Monitoring
Note!
Fault messages can only be reset, when the fault has been eliminated.
Change of the monitoring functions
Purpose
The changeover offers the possibility to select whether the monitoring function is
indicated as TRIP, warning, message with pulse inhibit or without pulse inhibit.
Furthermore, monitoring functions can also be switched off.
Warning!
For safety reasons the drive should always be disconnected from the mains while
trouble shooting mains failures or failures of the actual value encoder.
TRIP
In the event of a failure, the ignition pulses for armature circuit and field circuit are
inhibited, the digital outputs TRIP and IMP are set and RDY is reset. The failure is
automatically indicated under C067 and it is entered in the history buffer. The
history buffer is not deleted when switching off the mains.
A TRIP must be reset after the fault has been eliminated.
Warning
In the event of a failure one of the freely assignable digital outputs is set (if the
function "Warning" is assigned to the output). The warning is automatically
indicated under C066 and it is entered in the history buffer. The history buffer is not
deleted when switching off the mains.
A warning must be reset after the fault has been eliminated.
Stop!
If a controller protecting monitoring function ("I¼t monitoring", overtemperature
heat sink, overvoltage) is selected as warning, the controller can be destroyed if
the fault is not eliminated in time.
