Activating The Path Length-Related Switching Signal Output (Cc_Faston_Cont) - Siemens SINUMERIK 840D sl Function Manual

Programming example
Programming
DEF REAL DIFFON= -0.08
DEF REAL DIFFOFF= 0.08
DEF REAL FEEDTOSWITCH= 20000
CC_FASTON(DIFFON,DIFFOFF,FEEDTOSWITCH)
Changing parameters
The parameters for the CC_FASTON() procedure can be modified at any time during the
execution of the part program. To do this, enter the procedure call again with the new parameter
values. The switching criterion (G0 edge change / velocity threshold value) may also be
changed.
Reset response
A reset (NC RESET or end of program) deactivates the function.

Activating the path length-related switching signal output (CC_FASTON_CONT)

Syntax
CC_FASTON_CONT (PATH_DISTANCE_ON, PATH_DISTANCE_OFF)
CC_FASTON_CONT() is a procedure call and must therefore be programmed in a dedicated
part program block.
Parameter
The parameters for the CC_FASTON_CONT() procedure have the following meaning:
Parameter
< PATH_DISTANCE_ON >
< PATH_DISTANCE_OFF>
* The basic unit (inch or mm) depends on the current dimensions programming (G70 / G71 / G700 /
G710).
