A motor control system includes a motor, and a motor control apparatus including first processing circuitry that, based on a driving state quantity of the motor, controls driving power supplied to the motor, safety request input receiving circuitry through which a safety request signal is input from outside the motor control apparatus, safety cooperation input receiving circuitry through which a safety cooperation signal is input from outside the motor control apparatus, safety cooperation output circuitry through which the motor control apparatus outputs the safety cooperation signal to outside the motor control apparatus, and second processing circuitry that, upon input of at least one signal among the safety request signal and the safety cooperation signal, monitors a relationship between a predetermined motion monitor pattern and the driving state quantity and outputs the safety cooperation signal.
