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 functions (Dxxx) and select D081 for details about the
present fault (En). The previous two faults are stored in D082 and D083, with D(En-1
and En-2). Each error shifts D081–D082 to D082–D083, and writes the new error to
D081.
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: D081 is the
most recent, and D083 is the oldest.
