Low Voltage Fault Trip
When inverter input power is lost and the internal DC link voltage drops below a certain voltage
level, the inverter stops output and a low voltage trip occurs.

Low Voltage Fault Trip Setting Details
If the multi-functional relay or terminal output is set to 11 (Low Voltage), a
low voltage trip condition arises. The relay or terminal output is on after the
trip delay time (Pr.81: LVT Delay).
