The position detectors each of which corresponds to each of the motors and each of which is configured to detect position information of each of the motors. All of the plurality of position detectors are connected in series under a control of a first motor control apparatus among the motor control apparatuses. The first motor control apparatus is configured to transfer the position information of the motors read out from the position detectors to other motor control apparatuses among the motor control apparatuses.
