Trip History And Inverter Status - Hitachi WJ200 Series Instruction Manual

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 (dxxx) and select
present fault. The previous 5 faults are stored in
to d082-d086, and writes the new error to d081.
d081-d085
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.
