.10 Operation Selection Function Parameters

.10.1 Retry function

When any protective function (major fault) is activated and the inverter stops its

output, the inverter itself resets automatically and performs retries. You can

select whether retry is made or not, alarms reset for retry, number of retries

made, and waiting time.

made by retry. The setting of "0" erases the cumulative number of times.
