17 Special functions for laser cutting machines

Special functions can be activated to interface the TNC to laser cutting machines and water jet
machines.

17.1 Analogue voltage output

If the analogue output (X8, pin 8) is not needed for the spindle, MP3011 can define another function
for this analogue output. The input values in MP3011 show an effect only if the value in MP3010 is
less than 3.
MP3011 Function of analogue output S, if MP3010 < 3
Entry: 0 to 3
0 = No special function
1 = Voltage proportional to current contour feed rate (depending on MP3012)
2 = Voltage as defined by PLC module 9130
3 = Voltage is defined via M function (M200 to M204)
17.1.1 Voltage proportional to feed rate (MP3011 = 1)
A voltage proportional to the current contour feed rate is output. The feed rate achieved when 10 V is
output is entered in MP3012.
MP3012 Feed rate for output of an analogue voltage of 10 V (MP3011 = 1)
Entry: 0 to 300 000 [
17.1.2 Voltage from the PLC (MP3011 = 2)
The voltage defined through the PLC module 9130 is output. See also chapter "PLC Programming".
17.1.3 Definition of the voltage via M function (MP3011 = 3)
The analogue voltage output can be defined in the positioning block with the miscellaneous functions
M200 to M204. These M functions are available only if the value 3 is entered in MP3011. The M
functions are executed synchronously to the positioning blocks and are effective at the beginning of
the block.
