Abstract

A motor control device comprising a motor control unit that, on the basis of an operation command signal for driving a motor and a feedback signal, from an encoder, corresponding to the operation of the motor, generates a command value pertaining to the operation of the motor in accordance with a prescribed feedback scheme so that the operation of the motor follows the operation command signal, wherein interrupt processing of a drive signal is executed by an interrupt unit on the basis of a comparison result of two items pertaining to a prescribed feedback value calculated using the feedback signal from the encoder, and to a state calculation value that is calculated on the basis of the operation command signal and that pertains to an operating state of the motor comparable with the prescribed feedback value.
