Running MCSDK 5.0.3 with STM32F446 Nucleo and X-NUCLEO-IHM08M1 & Hall sensors

Hello,

I am working on running a 250W Hub motor with the following setup:

STM32F446 Nucleo

X-NUCLEO-IHM08M1

3 Hall sensors

 

unfortunately the Motor Profiler fails to profile the motor I am using and so I measured and entered all Parameters - as good as I could - manually into the Motor control workbench.

 

Now when I try to start the motor with the Monitor in Workbench, I usually get a short movement of the motor which stops abruptly with an over current fault. This seems technically impossible as I use a power supply limited to 3A, while my current limit in ST software is set to 10A. Sometimes the fault doesn't appear but the motor makes squeaking noise and draws around 0.5-1A from the supply.

 

Does anyone have an idea what my fault could be?

Maybe wrong motor parameters? Or a fault related to the current sensor?

 

Many Thanks,
