Path Length-Related Switching Signal Output - Siemens SINUMERIK 840D sl Function Manual

• Position X30 for edge change from N10 to N20
• Position X70 for edge change from N20 to N30
Note
G0 always deactivates the switching signal, regardless of the threshold value.

Path length-related switching signal output

Programmable paths as the switching criterion
In path-related switching signal output, the switching positions are defined with the help of the
two freely programmable paths s
Functional sequence
The path length-related switching signal output starts with a switch on signal at the beginning
of the first traversing block after activation with CC_FAST_CONT (refer to
The processing is active till a deactivation signal is set after the traversing of a programmable
path s
set again after the traversing of a programmable path s
The changeover between activation and deactivation signal, and therefore between
processing and interruption phase is path length dependent at the end of either of the stretch
sections s
switching positions having to be programmed explicitly.
The path length-related switching signal output ends with the start of the first traversing block
(or of another executable block) after deactivation with CC_FASTOFF (refer to
