Abstract
A servo control device includes 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 which introduces a current command determining the drive current for controlling the drive speed of the drive unit to move the target to be controlled to a predetermined position, and which 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 correcting the current command by a digital logic process on the basis of the drive current value.
