FC-10=1, energy saving operation control is enabled. When inverter runs in idling or on light
load (output current of inverter< the setting value of FC-12), if the output frequency >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< the starting frequency of energy saving or load is
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.
