User Manual EM303B General Purpose Inverter 8.13.8 Energy Saving Operation FC-10=1, energy saving operation control is enabled. When inverter runs in idling or on light load (output current of inverter energy saving starting frequency (Set by FC-11), inverter will test load current automatically and make a record of time. If the setting time of FC-13 can meet energy saving needs, the output voltage shall be dropped to energy saving permitted range (Set by FC-14) to start energy saving operation. When output frequency increasing, inverter will withdraw from energy saving operation status. Output voltage will reset corresponding value.
If output current of inverter > the setting value of FC-12, automatic energy saving is disabled. See Figure 7-34 for operation process of automatic energy saving. Output Frequency （ Hz ） Output Voltage(%) Energy Saving Permitted Range FC-14 See Figure 7-34 Operation Process of Automatic Energy Saving In V/F control mode, the percentage of output voltage is the energy saving permitted range. 149 No. Function Range Unit Default Type Energy Saving Operation Options 0: Energy saving operation disabled 1:
