7.6 Miscellaneous Functions for
Laser Cutting Machines
Principle
The TNC can control the cutting efficiency of a laser by transferring
voltage values through the S-analog output. You can influence laser
efficiency during program run through the miscellaneous functions
M200 to M204.
Entering miscellaneous functions for laser cutting machines
If you enter an M function for laser cutting machines in a positioning
block, the TNC continues the dialog by asking you the required
parameters for the programmed function.
All miscellaneous functions for laser cutting machines become
effective at the start of the block.
Output the programmed voltage directly: M200
Behavior with M200
The TNC outputs the value programmed after M200 as the voltage V.
Input range: 0 to 9 999 V
Effect
M200 remains in effect until a new voltage is output through M200,
M201, M202, M203 or M204.
Output voltage as a function of distance: M201
Behavior with M201
M201 outputs the voltage in dependence on the distance to be
covered. The TNC increases or decreases the current voltage linearly
to the value programmed for V.
Input range: 0 to 9 999 V
Effect
M201 remains in effect until a new voltage is output through M200,
M201, M202, M203 or M204.
Output voltage as a function of speed: M202
Behavior with M202
The TNC outputs the voltage as a function of speed. In the machine
parameters, the machine tool builder defines up to three characteristic
curves FNR in which specific feed rates are assigned to specific
voltages. Use miscellaneous function M202 to select the curve FNR
from which the TNC is to determine the output voltage.
Input range: 1 to 3
