We have had a talk with your FAE Linda Zhang and Leon Yan. They suggested us to ask you for help. In order to solve our problem as soon as possible, it's very kind of you to if you could help us review our schematics.

    As we have replied to you, you should check if the below items are right and help to provide more tested information (like motor current waveform) that may help us resolve this.
    1. Check current/voltage feedback circuit using lab03 and lab04.
    2. Check the maximum voltage/current in user.h
    3. Set correct identification current and frequency based on motor specification.

    I've merged your newest thread with this one as the two topics seem to be the same. For further discussion on this topic, please keep to the following thread and we would like to close this thread. Thanks.
