This fault diagnosis device: acquires, in a mechanical device in which independent motors are provided as a drive source for operating shafts, the movement position of the operating shafts and the disturbance torque value applied to the operating shafts in individual prescribed periods; and diagnoses an operating shaft to be faulty when the acquired disturbance torque value is greater than a fault assessment threshold value. The fault diagnosis device then executes a fault reassessment, on the basis of inspection results and the maintenance history records, on the operating shaft in diagnosed as being faulty. |
