Servo controller
First Claim
1. A servo controller for synchronously controlling a plurality of drive sources, comprising:
- a correction data calculation means for calculating correction data to correct a positional deviation of a slave side drive source according to a synchronization error which is a difference between a positional deviation of a master side drive source to drive one drive axis and a positional deviation of the slave side drive source to drive the other drive axis, wherein the master side drive source and the slave side drive source are synchronously controlled when the correction data is added to the positional deviation of the slave side drive source.

Abstract
There is provided a servo controller for synchronously controlling a master side drive source to drive one drive axis and a slave side drive source to drive the other drive axis. The servo controller includes a correction data calculation means for calculating correction data to correct a positional deviation of a slave side drive source according to a synchronization error which is a difference between a positional deviation of a master side drive source and a positional deviation of the slave side drive source, in which the correction data is added to the positional deviation of the slave side drive source.

11. A servo controller for synchronously controlling a plurality of drive sources, comprising:
-
a selection means for selecting one of the synchronization error, which is a difference between a positional deviation of a master side drive source to drive one drive axis and a positional deviation of the slave side drive source to drive the other drive axis, and the positional deviation of the slave side drive source; and
a correction data calculation means for calculating correction data to correct the positional deviation of the slave side drive source according to one data selected by the selection means, wherein the correction data is added to the positional deviation of the slave side drive axis so as to make the positional deviation or the synchronization error come close to zero.
