8.14 Special functions for laser cutting machines
You can activate special functions to interface the iTNC to laser cutting
machines and water jet machines.
8.14.1 Analog voltage output
If you do not need the analog output S of the CMA-H for the spindle, you can
define other functions for this output:
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)
Voltage
proportional to the
contouring feed
rate, MP3011 = 1
A voltage proportional to the current contouring feed rate is output:
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]
Voltage from the
PLC, MP3011 = 2
The voltage that you have defined with Module 9130 is output.
Definition of the
voltage through
M functions,
MP3011 = 3
The voltage to be output is defined through M functions M200 to M204:
Set MP3011 = 3, otherwise the M functions described above are not
available.
The M functions are executed synchronously to the positioning blocks and are
effective at the beginning of the positioning blocks.
Direct output of the
programmed
voltage: M200 V...
The iTNC 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.
Voltage output
varies with the
distance: M201 V...
The iTNC outputs the voltage as a function of the traversed distance. Starting
from the active voltage, the iTNC 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.
