F0.3 Upper freq Setting range：0.0 Hz ~ [F0.4]
It can set hysteresis function, avoiding set fluctuation around zero freq. When decreasing set
freq is lower than f (f=lower freq -2Hz), inverter runs under zero freq. Increasing set freq, when
set freq is lower than lower freq, inverter runs under zero freq shown as fig 6-3：
