This is useful when using a motor with a lowerrated voltage than the main input voltage. When this isset at 100%, inverter outputs its rated voltage.FU1► User freq 436 60.00 Hz3660.00Output Voltage100%Factory Default: 60.00 Hz 60.00FU1► User volt 437 100 %100These functions are available only when ‘User V/F’ isselected in FU1-29 [V/F pattern]. Users can make thecustom V/F pattern by setting four points between FU1-22 [Starting Frequency] and FU1-21 [Base Frequency].37Factory Default: 100 % 10050%When set at 50%FU1-21 [Base Freq]OutputFrequency☞ Note: The inverter output voltage does notexceed the main input voltage, even thoughFU1-38 is set at 110%.Output Voltage100%FU1-37FU1-35FU1-33FU1-31FU1-30FU1-32[User V/F]FU1-36FU1-34OutputFrequencyFreq. Base☞ Note: When the ‘User V/F’ is selected, the torque boostof FU1-26 through FU1-28 is ignored.FU1-39: Energy Save LevelFU1► Energy save39 0 %39Factory Default: 0 % 0This function is used to reduce the output voltage inapplications that do not require high torque and currentat its steady speed. The inverter reduces its outputvoltage after accelerating to the reference frequency(steady speed) if the energy save level is set at 20%.This function may cause over-current trip due to the lackof output torque in a fluctuating load.This function does not work with 0% set point value.094
