PURPOSE:To efficiently control various servo motors by setting an interrupt period in response to the rated value of a servo motor to be controlled and driven. CONSTITUTION:An interrupt period of a servo CPU10 is varied at a servo controller side to efficiently control both AC and DC servo motors. Thus, the CPU10 transfers high speed data through a common RAM13 in an NC machine together with a main CPU12, and when controlling to drive a plurality of servo motors, the interrupt period can be set in response to the rated value of the servo motor, the drive control signal in response to the drive torque can be supplied, the main CPU and the exclusive servo CPU at every servo motor are coupled to efficiently control to drive various servo motors.
