6.22 Special Functions for Laser Cutting Machines
6.22.1 Analog Voltage Output
Voltage
proportional to the
contouring feed
rate, MP3011 = 1
Voltage from the
PLC, MP3011 = 2
Definition of the
voltage through
M functions,
MP3011 = 3
Direct output of the
programmed
voltage: M200 V...
Voltage output
varies with the
distance: M201 V...
6 – 452
You can activate special functions to interface the TNC to laser cutting
machines and water jet machines.
If you do not need the analog output S (X8, pin 8) for the spindle, you can
define other functions for this output:
7 7 7 7
With MP3011, select the function of analog output S. If MP3010 > 3,
MP3011 has no effect.
MP3011
Function of analog output S, if MP3010 < 3
Input:
0: No special function
1: Voltage is proportional to the current contouring feed rate,
depending on MP3012
2: Voltage is defined as through Module 9130
3: Voltage is defined through M functions (M200 to M204)
A voltage proportional to the current contouring feed rate is output:
7 7 7 7
In MP3012, enter the feed rate achieved when a 10-V analog voltage is
output.
MP3012
Feed rate from output of an analog voltage of 10 V,
MP3011 = 1
Input:
0 to 300 000 [mm/min]
The voltage that you have defined with Module 9130 is output.
The voltage to be output is defined through M functions M200 to M204:
7 7 7 7
Set MP3011 = 3,
otherwise the above-mentioned M functions will not be available.
The M functions are executed synchronously to the positioning blocks and are
effective at the beginning of the positioning blocks.
The TNC outputs the value after M200 V... as a voltage.
Input: 0 to 9.999 [V] Duration of effect: M200 V... is effective until a new
voltage is output with M200 to M204.
The TNC outputs the voltage as a function of the traversed distance. Starting
from the active voltage, the TNC increases or decreases the voltage linearly to
the value programmed behind M201 V.
Input: 0 to 9.999 [V]
Duration of effect: M200 V... is effective until a new voltage is output with
M200 to M204.
