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.
