Abstract
There are provided a load state diagnosis device and a load state diagnosis method for a servomotor. A PLC diagnoses the load state of the servomotor which rotationally drives a rotary tool in a predetermined rotational drive direction at a constant speed. The PLC includes a detection part that detects the rotational direction of a torque acting on the servomotor, a determination part that determines whether the rotational direction of the torque detected by the detection part is consistent with the predetermined rotational drive direction, and a load index output part that outputs a load index indicating the load state of the servomotor based on a determination result of the determination part.
