ABSTRACT:
A servo control device comprises a current supply unit for supplying a drive unit with a drive current for driving a target to be controlled, a first detector for detecting at least the drive current value, and a logical arithmetic section. The logical arithmetic section introduces a current command determining the drive current for controlling the drive speed of the drive unit to move the target to a predetermined position, and introduces the drive current value fed back from the first detector. The logical arithmetic section outputs the current command to the current supply unit after converting the current command by a digital logic process on the basis of the drive current value by using a custom LSI.
