Abstract
Provided is a motor control device comprising a motor control unit and a safety monitoring unit. The motor control unit switches a rotation direction of a motor with respect to an input instruction in accordance with a set motor-control rotation-direction specified value. The safety monitoring unit monitors, on the basis of a position or speed of the motor, a state of the motor deviating from any one of a plurality of safety state conditions prescribed by a plurality of set safety-monitoring parameter values, and the safety monitoring unit can treat the plurality of safety-monitoring parameter values as a value of a case when the rotation direction of the motor is a first direction or as a value of a case when the rotation direction of the motor is a second direction reverse to the first direction. The motor control device has a safety function being flexible in programming.
