â– Warnings and alarms
The table gives the different warnings and alarms
and indicates whether the fault locks the frequency
converter. After Trip locked , the mains supply
must be cut and the fault must be corrected.
Reconnect the mains supply and reset the frequency
converter before being ready.
Wherever a cross is placed under both Warning
and Alarm, this can mean that a warning precedes
the alarm. It can also mean that it is possible to
program whether a given fault is to result in a warning
or an alarm. This is possible, e.g. in parameter
404 Brake check. After a trip, alarm and warning
will flash, but if the fault is removed, only alarm
will flash. After a reset, the frequency converter
will be ready to start operation again.
