S Parameters Pr.9 and Pr.10 only operate
when Pr.8 is set to 1(Yes).
The number of attempts to try the auto
restart is set at Pr.9.
If a fault trip occurs during operation, the
drive automatically restarts after the set time
programmed at Pr.10.
At each restart, the drive counts the number
of tries and subtracts it from the number set
at Pr.9 until the retry number count reaches
0. After an auto restart, if a fault trip does not
occur within 60 secs, it will increase the
restart count number. The maximum count
number is limited by Pr.10.
