When output phase loss, inverter stops and alarms LF.
Output phase loss protection
06-20(P.262)=“1”, When output phase loss, inverter stops and alarms”LF”; when 06-20(P.262)=“0”, the function
will be off.

Low voltage level
When inverter input voltage is too low, which the DC bus voltage lower than 06-21(P.705)
value, inverter enters
low voltage protection state, it will stop output and idle stop.

Regenerative brake operation level
06-22(P.706) is regenerative brake (brake resistor) operation level. When DC bus voltage is over 06-22(P.706)
value, regenerative brake (brake resistor) operation starts.
