MC_ClearFaults

Description

The MC_ClearFaults function sends a request to the drive to clear any drive faults that exists.

• 
  

• The condition causing the drive fault has to be corrected before calling this function. If the fault condition still exists when this function is called, this function sends a request to the drive but the drive faults remain.

• 
  

• This function does not reset axis errors. MC_ResetError is required to reset axis errors and possibly to re-enable or turn power on to the servo axis after the fault condition is cleared.
