Abstract
A servo control system which comprises an original cam pattern generatorfor generating a first pattern of a cam shape relative to a phase corresponding to one revolution of a cam mechanism; a correctorfor differentiating the original pattern of the original pattern generatorwith respect to time, multiplying the differentiation value by a constant to find a multiplication value, and subtracting a predetermined phase from the multiplication value to generate a correction cam pattern; and a position command devicefor adding the above-mentioned correction pattern to the above-mentioned original pattern to generate a second pattern and generating a position command of the above-mentioned servomotor based on the phase corresponding to one revolution of the above-mentioned cam mechanism using the second pattern.
