Restart During Power Interruption, Undervoltage/Overvoltage, Overcurrent - Omron MX2 Series User Manual

7-7-2 Restart during Power Interruption, Undervoltage/Overvoltage,
Overcurrent
Select whether to have the inverter trip or restart if restart during power interruption, undervoltage/over-
voltage, overcurrent occurs.
Restart during Power Interruption, Undervoltage/Overvoltage,
Overcurrent
Power interruption/Undervoltage restart: When the Power Interruption/Undervoltage Restart Selection
(b001) is set to one of the restart options, the inverter repeats restart operation for the number of times
set in the Power Interruption Restart Count (b005) in the event of a momentary power interruption and
then trips.
Overvoltage/Overcurrent restart: When the Overvoltage/Overcurrent Restart Selection (b008) is set to
one of the restart options, the inverter repeats restart operation for the number of times set in the Over-
voltage/Overcurrent Restart Count (b010) in the event of an undervoltage, and then trips.
Only the Power Interruption Restart Count (b005) can be set to 01 (No limit), which causes the inverter
to trip.
In the Power Interruption/Undervoltage Trip Selection During Stop (b004), select whether or not to have
the inverter trip if a power interruption/undervoltage occurs during stop.
In the Power Interruption/Undervoltage Restart Selection (b001), select the restart condition according to
your system: 0-Hz restart, Frequency matching restart, Trip after frequency matching deceleration stop, or
Frequency pull-in restart.
If the inverter is in an undervoltage state continuously for 40 seconds during restart operation, an
Undervoltage protection (E09) trip will occur.

The inverter restarts if the power
interruption duration is shorter
than the set time. (Example 1)
The inverter trips if the power inter-
ruption duration is equal to or lon-
ger than the set time. (Example 2)
Set the wait time until the inverter
restarts.
