SYNCHRONOUS CONTROL INITIAL POSITION

The initial position for synchronous control is explained in this chapter.
Configure these settings for situations that require initial position alignment for synchronous control.
5.1
Synchronous Control Initial Position
The following synchronous control monitor data can be aligned to a set position when starting synchronous control, as the
initial position for synchronous control.
The alignment to a synchronous control initial position is useful for restoring a system based on the last control status along
with restarting synchronous control after canceling midway.
