PURPOSE:To effect an changing operation in accordance with the change of a mold or the like simply in a short period of time by a method wherein a means for setting the reference rotating speed of a servomotor based on the output signal of a rotary encoder provided on the servomotor is provided. CONSTITUTION:A motor speed setter 94 comprises a movable disc moving stroke setter 96 and a speed to acceleration and deceleration ratio setter 98. In this case, the movable disc moving stroke setter 96 is for setting and memorizing the maximum moving distance of a movable disc with respect to a fixed disc by a digital value while the speed to acceleration and deceleration ratio setter 98 is made capable of setting the reference rotating speed of a servomotor 14 in corresponding to the moving distance, the moving direction or the like of the movable disc. The moving speed of the movable disc, moving speed of an injection cylinder and the like may be set easily by the simple operation of setting set values in respective setters 96, 98 only. |
