PURPOSE:To improve the follow-up of a synchronization side motor by detecting the angular acceleration of an instruction side motor and adding the acceleration to the current command of the synchronization side motor. CONSTITUTION:An instruction side motor 101 rotates at a speed in response to the generating speed of a command pulse CMP. A speed feedback pulse FP1 which is proportional to the rotating speed of an instruction side motor 101 is generated from a pulse coder 102, and an active speed voltage signal AVS1 which is proportional to the rotating speed of the instruction side motor 101 is generated from a tachometer generator 103. The pulse FP1 becomes the command pulse of a synchronous motor 210, inputted to the error arithmetic memory 204a of a servo circuit 204, and the actual speed voltage signal AVS1 is differentiated by a differentiator 205 and inputted to an arithmetic unit 204g of the servo circuit 204. The circuit 204 rotates the synchronization side motor 201 in synchronization with the motor 101. |
