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.
Programming
Delete distance-to-go for the path
DO DELDTG
or
axial delete distance-to-go
DO DELDTG(axis1, axis2, ...)
Example of fast deletion of distance-to-go path
WHEN $A_IN[1]==1 DO DELDTG
N100 G01 X100 Y100 F1000
N110 G01 X...
IF $AA_DELT>50...
10-28
Note
The axis designation contained in brackets behind DELDTG is only valid for one
positioning axis.
; When the input is set, the movement is canceled
