ABSTRACT:
A synchronous control device which is provided with drive motors and a central control unit generating a synchronous reference signal and with which the drive motor is controlled to rotate synchronously with the synchronous reference signal supplied from the central control unit, which is provided with: device motor brakes for braking a rotation of the drive motor; machine home position detectors for detecting a rotation phase of the drive motor; and drive controlling means for controlling a drive motor in such a manner that the drive braking means is activated depending on a stop instruction supplied from the central control unit and a required rotation phase of the drive motor is stored; a comparison between the required rotation phase of the drive motor and the rotation phase thereof is performed at the time of re-start; and a home position alignment of the drive motor is performed at a start time of a subsequent operation.
