Title:
SERVOCONTROL SYSTEM AND METHOD OF SETTING
Document Type and Number:
WIPO Patent Application WO/2003/005141
Kind Code:
A1
Abstract:
An original cam pattern generator (11) generates a first cam pattern for a phase corresponding to one revolution of a cam mechanism. A correction device (14) differentiates the original pattern from the original pattern generator (11) with time, multiplies the differentiated value by a constant, subtracts a predetermined phase from the multiplied value, and generates a corrective cam pattern. The position instruction device (14) adds the corrective pattern to the original pattern to generate a second pattern, and uses the second pattern to generate a position command for a servomotor based on the phase corresponding to one revolution of the cam mechanism.
