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

TE8: Cycle-independent path-synchronous switching signal output
16.4 Programming
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.
16.4.2

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).
Programming example
Programming
DEF REAL PATH_DISTANCE_ON = 0.5
DEF REAL PATH_DISTANCE_OFF = 1.0
CC_FASTON_CONT (PATH_DISTANCE_ON, PATH_DISTANCE_OFF)
Changing parameters
The parameters for the CC_FASTON_CONT( ) procedure can be modified at any time during
the execution of the part program. For this, the procedure call must be specified again with
the new parameter values.
