Function Description
Funktion_Schutzfeld_Basis
The protected field can be overridden (muted) when a closing speed of
≤
10 mm/s is achieved. Muting is a function of the programmable safety
system.
The press brake must provide a signal to indicate that a closing speed
of
≤
10 mm/s has been achieved (creep speed mode). The programmable
safety system (e.g. PSS, PNOZmulti) must receive this signal for creep
speed mode before the protected field meets the workpiece.
Funktion_Schutzfeld_Hinweise
The two following sections explain the basic mode of action of the pro-
tected field during a press stroke (interrupted and uninterrupted).
INFORMATION
Please note that the central segments are 1 mm behind the
bending line. With box bending you must ensure that the side
panels of the box do not encroach into this area.
INFORMATION
The cycle of a press stroke with the corresponding inputs and
outputs is explained in this chapter, in the section entitled "Sys-
tem cycle".
