PURPOSE:To improve the degree of freedom for control to prevent the abnormality of the working state of a servo motor by providing a jump program into a loop for feedback control and performing the control based on the jump program when the jump conditions are satisfied. CONSTITUTION:The control data includes a working command program containing a set rotational speed, etc., a deciding command program like a jump condition program, a program obtained after jump, etc. Then the control data is supplied through a set input device 10 and stored in a control data memory 26. While a ROM 14 produces a control pattern based on said control data and stores the pattern into a control pattern memory 28. A program memory 24 of the ROM 14 stores a processing logic for execution of the control to the rotational speed, etc., based on a control pattern. A CPU 12 applies the driving control to a servo motor 18 according to the processing logic of the memory 24. If the rotational position of the motor 18, for example, exceeds the jump conditions during the drive control of the motor 18, the CPU 12 performs its control based on a jump program.
