The axis in PLC axis mode cannot be specified to the chopping axis. The operation error
(M01 0154) occurs when the chopping starts.
The axis in chopping cannot be switched to PLC axis mode. If NC axis/PLC axis switcho-
ver request is turned ON, the operation error (M01 1250) occurs.
The axis in PLC axis mode cannot be specified to the tool rotary axis. The operation error
(M01 0005) occurs when the polygon starts.
The tool rotary axis cannot be switched to PLC axis mode while the polygon is executed.
If NC axis/PLC axis switchover request is turned ON, the operation error (M01 1250) oc-
curs.
The axis in PLC axis mode cannot be specified to the workpiece axis. The operation er-
ror (M01 0005) occurs when the hobbing starts. Also, the axis in PLC axis mode is out
of the subject of hob retract (hob retract is not performed).
The workpiece axis cannot be switched to the PLC axis mode while the hobbing is exe-
cuted. If NC axis/PLC axis switchover request is turned ON, the operation error (M01
1250) occurs.
High-speed machining mode II or High-speed high-accuracy control II cannot be execut-
ed in the part system including the axis in PLC axis mode. The program error (P29) oc-
curs when High-speed machining mode II or High-speed high-accuracy control II starts.
The axis in the part system where High-speed machining mode II or High-speed high-
accuracy control II is being executed cannot be switched to the PLC axis mode. If NC
axis/PLC axis switchover request is turned ON, the operation error (M01 1250) occurs.
The axes can be switched with mixed axis control either in NC axis mode or PLC axis
mode.
After switching the axes with mixed axis control, the switching axis can be switched to
NC axis mode or PLC axis mode.
Even when the axis in PLC axis mode is moving, the switching axes with mixed control
can be performed.
Whether in NC axis or PLC axis mode, the axes can be switched with the arbitrary axis
exchange control.
After switching the axes with the arbitrary axis exchange control, the mode of the
switched axes can be changed to NC axis or PLC axis.
When the arbitrary axis exchange command is given during PLC axis mode while the
target axis is moving, the exchange is performed immediately if the exchange is between
part systems, or is performed after the axis movement is completed if the exchange is
within a part system.
Even if the axis to switch is a non-control axis, the mode can be switched between NC
axis and PLC axis.
