PROGRAMMING 18. SPECIFYING THE LASER FUNCTION
When inputting the signal from a sensor which is installed at the end of
the nozzle of the laser processing system to detect the distance from the
workpiece, the CNC issues a move command for the Z–axis (or W–axis)
to obtain a specified distance between the nozzle and the workpiece.
For details, refer to “FS16i–LB Connection Manual” (B–63663EN).
S Set gap control mode
G13 P__ (R__L__);
S Cancel gap control mode
P__: Reference displacement value
R__: Gap amount
L__: Gap controlled axis (switching between Z– and W–axes)
When G13 is specified, the CNC enters the gap control mode to control
the distance between the cutting nozzle and workpiece according to the
signal input from the gap sensor so that the distance specified by P or R
can be obtained.
When G14 is specified, or when a reset is made, the gap control mode is
In the gap control mode, the CNC performs velocity control
instead of position control, which is the control method
usually used. Therefore, programmed move commands
(G00, G01, and so on) and manual move commands must
not be issued for the Z–axis in the gap control mode.
