Restart Upon Momentary Power Interruption/Undervoltage, Overvoltage/Overcurrent - Omron SYSDRIVE MX2 SERIES User Manual

Restart Upon Momentary Power Interruption/Undervoltage, Overvoltage/Overcurrent

Whether to trip or restart the Inverter upon momentary power interruption/undervoltage or
overvoltage/overcurrent can be selected.
Restart upon Momentary Power Interruption/Undervoltage, Overvoltage/Overcurrent
When a restart function is selected under Retry Selection (b001), the Inverter restarts
repeatedly for the number of times set in b005 in the case of momentary power interruption/
undervoltage, or in b010 in the case of overvoltage/overcurrent, and then trips at the next
restart. The Inverter does not trip when unlimited restart is set. Unlimited restart can be set only
for Momentary Power Interruption/Undervoltage Restart (b005).
b004 can be used to select whether the Inverter trips or not when a momentary power
interruption or undervoltage occurs while stopped.
When selecting a restart function, set the following restart conditions according to the system.
A desired function can be selected from 0 Hz restart, frequency matching restart, frequency
matching deceleration trip, and frequency pull-in restart.
Even when the Inverter is restarting, an E09 (undervoltage) trip occurs if an undervoltage
condition continues for 40 seconds.
