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 (D_xx) and select D_08 for details about the
present fault (E
n
), or the error code for the past two trip events (E
n-1
and E
n-2
) using the
D_09 Trip History function.
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: D_08 displays
current trip data, and D_09 displays trip history.
