Trip History and Inverter Status

We recommend that you first find the cause of the fault before attempting 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 five faults are stored in D081 to D086, with D (En-1to En-5). Each error shifts D081–D085 to D082–D086, 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 most recent, and D086 is the oldest.
