17 Special functions for laser cutting machines
Direct output of the programmed voltage: M200 V...
The TNC outputs the value programmed behind M200 V... as a voltage.
Entry:
0 to 9.999 [V]
Duration:
M200 V... is effective until a new voltage is output through M200 to M204.
Voltage varies with distance: M201 V...
The TNC outputs the voltage as a function of the traversed distance. The TNC increases or decreases
the voltage linearly from the active voltage to the value programmed behind M201 V...
Entry:
0 to 9.999 [V]
Duration:
M201 V... is effective unit a new voltage is output through M200 to M204.
Voltage varies with the velocity: M202 FNR.
The TNC outputs the voltage as a function of the velocity. With machine parameters MP3013.x and
MP3014.x up to 3 characteristic curves are defined in a table. In the table certain analogue voltages
are assigned to certain feed rates. M202 FNR. selects the characteristic curve in which the TNC finds
the voltage to be output.
Entry:
1 to 3
Duration:
M202 FNR. is effective until a new voltage is output through M200 to M204.
You can enter in the table up to four kink points per characteristic curve. The output values are
interpolated linearly between the kink points. The first kink point must have the value 0. The entry
values of the following kink points must increase in sequence. The TNC recognizes the beginning of a
new characteristic curve from the entry value 0.
