1. A servo control system for causing a servomotor to perform operation equivalent to a cam mechanism, the servo control system comprising:

  • pattern generation means for generating a first pattern of a cam shape relative to a phase corresponding to one revolution of the above-mentioned cam mechanism;

    correction means for differentiating the first pattern of the pattern generation means with respect to time, multiplying the differentiation value by a constant to find a multiplication value, and subtracting a predetermined phase from the multiplication value, thereby generating a correction pattern; and

    position command generation means for adding the correction pattern to the first pattern to generate a second pattern and generating a position command for the servomotor based on the phase corresponding to one revolution of the cam mechanism using the second pattern.
