(2) Instantaneous power failure/under voltage alarm output during stop
① b019 decides whether alarm generates or not when instantaneous power failure or under-
voltage occurs.
② Alarm occurs while control power of inverter remains.
③ The waveform of alarm outputs at an instantaneous power failure and under-voltage
during stop is following.
Fig. 8- 3 The waveform of alarm outputs at instantaneous power failure/under
④ It is possible to use an output by assigning the signal (IP=08) during instantaneous stop,
by setting (UV=09) during under-voltage to an intelligent output terminal 11-14(o001-
o004) or alarm relay output terminal.
⑤ Refer to the reset description in case of the power failure for more than 1 second.
When b016 is set to 0,
voltage alarm output during stop (b016=0)
