Abstract:
1. A servo control device, comprising: 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, said logical arithmetic section outputting the current command to the current supply unit alter converting the current command by a digital logic process on the basis of the drive current value by using a custom large-scale integrated circuit, wherein the logical arithmetic unit includes: an input register which introduces and holds the current command; a feedback register which introduces and holds the drive current fed back from the first detector; and a current control arithmetical unit for correcting the current command with reference to a difference between the current command from the input register and the drive current value from the feedback register.
