12.1.1 Punching and nibbling On or Off (SPOF, SON, PON, SONS, PONS,
PDELAYON/OF)
Function
Punching and nibbling activate, deactivate, PON/SON
The punching and nibbling functions are activated with PON and SON respectively. SPOF
terminates all functions specific to punching and nibbling operations. Modal commands PON
and SON are mutually exclusive, i.e., PON deactivates SON and vice versa.
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.
Punching with delay, PDELAYON/PDELAYOF
PDELAYON brings about 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.
