ABSTRACT:
A control system for a servo circuit has a speed control unit for controlling the speed of a servo object, a position control unit for controlling the position of the servo object, a switching unit for switching between the speed control unit and the position control unit, a main control unit, and optionally a speed zero detection circuit which compares the real speed and a slice level and detects if the real speed is less than a fixed value. The control system includes a method for producing a target speed using an amount of movement X in an amount of movement d as a remaining amount of movement, and producing a target speed of equal speed for a remaining amount of movement Y. Another method includes controlling the switching of position control of the servo circuit, determining if the conditions for switching to position control are met during speed control, monitoring conditions for switching for a fixed time X after detection of the switching conditions, switching position control when the switching conditions are met for the fixed time X, and returning to determine the switching conditions in accordance with the collapse of switching conditions within the fixed time. An additional method includes outputting a target speed using an amount of movement X as a remaining amount of movement, outputting a target speed of an equal speed of a remaining amount of movement Y, and switching the value of the slice level during the start of movement and after the movement.
