DRV8701EVM: PWM control

Hi Cherry,

Could you please further describe the "stuck condition":

- Is the motor stalling after start-up?

or

- Is the motor not enabling at all?

The DRV8710E has a PH/EN control interface and motor control will depend on the bridge control.

Half H-Bridge mode:

Hi David,

Thank you for the support.

It is more like a motor spin issue, it will get stuck as it rotates.

Thanks and regards,

Hi Cherry,

If the settings above have not solved the issue, could you please provide the following:

- Which MOSFETs are being used?

- What is the IDRIVE setting ?

If the issues have been solved from the earlier post, please disregard the following questions.

Best,

David
