ABSTRACT:
Diagnosis of servo motor driven drive train problems based upon changes in the rotational velocity of the servo motor as electrically operable drive line components are selectively engaged. The unloaded (unloaded) rotational velocity of a servo motor is determined, a drive train component that couples a load to the servo motor is energized, the change in the rotational velocity of the servo motor caused by engaging the drive train component is determined, and, if the servo motor rotational velocity falls outside of a predetermined limit the drive line fault that causes that rotational velocity to fall outside of that limit is identified. Beneficially, the status of the drive train is sent to a remote location using a data link.
