1.5 E: Motor ParametersE parameters cover V/f pattern and motor data settings.u E1: V/f Pattern for Motor 1n E1-01: Input Voltage SettingAdjusts the levels of some protective features of the drive (overvoltage, Stall Prevention, etc.). Set this parameter to the nominalvoltage of the AC power supply.NOTICE: Set parameter E1-01 to match the input voltage of the drive. Drive input voltage (not motor voltage) must be set in E1-01 for theprotective features to function properly. Failure to set the correct drive input voltage will result in improper drive operation.No. Parameter Name Setting Range DefaultE1-01 Input Voltage Setting 445.6 to 733.1 V 661.3 VE1-01 Related ValuesThe input voltage setting determines the overvoltage and undervoltage detection levels, the KEB function, and the overvoltagesuppression function.Voltage Setting Value of E1-01 (Approximate Values)Uv Detection Level (L2-05)600 V Class All settings 475 Vn V/f Pattern Settings (E1-03)The drive uses a V/f pattern to adjust the output voltage relative to the frequency reference. There are 15 different predefinedV/f patterns (setting 0 to E) from which to select, each with varying voltage profiles, saturation levels (frequency at whichmaximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern is available (setting F) thatrequires the user to create the pattern using parameters E1-04 through E1-10.n E1-03: V/f Pattern SelectionSelects the V/f pattern for the drive and motor from 15 predefined patterns or creates a custom V/f pattern.No. Parameter Name Setting Range DefaultE1-03 V/f Pattern Selection 0 to F <1> F <2><1> Settings 0 through E are not available in OLV/PM (A1-02 = 5).<2> Parameter is not reset to the default value when the drive is initialized using A1-03.Setting a Predefined V/f Pattern (Setting 0 to F)Choose the V/f pattern that best meets the application demands from the table below. These settings are available only inV/f Control modes. Set the correct value to E1-03. Parameters E1-04 to E1-13 can only be monitored, not changed.Note: 1. Setting an improper V/f pattern may result in low motor torque or increased current due to overexcitation.2. Drive initialization does not reset parameter E1-03.Table 1.15 Predefined V/f PatternsSetting Specification Characteristic Application0 50 HzConstant torque For general purpose applications.
