18.3 Checking Error Information
18.3.1 Checking trip information
• The inverter generated an error and tripped. You
want to see the information of the moment the error
occurred.
• Up to 10 trips in the past is displayed as the trip
history.
• The latest trip history is displayed on the trip
monitor 1.
• The following data items are displayed on the
monitor:
1) Error factor for trip
2) Output frequency (Hz) at trip
3) Output current (A) at trip
4) Main circuit DC voltage (V) at trip
5) Operation state at trip
6) Cumulative inverter operating time (h) before trip
7) Cumulative inverter power-on time (h) before trip

“Detailed monitor” for checking the history
• You can look through the history
with the arrow keys.
• The information of the moment of error occurrence
may not be fetched properly if the inverter is
forcibly turned OFF by its hardware.
• Values of respective data items may be reset to 0
when an error occurred and the inverter entered
the trip condition.
• For a ground fault or a momentary overcurrent
event, the current may be recorded in a value lower
than the actual value.
• The trip monitor and the trip count monitor can be
cleared by initialization of the trip history.
