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 (dxxx) and select
previous 5 faults are stored in
d081-d085 to d082-d086, and the latest error log is written in d081.
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:
D086
and is the oldest.

Note: 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.
