Operation procedure
 When starting synchronous control
(1) Set the control modes of both master and slave axes to NC axis mode.
(2) Start synchronous control.
At this time, if either of the axes is in PLC axis mode, the operation error (M01 1036) occurs.
 When moving the axis in PLC axis mode
(1) Set the control modes of both master and slave axes to PLC axis mode.
(2) Issue PLC axis control command to master axis.
-> Slave axis is moved synchronizing with master axis.
When PLC axis command is issued to slave axis, the alarm No. 21 is output to PLC axis control information data.
If either of the axes is in NC axis mode, the alarm No. 20 is output to PLC axis control information data.
 When moving the axis in NC axis mode
(1) Set the control modes of both master and slave axes to NC axis mode.
(2) Issue NC axis command (automatic operation/manual operation) to master axis.
-> Slave axis is moved synchronizing with master axis.
If NC axis command (automatic operation/manual operation) is issued to slave axis and the automatic operation com-
mand is issued, the program error (P32) occurs. The manual operation command is ignored.
When either of the axes is in PLC axis mode, the program error (P32) occurs if the automatic operation command is
issued, and the operation error (M01 0005) occurs if the manual operation command is issued.
 When moving the axis in correction mode
(1) Set the control modes of both master and slave axes to NC axis mode.
(2) Select the handle mode or manual arbitrary feed.
(3) Turn ON the correction mode.
-> When the correction mode is valid, "CORRECTION MODE" is displayed at the display position of control mode.
At this time, when either axis is in PLC axis mode, the correction mode is invalid.
(4) Issue NC axis command (manual operation) to one of the master axis or slave axis which is to be moved.
-> Only the selected axis of either master or slave axis is moved.
 When canceling synchronous control
(1) Complete the movement of both master and slave axes.
(2) Cancel synchronous control.
 When two sets of synchronous control is executed, the control modes of those two synchronous control do not need to be
matched.
 When zero point return is executed for an axis that is subject to synchronous control while the axis is in PLC axis mode, the
alarm No. 21 is output to the PLC axis control information data, whether or not the synchronous control is valid.
 Even when both master and slave axes are in PLC axis mode, synchronous error automatic correction function at servo ON
can be performed.
