Punching and nibbling with leader, PONS/SONS
The SONS and PONS commands also activate the
punching or nibbling functions.
In contrast to SON/PON – stroke control on
interpolation level – PONS and SONS control stroke
initiation on the basis of signals on servo level.
This means that you can work with higher stroke
frequencies and thus with an increased punching
capacity.
While signals are evaluated in the leader, all
functions that cause the nibbling or punching axes to
change position are inhibited.
Example: Handwheel mode, changes to frames via
PLC, measuring functions.
Otherwise PONS and SONS work in exactly the
same way as PON and SON.
Punching with delay
PDELAYON effects a delay in the output of the
punching stroke. The command is modal and has a
preparatory function. It is thus generally
programmed before PON.
Punching continues normally after PDELAYOF.
