Punching and nibbling
12.1 Activation, deactivation
Travel-dependent acceleration
PUNCHACC can be used to specify an acceleration characteristic defining different rates of
acceleration dependent on the hole spacing.
Second punching interface
Machines which need to use a second punching interface (second punching unit or
comparable medium) alternately can be switched over to a second pair of fast digital inputs
and outputs on the control (I/O pair). Full punching/nibbling functionality is available on both
interfaces. The SPIF1 and SPIF2 commands are used to switch over between the first and
second punching interface.
Note
Condition: A second I/O pair has to be defined for the punching functionality in the machine
data (→ see machine manufacturer's specifications).
