Hi,

 

when I set PWM signal 100% duty, the motor's full speed is 2800rpm, and the current is about 37A,   I adjust PWM  duty

 

= 10%  let motor to stop, then i will  adjust PWM  duty = 100% suddenly,  Repeat a few times(run--stop---run------)as

 

soon as possible, after this GDU will broken. After I changed a new MCU, it will work.

 

what reasons can cause this problem?
