Dynamic muting (productive version)
Dynamic muting is a procedure in which the protected field is gradually reduced by deactiv-
ating defined segments. The gradual reduction begins when the protected field meets the
workpiece.
Dynamic muting is only possible with the productive version.
To safeguard dynamic muting, the following safety functions must be implemented in the
user program:
Monitoring of the pinch point
}
Monitoring the press braking ramp
}
The following procedures are possible:
– Brake ramp monitoring by the PAS4000 user program
– Braking ramp monitoring using PSENvip
Definition of the safe position and safe speed of the upper tool.
}
Certified blocks are available in the PAS4000 Library for this purpose (see online help for
PAS4000).
An advance measuring field is located below the protected field. Dynamic muting is started
as soon as the advance measuring field touches the workpiece. Dynamic muting ensures
that, during the downward movement of the press, the danger zone between upper tool and
workpiece is monitored until the muting end point is reached (see
ductive version) [
The distance of the advance measuring field to the lower edge of the protected field is con-
stant. The distance to the top edge of the protected field varies according to the length of
the overrun.

INFORMATION
If the workpiece is thinner than 1 mm, it will not be detected by the advance
measurement beam.
Remedy: Attach a magnetic metal sheet to the lower tool (covering the die
V-groove).
