4.9.2
System cycle for box bending press stroke
PSENvip transfers position values to the special module PSSu K F FAU P (see I/O data
type PROTECTION_FIELD_SIZE), which can be used in the user program for feasibility
testing.
Please note:
}
On each press stroke, the "Reduced protected field" protected field mode
must
be star-
ted via an acknowledgement. The acknowledgement can take place either when the
press stroke is started at top dead centre or after the protected field meets the workpiece
(see
Protected field modes [
23]
).
}
In box bending protected field mode, the front segments of the protected field are
blanked.
