AXIS SELECT OUTPUT
[Function]
This signal indicates that motion command is issued to the control axis.
[Operation]
This signal turns ON and OFF as follows:
(1) Automatic operation
The signal is ON while the motion command is issued to the end of movement, or to when
automatic operation pause turns ON.
(2) Manual operation
• For JOG mode
The signal is ON while "Feed axis select" signal (+Jn and -Jn) is ON.
• For HANDLE mode
When "Handle axis No." signal (HS11 to 116) and "Handle valid" signal (HS1S) have been
selected, "Axis select output" signal for the axis specified by the "Handle axis No." signal is
ON.
• For INCREMENTAL mode
The signal turns ON when "Feed axis select" signal turns ON, and turns OFF when the
specified motion is completed.
• For MANUAL RANDOM FEED mode
The signal turns ON when "Strobe" signal (CXS8) turns ON, and turns OFF when the
specified motion is completed.
• For REFERENCE POINT RETURN mode
The signal is ON while "Feed axis select" signal (+Jn and -Jn) is ON. After "Reference point
return near-point detect" signal is detected, and the motion speed changes to approach
(creeping) speed, the "Axis select output" signal remains ON until the motion stops at the
reference point, even when "Feed axis select" signal turns OFF.
(3) Other conditions
• The signal can turn ON even during machine lock (Z-axis is in cancellation). However, it
does not turn ON during machine lock in manual operation mode.
• The signal remains ON even when motion stops due to feedrate override set at 0%, manual
control feedrate set at 0 mm/min, or 0 inch/min.
• Interlock does not affect status of this signal (the signal remains ON, or turns ON).
• "Servo OFF" signal does not affect status of this signal.
• The signal cannot be turned ON by G04 and G92.
• The signal turns OFF with controller reset & rewind, or emergency stop.
