Parameters
Retry count check (Pr. 69)
● Reading the Pr. 69 value provides the cumulative number of successful restart times made by
retries. The cumulative count in Pr. 69 increases by 1 when a retry is successful. Retry is regarded
as successful when normal operation continues without a fault for the Pr. 68 setting multiplied by
four or longer (3.1 s at the shortest). (When retry is successful, the cumulative number of retry
failures is cleared.)
● Writing "0" in Pr. 69 clears the cumulative count.

Selecting retry generating faults (Pr. 65)
Using Pr. 65, you can select the fault that will cause a retry. No retry will be made for the fault not in-
dicated. (For the fault details, refer to page 6-10.)
"  " indicates the faults selected for retry.
