6.19.12 Undervoltage trip
H : Undervoltage trip/alarm selection
• Function
This parameter is used for selecting the control mode when an undervoltage is detected. Trip
information is displayed as "WR".
H=: The inverter is stopped. However, it is not tripped (Failure signal FL not activated).
The inverter is stopped when the voltage does not exceed 60 % or less of its rating.
H=: Inverter is stopped. It is also tripped (Failure signal FL activated), only after detection of a
voltage not exceeding 60% or less of its rating.
H=: 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 DC reactor specified in 10.4.
