PROBLEM TO BE SOLVED: To synchronize two shafts with each other even when abnormality occurs in communication lines between a control device and motors.SOLUTION: In a first synchronization system of a synchronization control device (1), movement instructions synchronized with each other for a first motor (23) and a second motor (13), which are generated by a movement instruction generation part (9) are supplied to a first amplifier (22) and a second amplifier (12) via a first communication line (11) and a second communication line (21) respectively. In a second synchronization system switched from the first synchronization control system, the first motor (23) is decelerated by a deceleration instruction generated by a deceleration instruction generation part (29), and the second motor (13) is decelerated synchronously with the first motor by a movement instruction generated on the basis of a position feedback value which is supplied to the second amplifier (12) via a third communication line (31) and is controlled by the first motor (23). |
