Function
Functions that have been activated are visible in the program control
display (can be set via "Program control", see Subsection 4.6.12). The
functions are displayed irrespective of the selected menu.
Program blocks in which the block no. is preceded by a slash are
skipped when you run the program (e.g. "/N100 ...").
From SW 6.4 you can hide up to 10 program levels (e.g. "/6N100 ..";
the 7th program level is hidden)

n = active skip levels
If this function is active, execution is interrupted after every block that
triggers a function on the machine
(calculation blocks do not cause an interruption).
If this function is active, the part program blocks are executed as
follows: Each block is decoded separately and execution is interrupted
after every block.
If this function is active, the part program blocks are executed
individually in the cycle as follows:
Each block is decoded separately and execution is interrupted after
every block. Part program blocks are
• Traversing blocks
• Switching and auxiliary functions
• Blocks generated within the control
(e.g.: blocks inserted by tool radius compensation)
• Thread blocks after retraction
• Thread blocks with dry run feedrate
Thread blocks without dry run feedrate are an exception to this. Here,
execution is only interrupted at the end of the current thread block.
SBL2 can only be selected in the Reset state.
Either SBL1 or SBL2 can be selected!
This function can be activated only in the "Single block" state.
Traverse movements are performed with the feedrate value set in the
setting data "Dry run feedrate".
This dry run feedrate function replaces the programmed motion
commands.
