B-G431B-ESC1 Motor Profiler "Over Voltage"

[Marc1]

I'm using ST Motor Pilot V1.1.5 with eval board B-G431B-ESC1.

Motor: IBL-100SW-1 http://www.itomotor.com/product/detail/67.html

Motor Profiler Configuration:

Pole Pairs: 3

Max Speed: 2000 RPM

Max peak current: 5 A

Magnetic: I-PMSM

ld/Lq: 1

After starting the profiler, the motor tries to start. But then, after a few seconds the profiler stops and shows the fault message "Over Voltage". This happens even if supply voltage is only 12 V. The oscilloscope shows that PWM peak voltage starts with 12 V and then rises up until more than 30 V between GND and motor phases.

Hello @Marc1 ,
I would be happy to help you if you still need. Have you tried with the latest version of MCSDK 6.1.2. If not, have you tried lowering the amperage on the profiler?
Regards

Hello @Zied b.,
I used the latest version of MCSDK at that time. It was MCSDK 6.1.1. I have tried lowering current and voltage.

Hello @Marc1 
We made some changes on 6.1.2 can you try and tell me if it works better?
