Punching and nibbling
12
12.1 Activation, deactivation
12.1.1 Punching and nibbling on or off (SPOF, SON, PON, SONS, PONS,
PDELAYON, PDELAYOF, PUNCHACC)
Function
Activate/deactivate punching and nibbling
PON and SON are used to activate the punching and nibble functions. SPOF terminates all
punching- and nibble-specific functions. Modal commands
PON and SON are mutually
exclusive, i.e.,
PONdeactivates SONand vice versa.
Punching/nibbling with leader
The functions
SONS and PONS also switch-in the punching or nibbling functions.
Unlike
SON/PON (stroke control at interpolation level), with these functions, signal-related
control of stroke initiation is at servo level. This enables higher stroke frequencies and, as a
result, increased punching capacity to be achieved.
While signals are being evaluated in the leader, all functions that cause the nibbling or
punching axes to change position (e.g. handwheel travel, changes to frames via PLC,
measurement functions) are inhibited.
Punching with delay
PDELAYON results in a delayed output of the punching stroke. The modally effective command
has a preparatory function and therefore is generally located before
PON. Normal punching
resumes after
PDELAYOF.
Note
The delay time is set in setting data SD42400 $SC_PUNCH_DWELLTIME.
Travel-dependent acceleration
PUNCHACC can be used to specify an acceleration characteristic defining different rates of
acceleration dependent on the hole spacing.
