ST Motor Control Workbench and STM32G431CBU6 : 'Communication is closed'

SMutr.1

Hello !

I'm using Motor Control Workbench and the eval board STM32G431CBU6 with a PMSM.

Fisrt, I have used the exemple 'ElectronicsSpeedControl' of ST and I have changed the motor's parameters. After the debug and compilation, the motor makes noise 'bip'. But the motor doesn't run and the fault is 'Over current' with the monitor. This is the same with an another motor.

After, I have generated my own project with the parameters retrieved from Motor Profiler. I did the same Cube MX and 'Generate code'. The eval board connects with the monitor but when I put on 'Start Motor', there is the following message : "Communication is closed, the board doesn't reponse correctly".

I checked every configuration on CubeMX and I don't see differences between the first and the second cases. So why in the second case the communication is closed ?

Moreover, does anyone have any clue how do I solve the problem of overcurrent ?

Thank you very much for support

The question has been moved from the section "Motor Control Hardware" to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
