Example of fast axial deletion of distance-to-go
Program code Comments
Cancelation of a positioning movement:
ID=1 WHEN $A_IN[1]==1 DO MOV[V]=3 FA[V]=700 ; Start axis
WHEN $A_IN[2]==1 DO DELDTG(V) ; Delete distance-to-go, the axis
is stopped using MOV=0
Delete distance-to-go depending on the input
voltage:
WHEN $A_INA[5]>8000 DO DELDTG(X1) ; As s
o
on as the voltage at input 5
exceeds 8V, delete distance-to-
g
o
for axis X1.
Path motion continues.
POS[X1]=100 FA[X1]=10 G1 Z100 F1000
Further Information
At the end of a traversing block in which a prepared delete distance-to-go was triggered,
preprocess stop is activated implicitly.
Continuous path mode or positioning axis movements are therefore interrupted or stopped at
the end of the block with fast delete distance-to-go.
Note
Prepared delete distance-to-go:
• cannot be used with active tool radius correction.
• the action must only be programmed in non modal synchronized actions (without ID
number).
