RIDE-THROUGH RESTART(Parameter P24)
Depending on the restart setting after an instantaneous power failure, the
inverter may automatically start(restart) if the power is restored after a power
failure. Keep out of the machine.
(Operate the inverter after ensuring personal safety. Failure to do so could
lead to injury.)
Used to select the restart mode after an instantaneous power failure occurs,
according to the load conditions and system. A wait timer function is built-in.
