Momentary Power Interruption/Trip Retry (Restart)
Restart During Momentary Power Interruption
• You can set whether the Inverter trips or retries (restarts) when a momentary power interruption or
undervoltage occurs.
• If the retry function is selected in retry selection b001, the Inverter retries for the number of times
set in b005 (for momentary power interruption) or b009 (for undervoltage), and trips on the next
time.
(Under the limitless retry setting, the Inverter doesn't trip.)
• You can use b004 to select whether the Inverter trips or not when a momentary power interruption
or undervoltage occurs during stop.
• When selecting the retry function, set retry condition b008 according to your system.
• If undervoltage is retained for 40 seconds even during retry operation, it results in E09
(undervoltage trip).
