6.16.11 Cumulative operation time alarm setting
 : Cumulative operation time alarm setting
• Function
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)

6.16.12 Undervoltage trip
 : Undervoltage trip/alarm selection
• Function
This parameter is used for selecting the control mode when an undervoltage is detected. Trip
information is displayed as "  ".
 =  : The inverter is stopped. However, it is not tripped (Failure signal FL not activated).
The inverter is stopped when the voltage does not exceed 64 % or less of its rating.
 =  : Inverter is stopped. It is also tripped (Failure signal FL activated), only after detection of a voltage
not exceeding 64% or less of its rating.
 =  : Inverter is stopped. However, it is not tripped (Failure signal FL not activated). The inverter stop
(Failure signal FL not activated.), only after detection of a voltage not exceeding 50% of its rating.
Be sure to connect the AC reactor specified in 10.4.
