A synchronous control apparatus to synchronously control a plurality of motors with respect to a control subject includes a command device and a plurality of motor control devices. The control subject includes the motors, a plurality of position detectors configured to detect a plurality of position information of the motors respectively, and at least one coupler connecting movable axes of the motors. The command device includes a first position controller which is configured to compute a work position based on the position information detected by the position detectors and which is configured to compute, based on a difference between a position command and the work position, a new position command. Each of the motor control devices includes a second position controller configured to compute commands to drive the plurality of motors based on a difference between the new position command and the position information.
