MCT8329EVM: Auto stop

Part Number: MCT8329EVM
Other Parts Discussed in Thread: MCT8329A

Tool/software:

Hello,

I have some issue with my brushless motor, i am still tuning to have soft start and be able to stop the motor with the brake switch of the eval board (stop working).

For now, motor sometime not started every time, once it started he can run several second or 1/2 minutes but stop with a loss of sync fault or abnormal speed... is it more due to limit too low or initial setting ? 

What can I adjust or be worry ?

  • Join my last setting file, maybe you will see some incompatibility... work well but still have stop and issue on start

  • Hi Kevin,

    We will verify and get back to you.

    Thanks and Best Regards
