  • Patent number: 11988503
    Abstract: A failure diagnostic system of a motor encoder is disclosed and includes a motor, an encoder, a servo driver, and a safety module. The servo driver controls the motor through a current command. The safety module continuously obtains a feedback position of the motor through the encoder. When the safety module determines based on the feedback position that the current state of the motor is consistent with a pre-determined disturbance condition, the safety module requests the servo driver to output an additional current command to disturb the motor. Next, the safety module determines whether the encoder is failure based on a variation of following feedback position.
