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 important performance data at the moment of the fault. To access the data,
use the monitor function (xxx) and select
faults are stored in
error to .
The following Monitor Menu map shows how to access the error codes. When fault(s) exist,
you can review their details by first selecting the proper function:

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.
