Input Phase Detection Level
Inp Ph Loss Lvl
When ripple is observed in the DC bus, expansion of the input bias is
calculated. This value becomes the input phase if the difference between the
maximum and minimum values of the ripple is greater than the value set to
L8-06.
Detection Level = 100% = Voltage class x √ 2
