Call work offsets

You can call work offsets (G54, etc.) from any program.
You define work offsets in work offset lists. You can also view the coordinates of the selected
offset here.
Procedure
7.10

Repeating program blocks

If certain steps when machining a workpiece have to be executed more than once, it is only
necessary to program these steps once. You have the option of repeating program blocks.
Start and end marker
You must mark the program blocks that you want to repeat with a start and end marker. You
can then call these program blocks up to 9999 times within a program. The markers must be
unique, i.e. they must have different names. No names used in the NCK can be used.
You can also set markers and repeats after creating the program, but not within linked
program blocks.
Note
You can use one and the same marker as end marker for preceding program blocks and as
start marker for following program blocks.
