(Note 1) This is the minimum time for operation at the rated output current.
(The time may be longer depending on different models.)
(Note 2) This is the minimum time. (The time may be longer with higher

The inverter may suddenly start (restart) if the power is
restored after a power failure with the setting of
ride-through restart, so do not approach the unit.
(Please take measures to ensure personal safety.)
Failure to do so may result in injury.

·LU trip occurs and the inverter operates according to the start
mode setting.
·"LU" will be displayed and the fault alarm signal will be output.
·Restart from 0 Hz after the waiting time
has elapsed.
·"LU" will be displayed, but the fault
alarm signal will not be output.
·After the waiting time has elapsed, the
inverter restarts at the frequency applied
before the ride-through occurrence.
·"LU" will be displayed, but the fault
alarm signal will not be output.
·After the waiting time has elapsed, the
inverter will sense the motor rotation
through speed search function and
