8. 3 Indication in trip status
When the inverter trips, details of the trip status are indicated. In the status monitor mode, the
status when the inverter trips is held.

Note: Past trip indications (that have been saved in the memory or that appeared in the past)
can be read out. (Refer to "Status monitor mode, 8.1".)
(*1)This is not a trip indication, but it appears when no error record is found in monitoring the
past trip indications.
