Monitoring Trip Events, History, & Conditions
Trip History and Inverter Status
We recommend that you first find the cause of the fault before clearing it. When a fault occurs,
the inverter stores the important performance data at the moment of the fault. To access the
data, use the monitor function (
xxx) and select
details about the present fault. The
previous 5 faults are stored in
to
. When a fault occurs, each error log shifts
-
to
-
, and the latest error log is written in
.
The following Monitor Menu map shows how to access the error logs. When fault(s) exist,
you can review their details by first selecting the proper function:
is the most recent,
and
is the oldest.

ote: Indicated inverter status could be
different from actual inverter behavior.
e.g. When PID operation or frequency given
by analog signal, although it seems constant
speed, acceleration and deceleration could
be repeated in very short cycle.
