Abstract

This motor control device is provided with a motor control unit which, on the basis of an operation command signal for driving the motor and a feedback signal from the encoder corresponding to motor operation, generates a command value relating to operation of the motor in accordance with a prescribed feedback method such that operation of the motor follows the operation command signal. The occurrence of an error is determined on the basis of the result of comparing a prescribed feedback value, which is calculated from the feedback signal from the encoder, and an operation command value, which is calculated from the operation command signal, and, on the basis of this determination result, interruption processing of the drive signal is performed. By means of this configuration, it is possible to improve safety performance of the motor control device without hampering the safety performance of the encoder.
