ABSTRACT:
A control system for a machine includes a pulse generator for generating a pulse signal synchronized with the speed of drive of the machine and a programmed control device for receiving the pulse signal and controlling the sequence of operation of the machine thereby to synchronize the control operation of the control device and the actual operation of the machine with each other. For this purpose a program of the programmed control device is so designed that a control routine for executing a process necessary to control the machine and a synchronizing routine for controlling the timing at which said control routine is to be started are executed continuously and repeatedly. The routine of the program are so associated with the pulse generator that the number of pulses generated at a speed corresponding to the normal run of the machine during the time equal to the sum of the control routine and the synchronizing routine is at least two. The control routine is started immediately after the generation of the pulse during the execution of said synchronizing routine has been detected.
