RIDE-THROUGH RESTART (Parameter P49)

CAUTION

:

●

Depending on the ride-through restart function settings, the motor may restart suddenly

after the power is restored.
(Ensure personal safety before restarting.)
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.

•

"LU" will be displayed, and a fault warning signal will be output.

Operation

continues

•

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.

Operation takes place
according to the details
set in the start mode.

Note 1)

This is the min. time for operation at the rated output current.

(This time may be longer depending on the model.)

Note 2)

This is the min. time. (This time may be longer if the rated capacity is larger.)

Even if the power failure time is relatively long (approx. 1 min.), the inverter may
restart after the power is restored. Wait at least four min. (wait time + 2 min.) after
the power is restored before handling the inverter, motor or load facility.

Note 3)

The wait time can be set between 0.1 to 100 sec. with parameter P50.

[When voltage drop time is more than 15ms but less than 100ms.]
