Motor Profiler - Motor Won't Spin - (from MC Workbench 6.2.0)

[Gary_Baldy]

Hi,

This is my first post on the forum so my apologies if I’m doing something wrong.

OS:

Windows 10 64-bit

Software:

STM32CubeIDE 1.14.1

Motor Control Workbench 6.2.0

ST Motor Pilot v1.2.4

Hardware:

Dev Kit:                      P-NUCLEO-IHM002

Control Board:            NUCLEO-F302R8

MCU:                          STM32F302R8

Power Board:              X-NUCLEO-IHM07M1

Motor:                         Bull Running BR2804-1700kv

Problem Description:

The motor does not spin when I run the profiler using Motor Pilot v1.2.4. I can see the motor momentary jerks but it doesn’t spin and consequently the profiler fails. I have followed the profiler setup in ST Motor Pilot v1.2.4 > Help > Profiler Documentation. The profiler firmware is generated. I have compiled and uploaded the generated code with STM32CubeIDE 1.14.1. No errors or warnings are generated. When I start the profiler it hangs at 28% - the motor never rotates. See attached screenshots

In contrast I have no problems when using the Motor Pilot instead of the Motor Profiler. With the Motor Pilot the motor spins and I can adjust the speed from the GUI.

Questions:

1. What is the problem stopping the Motor Profiler from working?
2. How do I fix this problem?
3. It appears that the code generated for the Motor Profiler (tick the "Motor Profiler" feature into the "Application configuration") does not work with the Motor Pilot – and code generated for the Motor Pilot does not work with the Motor Profiler. Is this correct? I didn’t see this mentioned in the documentation.

Thanks:

If anyone from ST sees this message then I want to say a sincere thank you to ST for providing all the excellent tools, software and documentation – for free! A very intelligent business decision and I’m grateful.

Hello @Gary_Baldy,

Firstly, thank you for your message.
There is a known issue on WorkBench 6.2 profiler (profiler functional for STM32G4 series only), could you please try with 6.2.1 version?

[Gary_Baldy]

Many thanks for your reply!

I installed 6.2.1 and re-generated the code (using the project attached to my first post). When I compiled the new code I got many errors as shown below so cannot test the profiler. Most seem to state 'undefined reference'. I've tried to solve this but haven't succeeded.

Can you help?

Hello Gary_Baldy,

I don't know if this is your case, but it feels like you generated a project with MCSDK 6.2.0, then opened the same project with MCSDK 6.2.1 and re-generated that project into the same folder without changing its name. Am I right ?
In any case, please refrain from doing this, as it generally causes a few issues. Please create a new project or save your project in a different folder / with a different name to ensure a correct generation. If the issue persists, please make sure your CubeMx, CubeIDE and Firmware package are up to date. I generated your project using MCSDK 6.2.1, CubeMX v6.11.0, CubeIDE v.1.13.2 and Firmware package v1.11.4 and had no issue.

[Gary_Baldy]

Yes, you are correct I opened an existing 6.2.0 project in 6.2.1 and re-built it.

I followed your advice, updated all software components and created a new MC project and now the profiler works.

Many thanks for your assistance!
