Low Voltage Fault Trip Setting Details
Code Description
PRT-81
LVT Delay
If the code value is set to ‘11 (Low Voltage)’, the inverter stops the output first
when a low voltage trip condition occurs, then a fault trip occurs after the low
voltage trip decision time elapses. The warning signal for a low voltage fault trip
can be provided using the multi-function output or a relay. However, the low
voltage trip delay time (LVT Delay time) does not apply to warning signals.

If input power is disconnected during inverter operation and internal DC voltage decreases
lower than a certain voltage, the inverter disconnects the output and dis
plays 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.
