4 Explanation of Interface Signals
4.1 PLC Input Signals (Bit Type: X***)
Cont. Signal name
A NC axis/PLC axis switchover invalid status
[Function]
This signal indicates that the NC axis/PLC axis switchover is disabled on the axis that is subject to the NC axis/PLC axis
switchover.
This signal is available for each control axis.
[Operation]
This signal turns ON when the axis for which the NC axis/PLC axis switchover is valid is under the following conditions.
When the NC axis/PLC axis switchover is performed while this signal is ON, the operation error (M01 1250) occurs.
 While the axis is moving(*1)
 When the movement is stopped by the override zero or feed hold
 During the servo OFF
 While the axis is being removed
 While the axis is stopped for interlock
 During the current limit
 During the droop cancel
 During the H/W OT or soft limit
 During the manual machine lock
 The reference axis or superimposed axis that is under the control axis superimposition
 The reference axis or synchronized axis that is under the control axis synchronization between part systems
 The chopping axis during the chopping
 The rotary tool axis during the tool spindle synchronization II (polygon)
 The workpiece axis during the tool spindle synchronization II (hobbing)
 The axis of the part system which is during the high-speed machining mode II/high-speed high-accuracy control II
(*1) When a movement command is given to multiple axes in the same program block, even if the movement of the swi-
tchover target axis is completed and stopped, the switchover is disabled if the other axes are still moving.

(2) NC axis/PLC axis switchover request (NPCHGREQ1 to 8: YBC0 to 7)
Cont. Signal name
A NC axis/PLC axis switchover n-th axis in process
[Function]
This signal notifies that the NC axis/PLC axis switching axis is in a controllable state as a PLC axis.
This signal is available for each control axis.
[Operation]
This signal turns OFF while the NC axis is controlled and turns ON while the PLC axis is controlled.
