SERVO CONTROL APPARATUS THAT PERFORMS LEARNING CONTROL BY CHANGING REFERENCE AXIS
First Claim
1. A servo control apparatus for a machine that performs machining by driving and controlling a servo motor on the basis of a position command and by causing a plurality of synchronizing axes to operate cooperatively in synchronized relationship with a reference axis, the servo control apparatus comprising:
- a position detection unit for detecting at least one of the position of the servo motor and the position of a driven body;
a position error calculation unit for calculating an error between the position command and the position detected by the position detection unit;
a reference axis position acquisition unit for acquiring the positions of a plurality of reference axes;
a reference axis selection unit for selecting one reference axis on the basis of a machining condition of the driven body from among the plurality of reference axes whose positions have been acquired; and
a learning control unit for performing learning control using an angle synchronization method, on the basis of the error and the position of the selected reference axis.

Abstract
A servo control apparatus for a machine that performs machining by causing a plurality of synchronizing axes to operate cooperatively in synchronized relationship with a reference axis, the servo control apparatus comprising: a position detection unit for detecting at least one of the position of the servo motor and the position of a driven body; a position error calculation unit for calculating an error between the position command and the position detected by the position detection unit; a reference axis position acquisition unit for acquiring the positions of a plurality of reference axes; a reference axis selection unit for selecting one reference axis based on a machining condition of the driven body from among the plurality of reference axes whose positions have been acquired; and a learning control unit for performing learning control using an angle synchronization method, based on the error and the position of the selected reference axis.
