16.1 Laser. Gap control.
Gap control makes it possible to maintain a set distance between the laser nozzle and the
surface of the sheet. This distance is calculated by a sensor connected to the CNC, so that
it offsets the sensor variations on the distance programmed with additional movements in
the longitudinal axis.
The CNC allows only one gap control. When trying to activate the gap control from a channel
when it is already active in another channel, the CNC will issue the corresponding error
message.
The PLC can activate the gap control by executing the corresponding CNC block with the
CNCEX command. The instruction executed from the PLC updates the instruction
programmed from the CNC and vice-versa.
Sensor calibration.
For correct following by the sensor, it is recommended that the sensor signal be calibrated
with the maximum number of points possible.
Programming from the CNC.
The #GAPCTRL ON instruction may be used to activate the gap control. The #GAPCTRL
OFF instruction disables the gap control. The programming format is the following; the
arguments appear between curly brackets and the optional ones, between angle brackets.
Refer to the operating manual for more information.

For the gap control, the software option "GAP CONTROL" should be available.
The CNC does not allow work when the three functionalities are active simultaneously; leapfrog
(#LEAP), gap control (#GAPCTRL), and synchronous switching (#SWTOUT).
