5.2 Display of trip information
5.2.1 Trip code display
If the inverter trips, an error code is displayed to suggest the cause. Since trip records are retained, information
on each trip can be displayed anytime in the status monitor mode.
For the kinds of causes that can be indicated in the event of a trip, see section 9.1.
5.2.2 Display of trip information at the occurrence of a trip
At the occurrence of a trip, the same information as that displayed in the mode described in 5.1.1, "Status monitor
under normal conditions," can be displayed, as shown in the table below, if the inverter is not turned off or reset.
To display trip information after turning off or resetting the inverter, follow the steps described in 5.1.2, "Display of
detailed information on a past trip."
