8 Subprograms and Program Section Repeats
TNC 124 97
Program section repeats
A program section repeat is entered like a subprogram. The end of
the program section is identified simply by the command to repeat
the section.
Label 0 is therefore not set.
Display of the CALL LBL block with a program section repeat
The screen displays (for example): CALL LBL 1 REP 10 / 10 .
The two numbers with the slash between them indicate that this is a
program section repeat. The number in front of the slash is the
number of repeats you entered. The number behind the slash is the
number of repeats remaining to be performed.
Programming example: Program section repeat for slots

Slot depths: – 12 mm
Incremental offset
of the infeed point : 15 mm
