S32K144 motor crashes

[zhouqichen]

Hello, using the official routine of S32K144, the motor occasionally crashes during operation. What are the possible causes

Hello,

So I expect the SW is stuck in some exception / routine. Are you using official NXP demo board (which one) or you have custom one.

Did you correctly adapt parameters of SW to your HW if you did any changes?

What is the outcome of debugging. Where is the SW stuck, is it reset? is it in loop? safe mode? etc...

Best regards,

Peter

Hello,

motor occasionally crashes

Hmm, what should I imagine under this condition?

Do the motor burn out? Do the SW get stuck? etc...

Best regards,

Peter
