Individual Functions6-117 Energy-savingTo perform energy saving, set b8-01 (Energy Saving Mode Selection) to 1. Energy-saving control can be per-formed using both V/f control and vector control. The constants to be adjusted are different for each. In V/fcontrol, adjust b8-04 to b8-06, and in vector control, adjust b8-02 and b8-03.Related Constants* 1. The factory setting is 1.0 when using flux vector control.* 2. The factory setting is 2.00 s when Inverter capacity is 55 kW min.The factory setting will change when the control method is changed. The open-loop vector factory setting is given.* 3. By setting E2-11 (Motor rated output) the appropriate value will be set.* 4. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.Con-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torb8-01Energy-sav-ing modeselectionSelect whether to enable or dis-able energy-saving control.0: Disable1: Enable0 or 1 0 No A A A A 1CCHb8-02 Energy-sav-ing gainSet the energy-saving gain withthe vector control method.0.0 to10.00.7*1 Yes No No A A 1CDHb8-03Energy-sav-ing filter timeconstantSet the energy-saving filter timeconstant with the vector controlmethod.0.00 to10.000.50 s*2 Yes No No A A 1CEHb8-04Energy-sav-ing coeffi-cientSet the maximum motor effi-ciency value.Set the motor rated capacity inE2-11, and adjust the value by5% at a time until output powerreaches a minimum value.0.0 to655.00288.20*3*4No A A No No 1CFHb8-05Power detec-tion filtertime constantSet the time constant for outputpower detection.0 to2000 20 ms No A A No No 1D0Hb8-06Search opera-tion voltagelimiterSet the limit value of the voltagecontrol range during searchoperation.Perform search operation tooptimize operations usingminute variations in voltageusing energy-saving control.
