Warnings and alarms
The table gives the different warnings and alarms and
indicates whether the fault locks the adjustable fre-
quency drive. After Trip locked, the mains supply must
be cut and the fault must be corrected. Reconnect the
mains supply and reset the adjustable frequency drive
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 warn-
ing 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 adjustable frequency drive will be ready to
start operation again.
