<Setting>
•Use Pr. 66 to select the protective functions (major faults) to be activated for
retries.No retry will be made for the alarm not indicated.(Refer to page 168)
* Indicates the retry items selected. (OCT denotes any of OC1 to OC3 and OVT
any of OV1 to OV3.)
•Use Pr. 67 to set the number of retries at alarm occurrence.
* If the retry count is exceeded, " " (retry count over) is displayed.
•Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a restart in
the range 0.1 to 360s.
•Reading the Pr. 69 value provides the cumulative number of successful restart times
made by retry. The cumulative number of time is cleared when setting value "0" is
written.
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 for retry, number of retries made and waiting
time can be selected.
