List of warnings and alarms

The table gives the different warnings and alarmsand
indicates whether the fault locks the frequency
converter. After Trip locked, mains supply must be cut
and the fault must be corrected. Reconnect mains
supply and reset the frequency converter before being
ready. A Trip can be reset manually in three ways
1. Via the control key [RESET]
2. Via a digital input
3. Via serial communication
In addition, an automatic reset may be selected
in parameter 400 Reset function.
No.

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 117 Motor
thermal protection. After a trip, the motor will be
coasting and on the frequency converter alarm and
warning will flash. If the fault is removed, only the
alarm will flash. After a reset, the frequency converter
will be ready to start operation again.
