2.10 Operation selection function parameters
2.10.1 Retry function (Pr. 66
When any protective function (major fault) is activated and the inverter stops its
output, the inverter itself resets automatically and performs retries. Whether
retry is performed or not, alarms reset for retry, number of retries made and
waiting time can be selected.
When you have selected automatic restart after instantaneous power failure
(with speed search), restart operation is performed at the retry operation time
which is the same of that of a power failure. (Refer to page 90 for automatic
restart function.)
