TE8: Cycle-independent path-synchronous switching
signal output - 840D sl only
20.1

Brief description

Function
The "Cycle-independent path synchronized switching signal output" technological function
serves the purpose of switching time-critical, position-based machining processes on and off
quickly, e.g. high speed laser cutting (HSLC; High Speed Laser Cutting).
The switching signal output can be block-related or path length-related:
● Block-related switching signal output
The switching signal output and therefore, the activation / deactivation of the machining is
undertaken independently of the status changes:
– Rapid travel mode G00 active / inactive
– Programmed feed threshold fell short / exceeded
● Path length-related switching signal output
The switching signal output and therefore, the activation / deactivation of the machining
takes place in a continuous change and is monitored along the traversed path.
This enables a regular machining without the individual switching positions having to be
programmed explicitly.
The activation or selection of the mentioned options leads to the monitoring of the output of
the digital signal which is programmed with a part program command.
I/Os
Only the on-board I/Os of the NC module can be used as the digital I/O via which the switching
signal is output: The switching signal can only be output via one of the 4 on-board digital outputs
on the NCU module.
Restrictions
The use of the "Cycle-independent path synchronized switching signal output" technological
function is subject to the following restriction:
● The technological function is available only in one channel of NC.
References
The "cycle-independent path-synchronous switching signal output" technological function is a
compile cycle. For the handling of compile cycles, see Section "TE01: Installation and
activation of loadable compile cycles (Page 549)".
