power interruption for 15 ms or more.)
1 The Inverter will continue operating if power is restored within 0.5 s.
(see note 1)
2 The Inverter will restart when power is restored. (see note 2)
Note 1. By setting n081 to 1, the Inverter will detect UV warning, turn OFF the output,
and wait for power restoration for 0.5 s if a momentary power interruption
occurs. If the power recovers within 0.5 s, the Inverter will restart after speed
searching. If the momentary power interruption continues more than 0.5 s, the
Inverter will detect UV1.
Note 2. By setting n081 to 2, the Inverter will detect UV warning, turn OFF the output,
and wait for power restoration if a momentary power interruption occurs. When
the power recovers, the Inverter will restart after speed searching.

Caution
!
·The fault retry function automatically resets and restarts the Inverter in the case the
Inverter has an overvoltage fault or an overcurrent fault during operation.
·In the case of any other fault, the protective function operates instantly and the fault
retry function does not operate.
·This function is to be used only if the user does not want to interrupt the mechanical
system, even if this function may damage the Inverter.
·Set a multi-function output (n057 to n059) to the following so that the fault retry signal
will be output.
Set value: 14 for fault retries
The Inverter may break if the fault retry function is used.
If the Inverter breaks, take the following measures:
Be sure to install a no-fuse breaker (NFB).
Provide the Inverter and peripheral machines with a sequence so
that the machines will stop operating when the Inverter has an
operational fault.
