If the programmed path segmentation is not an integral multiple of the total path, then the
feed path is reduced.

Example of SPN
The number of path segments per block is programmed via
SPN
.
A value programmed via
SPN
takes effect on a non-modal basis for both punching and
nibbling applications. The only difference between the two modes is with respect to the first
stroke. This is normally executed at the beginning of the first segment with nibbling
operations and at its end with punching operations. This means that when n segments are
programmed, n strokes are executed with punching operations but n+1 with nibbling.
Furthermore, where no traversing information is available, only a single stroke is executed,
even if several are programmed. Should it be necessary to generate several strokes at one
position, then the corresponding number of blocks without traversing information must be
programmed.

Activate nibbling. The total path is divided into
three segments. A stroke is initiated before the
first movement and at the end of each segment.
