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.
