7.6 Miscellaneous Functions for Laser Cutting Machines
7.6 Miscellaneous Functions for Laser
Cutting Machines
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 block.
Output the programmed voltage directly: 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
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
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
Effect
M202 remains in effect until a new voltage is output through M200,
M201, M202, M203 or M204.
Output voltage as a function of time
(time-dependent ramp): M203
The TNC outputs the voltage V as a function of the
time TIME. The TNC increases or decreases the
current voltage linearly to the value programmed for
V within the time programmed for TIME.
Input range
Voltage V: 0 to 9.999 Volt
TIME: 0 to 1.999 seconds
Effect
M203 remains in effect until a new voltage is output
through M200, M201, M202, M203 or M204.
Output voltage as a function of time
(time-dependent pulse): M204
The TNC outputs a programmed voltage as a pulse
with a programmed duration TIME.
Input range
Voltage V: 0 to 9.999 Volt
TIME: 0 to 1.999 seconds
Effect
M204 remains in effect until a new voltage is output
through M200, M201, M202, M203 or M204.
