15.1.1 CNC Control Signals and CNC Status Signals

The CNC control signal and CNC status signal per axis are used for basic axis placement.
For this reason, outputting the optional axis exchange command (G140), optional axis exchange return command (G141),
and basic axis placement return command G142) will not change the axis to which the signals correspond.
The CNC control signal and CNC status signal for all axes are applicable.
The following table lists examples of the CNC control signal and CNC status signal per axis.
[PLC input signal (bit type: X***)]
Signal name
Servo ready First through eighth axis
：
Clamp command First through eighth axis
[PLC input signal (bit type: R***)]
Signal name
Machine position First through eighth axis
：
Actual machining time First through eighth axis
[PLC output signal (bit type: Y***)]
Signal name
Control axis detachment First through eighth axis
：
Clamp complete First through eighth axis
[PLC output signal (bit type: R***)]
Signal name
Ext. machine coordinate system offset data First
through eighth axis
：
Target machining time First through eighth axis
The CNC control signal and CNC status signal per axis include a total of 32 axes (8 axes per part system x 4 part systems).
Signals are allocated to the axes in accordance with the configuration of "#1603 PLCdev_no (axis device allocation number)".
For this reason, using the assigned signals enable commands to be given to a system with 5 or more part systems or to a
system with 9 or more axes per part system.
