■ F1901=1 Simple energy-saving Mode（V/f）
This code can execute energy saving with the setting of F1902、F1903.
Details for the references of F1902 和 F1903 description
■ F1901=2 Inverter operates on the conditions of auto energy saving.
After selecting this mode，No need to set the others parameters, Inverter can enter into the auto saving operation.
It performes obviously on the stable output, especially for the loading of fan and pump. The energy saving still enabled,
even if the loading is slightly changed.
■ F1902=0～50% Simple energy-saving rate.
This code used for setting the recommend rate of voltage droped under energy-saving mode.
For example：Rated output voltage: 300V, and F1902=20%, The output voltage will decrease to 300*(1-20%)=240V，
operation frequency no changing on the conditions of energy-saving mode.
Simple energy saving function can be adjusted by hand, making the related Voltage/Frequency in compliant with the load
charactertistics and torque charactertistics in order to get the best peformance of energy-saving.
