8.2 Display of trip information
If the inverter trips, an error code is displayed to suggest the cause. In the status monitor mode, all
trip records are retained.

(Note) Past trip records (trip records retained or trips that occurred in the past) can be called up.
(Refer to 8.1 "Status monitor mode" for the call-up procedure.)
(*) Strictly speaking, this code is not an error code; this code is displayed to show the
absence of error when the past trip monitor mode is selected.
