PROBLEM TO BE SOLVED: To improve driving position accuracy for a driving system to be driven as prescribed by a servo motor to be driven under feedback control. SOLUTION: Concerning this control method for servo motor at the driving system with a servo motor 2 as a driving source, this method is provided with a 1st encoder 2 for detecting the turning speed of the servo motor while being directly connected to the motor and a 2nd encoder 4 for detecting the moving position of object to be driven in the driving system. Based on the output signal of the 1st encoder 3, feedback speed control is performed for speed control and based on the output signal of the 2nd encoder 4, feedback position control is performed for the moving position control of the driving system. |
