ABSTRACT:
A servo positioning circuit having a speed detection circuit for detecting a real speed from a position signal from a servo object; a speed error detection circuit for generating an error between a target speed and the real speed; a position error detection circuit for generating a position error signal from the position signal; a switching unit for switching connection of the servo object to the speed error detection circuit or the position error detection circuit; and a main processing unit for generating a target speed in accordance with the position signal and controlling the switching of the switching unit. When the servo object nears a target position, speed control by the speed error detection circuit switches to position control by the position error detection circuit. Further, a speed detection gain adjustment unit is included in the speed detection circuit, and the main processing unit changes the speed detection gain of an speed detection gain adjustment unit in accordance with the amount of difference.
