Using interface in PLC axis indexing
When using NC axis in PLC axis indexing, selecting NC/PLC control with "NC control selection n-th axis" signal is required
other than the settings above.
POINT
Multiple NC axes can have the same axis name, although the commands from the machining program are valid when
only one axis is under NC control. When the multiple NC axes are under the control, the machining program will stop
and cause a program error "P11 Illegal axis address" or "P32 Illegal address".
