4.2.20 Retry function (Pr. 65, Pr. 67 to Pr. 69)
Pr. 65 "retry selection"
Pr. 67 "number of retries at alarm occurrence"
Pr. 68 "retry waiting time"
Pr. 69 "retry count display erasure"
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.
