Abstract

PURPOSE:To prevent the quick change in the armature current of a servomotor by continuously decreasing the speed pattern at the vicinity where acceleration is changed to deceleration in time sequence, and obtaining a step shaped pattern in a low deceleration region. CONSTITUTION:An analog multiplexer is constituted by an analog switch group 11 and a decoder circuit 12 wherein one switch in said switch group 11 is selected and conducted based on an inputted digital signal. An impedance Z7 which is selected by a switch S7 is formed by resistors R7a and R7b and a capacitor C7. An impedance Z6 selected by a switch S6 is formed by resistors R6a and R6b and a capacitor C6 like the impedance Z7. Impedances Z8 and Z5-Z1 are formed only by resistors. In this constitution, occurrence of vibration can be prevented in a transient period without degrading the response of the servomotor.
