Abstract

A motor control system includes a mechanical apparatus configured to be driven by a motor, a position detector configured to detect position information of the motor, circuitry configured to control the motor, at least one sensor configured to detect information relating to at least one of the mechanical apparatus and the motor, and an input and output device including input-and-output connectors. The position detector and the input and output device are connected to the circuitry through a same communication path. The at least one sensor is connected to the input-and-output connectors of the input and output device. The position information is configured to be transmitted from the position detector to the circuitry. The information relating to the at least one of the mechanical apparatus and the motor is configured to be transmitted from the at least one sensor to the circuitry through the input and output device.
