...

Resolved! Nucleo power supply when plugged on X-NUCLEO-IHM08M1

Hello,I am using an X-NUCLEO-IHM08M1 board plugged on a G431 Nucleo board and I have a question regarding the Nucleo power supply.In the IHM08 Quick Start Guide it is noted that the JP5 PWR jumper must be set to E5V (powered from morpho connector), h...

Resolved! ADC not working with NUCLEO-G431RB.

NUCLEO-G431RB + X-NUCLEO-IHM07M1MCWB 5.Y.3 + STM32CubeIDE 1.7.0Maxon motor combination: 200142 + 166935 + 673026I have created a project to drive a BLDC motor with the above mentioned equipment, I was able to create a basic project to drive the ...

Timer pin assignment with STM32CubeMX for BLDC motor control

I will use the STM32G491VC MCU, and the Timer input XOR function for interfacing with Hall sensors (Ref. Manual RM0440, page 1167). Figure 353 (page 1169) shows the six half-bridge control signals for the motor phases (tim_oc1, tim_oc1n, etc.).Questi...

I will create code for discovery kit 'B-G431-ESC' as described in UM2516 chapter 6.1 step 2 and 3 but I get error when compiling with STM32CubeIDE . Is there a more detailed description for generation or an example for this evakit?

I use MCSDK v5.4.7 and STM32CubeIDE 1.6.1. Project generation with MCSDK is successful but when I try to build code with the IDE it ends with fatal error "sto_cordic_speed_pos_fdbk.h: No such file or directory". Run code generation with an other exam...

I want to estimate the motor paramters(e.g:Resistance,inductance etc) using my ST board.

But i don't want to use Motor profiler neither i want to enter the values to MC WB manually.How can paramters be estimated ?

My STEVAL HKI001V2 is not able to communicate with SDK 5.Y.1 and SDK 5.Y.2 It can communicate with SDK 5,4,6 , What is a reason I am also not able to find the STEVAL HKI001V2board set on the Motor profiler list of boards Is this board set supported?
