Fault Retry (N082) - Omron SYSDRIVE 3G3MV SERIES User Manual

Advanced Operation
Note 2. 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 interrup-
tion continues more than 0.5 s, the Inverter will detect UV1.
Note 3. 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.
Note 4. By setting n081 to 5 to 100, 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, an
operation prohibit status will be created internally for the set value times 0.1 s. When the
operation prohibit status is cleared, the Inverter will restart after speed searching.
Note 5. If power is completely discharged, operation will be the same as for initially turning ON the
power supply regardless of the setting of n081. (Operation will start immediately when the
RUN signal turns ON.)

6-10-5 Fault Retry (n082)

Caution 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.
• 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
