Servocontrol system and method of setting
First Claim
1. A servo control system for causing a servo motor 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 above-mentioned correction pattern to the above-mentioned first 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.

Abstract
A servo control system which comprises an original cam pattern generator 11 for generating a first pattern of a cam shape relative to a phase corresponding to one revolution of a cam mechanism; a corrector 14 for differentiating the original pattern of the original pattern generator 11 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 to generate a correction cam pattern; and a position command device 14 for 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.
