Braking ramp monitoring (productive version)
When using the productive version of PSENvip braking ramp monitoring is absolutely es-
sential. To monitor the braking ramp the press overruns must be measured at various
speeds; i.e. an overrun profile must be created. The user has to determine a monitoring
curve (worst case curve) from the overrun profile. The determined monitoring curve is valid
generally and it can be adapted upwards if required, provided that safety is guaranteed.

.
Two procedures can be selected for brake ramp monitoring:
Brake ramp monitoring by the PAS4000 user program
In this procedure the current position has to be determined safely using two incremental en-
coders. The electronic modules PSSu E F INC and PSSu K F INC are available to record
and evaluate the current position values safely. Please refer to the operating manual of the
electronic module you are using.
It is the task of the PAS4000 user program to monitor the monitoring curve for any violation
using the safely determined current positions.
Braking ramp monitoring using PSENvip
From Hardware version 2 and Firmware version 2.0 the receiver PSENvip R/PSENvip R LR
is supported by a procedure for braking ramp monitoring. For braking ramp monitoring by
PSENvip, a special module PSSu K F FAU P from Hardware version 3 and Firmware ver-
sion 2.0
is required.
For braking ramp monitoring, the values of the monitoring curve (worst case curve) have to
be transferred via the PAS4000 user program to the special module PSSu K F FAU P.
Please refer to the PSSu K F FAU operating manual for this information.
The special module PSSu K F FAU P uses the current position values coming from the
PSENvip to monitor the monitoring curve for violation.
