After deletion of the distance-to-go, the value of the deleted distance-to-go can be read via a
system variable:
● Path distance-to-go: $AC_DELT
● Axial distance-to-go: $AA_DELT
Syntax
DELDTG
DELDTG(<axis 1>[,<axis 2>, ... ])
Meaning
Parameter
DELDTG
DELDTG(...)
<Axis n>:
Supplementary conditions
Path-specific and axial delete distance-to-go
Path-specific and axial delete distance-to-go can only be executed in a non-modal
synchronized action (without specification of ID or IDS).
Path-specific delete distance-to-go
● The deletion of the path distance-to-go can only be executed in a non-modal synchronized
action (without specification of ID or IDS).
● The deletion of the path distance-to-go must not be used with active tool radius
compensation.
Axial delete distance-to-go
Delete distance-to-go for indexing axes:
● Without Hirth tooth system: The axis is braked immediately
● With Hirth tooth system: The axis traverses to the next indexing position
Examples
Delete path distance-to-go
If the input $A_IN is set during the traversing block N20, the path distance-to-go is deleted.
