WHEN $AC_DTEB<5 DO STOPREOF
G01 X100
IF $A_INA[7]>5000 GOTOF Label 1
If the distance to the end of the block is less than 5 mm, end preprocessing stop. If the
voltage at input 7 drops below 5V, jump forwards to label 1 (assuming that the value 1000
corresponds to 1 V).

DELDTG

Deletion of distance-to-go
Synchronized actions can be used to activate deletion of distance-to-go for the path and for
specified axes as a function of a condition.
• High-speed prepared deletion of distance-to-go
High-speed, prepared DDTG
High-speed/prepared deletion of distance-to-go is used in time-critical applications:
• if the time between deletion of distance-to-go and start of next block needs to be very
• if there is a high probability that deletion of distance-to-go will be activated.
DELDTG
Deletion of distance-to-go is programmed with synchronized action DELDTG.
After the distance-to-go has been deleted, the remaining path distance is stored in the
system variable $AC_DELT. Continuous-path mode is thus interrupted at the end of the
block with high-speed deletion of distance-to-go.
Constraints:
Deletion of distance-to-go for the path may only be programmed as a non-modal
synchronized action.
If tool radius compensation is active, fast deletion of distance-to-go cannot be used.
Commands:
MOVE=1:Works on indexing axes with and without Hirth tooth system MOV=0: Same function
for both: approaches the next position. Command: DELDTG: In the case of indexing axes
without Hirth tooth system: Axis stops immediately. In the case of indexing axes with Hirth
tooth system: Axis traverses to next position.
