Punching and Nibbling (N4)
Activation and deactivation
SONS
Nibbling ON (in position control cycle)
SONS behaves in the same way as SON. The function is activated in the position control
cycle, thus allowing time-optimized stroke initiation and an increase in the punching rate per
minute.
PON
Punching ON
PON activates the punching function and deactivates SON.
PON has a modal action like SON.
In contrast to SON, however, a stroke is not executed until the end of the block or, in the case
of automatic path segmentation, at the end of a path segment. PON has an identical action
to SON in the case of blocks which contain no traversing information.
Programming example:
:
:
N100 Y30 SPOF
N110 Y100 PON

PONS
Punching ON (in position control cycle)
PONS behaves in the same way as PON. For explanation, please refer to SONS.
PDELAYON
Punching with delay ON
PDELAYON is a preparatory function. This means that PDELAYON is generally programmed
before PON. The punch stroke is output with a delay when the programmed end position is
reached.
The delay time in seconds is programmed in setting data:
SD42400 $SC_PUNCH_DWELLTIME
If the defined value cannot be divided as an integer into the interpolation clock cycle, then it
is rounded to the next divisible integer value.
The function has a modal action.
