14.35.3.1 Synchronous Control

Synchronous control can be performed to the axis where NC axis/PLC axis switchover is performed either in NC axis mode or
PLC axis mode.
To execute the synchronous control using the NC axis/PLC axis switchover target axis, both master and slave axes where the
synchronous control is performed need to be the NC axis/PLC axis switchover target axes.
When the synchronous control using the NC axis/PLC axis switchover target axis is started, both master axis and slave axis
need to be in NC axis mode. If the synchronous control start is commanded while either of the axes is in PLC axis mode, the
operation error (M01 1036) occurs.
During the synchronous control between NC axis/PLC axis switchover target axes, the control modes of master axis and
slave axis need to be matched. When the movement command (automatic operation/manual operation) is issued to the
master axis as NC axis, the control modes of both master and slave axes need to be NC axis mode. When commanded to the
master axis as PLC axis, the control modes of both master and slave axes need to be PLC axis mode. If the control modes
are not matched, the alarm occurs when the movement command to the master axis is issued.
