6-4-2 Energy-saving Control Function

The energy-saving control function is enabled when the energy-saving command (setting 63) has been
set in a multi-function input (H1-01 through H1-06). Inputting the energy-saving command while there is
a light load causes the Inverter's output voltage to be reduced and saves energy. Turn OFF the energy-
saving command when a normal load is added.
Parameter b8-01 determines the Inverter's output voltage when the energy-saving command is input.
Set this value as a percentage of the V/f pattern's voltage. Parameter L2-04 (the voltage recovery time)
determines the rate at which the output voltage is changed when the energy-saving command is turned
ON or OFF.
Parameter b8-02 determines the lower limit frequency for the energy-saving function. The energy-sav-
ing command is enabled only when the frequency reference is above this lower limit and the motor
speed is within the "speed agree" range.
