●
The path segments are rounded off by the control system if required so that a total
programmed distance can be divided into an integral number of path sections.
●
The path segment unit is either mm/stroke or inch/stroke (depending on axis settings).
●
If the programmed
SPP
value is greater than the traversing distance, then the axis is
positioned on the programmed end position without path segmentation.
●
SPP = 0
, reset or program end delete the programmed
SPP
value. The
SPP
value is not
deleted when punching/nibbling is deactivated.
SPN
The automatic path segmentation function
SPN
divides the traversing path into the
programmed number of path segments.
The following conditions apply:
●
Path segmentation is active only when
SON
or
PON
is active.
(Exception: MD26014 PUNCH_PATH_SPLITTING = 1)
●
SPN
has a non-modal action.
●
Any previously programmed
SPP
value is suppressed for the block containing SPN, but is
re-activated again in the following blocks.
Supplementary conditions
●
The path segmentation function is operative with linear and circular interpolation.
The interpolation mode remains unchanged, i.e. circles are traversed when circular
interpolation is selected.
●
If a block contains both
SPN
(number of strokes) and
SPP
(stroke path), then the number of
blocks is activated in the current block while the stroke path is activated in all blocks that
follow.
●
Path segmentation is active only in conjunction with punching or nibbling functions.
(Exception: MD26014 PUNCH_PATH_SPLITTING = 1).
●
Any programmed auxiliary functions are output before, during the first or after the last
sub-block.
●
In the case of blocks without traversing information, the rules which govern the
programming of
SON
and
PON
also apply to
SPP
and
SPN
. In other words, a stroke is initiated
only if an axis motion has been programmed.
