Abstract
Disclosed is a synchronous control system for effecting a synchronous and superimposed operation among different channels of a multi-channel-control machine tool. A follow-up error amount (.epsilon.3) of a servomotor responsive to a superimposing instruction is simulated, a difference is determined by subtracting the follow-up error amount (.epsilon.3) to the superimposing instruction from a follow-up error amount (.epsilon.2) of a servomotor for a superimposed operation axis (Z2) and the difference is compared with a follow-up error amount (.epsilon.1) of a servomotor for a synchronous operation axis (Z1) to produce an alarm when the comparison indicates the operation of the servomotors is synchronized and superimposed. With this arrangement, a synchronous error can be checked when a superimposed operation of the servomotors is effected.
