10.4.5 Delete distance-to-go (DELDTG)
Function
Delete distance-to-go can be triggered for a path and for specified axes depending on a
condition.
The possibilities are:
● Fast, prepared delete distance-to-go
● Unprepared delete distance-to-go
Prepared delete distance-to-go with DELDTG permits a fast response to the triggering event
and is therefore used for time-critical applications, e.g. if
● the time between delete distance-to-go and the start of the next block must be very short.
● the condition for delete distance-to-go will very probably be fulfilled.
Note
The axis designation contained in brackets behind DELDTG is only valid for one
positioning axis.
