12-1 Checking Alarm Display
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:
(a) Error factor for trip
(b) Output frequency (Hz) at trip
(c) Output current (A) at trip
(d) Main circuit DC voltage (V) at trip
(e) Operation state at trip
(f) Cumulative inverter operating time (h) before trip
(g) Cumulative inverter power-on time (h) before trip
Precautions for Correct Use
• 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.
