Abstract
A motor control device includes: a control processing unit that controls driving of a motor based on a command signal input from a controller so as to command an operation of the motor and a detection signal which is a detection result of the operation of the motor; and an abnormality determining unit that detects an abnormality in the controller, the motor control device, and the motor based on the command signal, the detection signal, and a control signal generated in the motor control device and that determines a level of repeatability of the detected abnormality based on a predetermined criterion. The control processing unit transitions from a normal mode to a specific abnormality alarm mode when the abnormality determining unit determines that an specific abnormality having high repeatability has occurred.
