When inverter operation stops due to a fault and a fault trip is activated, the inverter
automatically restarts based on the parameter settings.

Description
Pr.08 RST
Restart, Pr.09
Retry Number,
Pr.10 Retry
Delay
Only operates when Pr.08 (RST Restart) is set to 1 (Yes). The
number of attempts to try the auto restart is set at Pr.09 (Auto Restart
Count). If a fault trip occurs during operation, the inverter
automatically restarts after the set time programmed at Pr.10 (Retry
Delay). At each restart, the inverter counts the number of tries and
subtracts it from the number set. Once the retry number count
reaches 0, the automatic restart is not conducted. After an auto
restart, if a fault trip does not occur within 60 sec, it will increase the
restart count number. The maximum number of increase is limited by
the number set for Auto Restart Count.
If the inverter stops due to low voltage, emergency stop (Bx), inverter
overheating, or hardware diagnosis, an auto restart is not activated.
At auto restart, the acceleration options are identical to those of
speed search operation. Codes Cn.72–75 can be set based on the
load. Information about the speed search function can be found at
5.13 Speed Search Operation on page 145.
