f627=0: The inverter is stopped. However, it is not tripped (Failure signal FL not activated).
The inverter is stopped when the voltage does not exceed about 64 % of its rating.
f627=1: Inverter is stopped. It is also tripped (Failure signal FL activated), only after detection of a voltage
not exceeding about 64% 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 input AC reactor specified in section 10.4.

f633 : Analog input break detection level (VIC)
f644 : Operation selection of analog input break detection (VIC)
f649 : Fallback frequency
 Function
The inverter will trip if the VIC value remains below the specified value for about 0.3 seconds. In such
a case, trip "
e-18" and alarm "al05" is displayed.
f633=0: Disabled....Not detected.
f633=1-100....The inverter will trip if the VIC input remains below the specified value for about 0.3 seconds.
