If input power is disconnected during inverter operation and internal DC voltage decreases lower
than a certain voltage, the inverter disconnects the output and displays low voltage ‘2 (Low
Voltage 2)'.
Even if the voltage increases and goes back to the normal state, unlike a low voltage fault, it
remains in a fault state until the user unlocks the fault state.

When the multi-function input terminal is set as the output block signal terminal and the signal is
input to the terminal, then the operation stops.

When the operation of the multi-function input terminal is set to ‘5 (BX)’ and is turned
on during operation, the inverter blocks the output and ‘BX’ is displayed on the keypad
display. While ‘BX’ is displayed on the keypad screen, the inverter’s operation
information including the operation frequency and current at the time of the BX signal
can be monitored. The inverter resumes operation when the BX terminal turns off and
operation command is input.
6.3.5 Trip Status Reset
Restart the inverter, using the keypad or analog input terminal, to reset the trip status.
