When S32K144 drives the motor, it takes 400 MS for alignment. After the phase current oscillates for 600 mS, the rotational speed starts to appear. Is there an official alignment function? Why there is current oscillation

Hi @zhouqichen,

Thank you so much for your interest in our products and for using our community.

Depending on the motor control technique you are using, whether it is FOC or Six-step commutation, you can consult the ALIGN state in more detail in their respective application notes AN12235 and AN12435.

Hope it helps you. Please let me know if you have more questions about it.

Have a nice day!

Best regards,
Leonardo
