(2) Instantaneous power failure during stop alarm output during under-voltage
Select yes/no of alarm output when instantaneous power failure or under-voltage occurs with b004.
Alarm outputs while control power of inverter remains.
(example5) b004 : 00
(example6) b004 : 01
(3) It is possible to use an output by assigning the signal (IP: 09) during instantaneous stop, by setting (RNT:
11) during under-voltage to an intelligent output terminal 11-15(C021-C025) or alarm relay output terminal
(C026).
