=: 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 or DC 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 output a trip or an alarm, if the VIC value remains below the specified value for about
0.3 seconds. In such a case, trip "
e-18" and alarm "a-18" is displayed.
f633=0: Disabled....Not detected.
f633=1-100....The inverter will output a trip or an alarm, if the VIC input remains below the specified value
for about 0.3 seconds.
