Ride-Through Restart (Parameter P24); When Voltage Drop Time Is More Than 15Ms But Less Than 100Ms - Panasonic AAD03011 Instruction Manual

RIDE-THROUGH RESTART(Parameter P24)
! Caution
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.

The LU trips, and the inverter operates according to the start
mode setting.
"LU" will be displayed, and a fault warning signal will be output.
Restart from 0Hz after the wait time has elapsed.
"LU" will be displayed, but a fault warning signal
will not be output.
After the wait time has elapsed, the inverter restarts
at the frequency applied before the ride-through
restart occurred.
"LU" will be displayed, but a fault warning signal
will not be output.
