Abstract
A control system for a servomotor, includes a portion for producing a driving speed controlling signal to be applied to the servomotor, a portion for producing a driving amount controlling signal to be applied to the servomotor, and a signal controlling portion for controlling the state of transmission of the driving speed controlling signal and the driving amount controlling signal to the servomotor, the signal controlling portion being effective to establish a first transmission state in which at least the driving speed controlling signal can be transmitted to the servomotor with a predetermined amplification rate and a second transmission state in which the driving speed controlling signal can be transmitted to the servomotor with an amplification rate smaller than said predetermined amplification rate while the driving amount controlling signal can be transmitted to the servomotor with a predetermined amplification rate.
