These adjustments can be ignored at theinitial startup.With this parameter a regulated output voltage in relation to the ratedfrequency can be adjusted. For that reason voltage variations at the inputas well as in the intermediate circuit only have a small influence on theoutput voltage (U/fcharacteristic). The function allows, among otherthings, an adaption of the output voltage to special motors.Adjustment range:Resolution:Factory setting:Note: 1...650 V (off) 1V 650 V (off)EnterParameterVoltage stabilizationIn the example below the output voltage is stabilized to 230 V (0% boost).UN/UA250 V=230 V190 VUA bei UN = 250V unstabilizedUA bei UN = 250V stabilizedUA bei UN = 190V stabilizedUA bei UN = 190V unstabilizedUN = mains voltageUA= output voltage=50 HzfGB 17Operation of the UnitCarrier frequencyThe switching frequency with which the power modules are clocked canbe changed depending on the application.
