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.
6.3.4 Output Block via the Multi-function Terminal
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.
