6.18.12 Undervoltage trip

 : Undervoltage trip/alarm selection
 Function
=: The inverter is stopped. However, it is not tripped (Failure signal FL not activated).
=: Inverter is stopped. It is also tripped (Failure signal FL activated), only after detection of a voltage

This parameter allows you to set the inverter so that it will put out an alarm signal after a lapse of the
cumulative operation time set with .
"0.1" displayed on the monitor refers to 10 hours, and therefore "1" denotes 100 hours.
Ex.: 38.5 displayed on the monitor = 3850 (hours)
