Hi Christian,1. Is it possible there are higher peaks than the commanded motor current? The best method is to examine the motor current with a current probe when the FAULT occurs.2. What do you mean...

Thanks for the Reply Nick, 1. Am not sure but it might be possible but it overcurrented at only around 80 to 90 % duty which led me to believe it has to do with the PWM. It might not be a OC but it is...
