摘要
The failure diagnosis apparatus of a speed reducer of the present invention is provided to reduce the rotational power of the motor to the mechanical device 11 driven by the motor 14 and transmit it to the operating unit 12 of the mechanical device. As the device 1, an acceleration/deceleration period during which the operation of a mechanical device is accelerated/decelerated is specified, and based on a change in the frequency spectrum of the motor current with respect to a change in the rotation speed of the motor in the acceleration/deceleration period, a sign of a failure in the reducer It is configured to determine whether there is a presence or not.
