5.5 E: Motor ParametersE parameters cover V/f pattern and motor data settings.u E1: V/f Characteristicsn E1-01: Input Voltage SettingSet the input voltage parameter to the nominal voltage of the AC power supply. This parameter adjusts the levels of someprotective features of the drive (overvoltage, Stall Prevention, etc.).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 of the drive to function properly. Failure to comply could result in improper drive operation.No. Parameter Name Setting Range DefaultE1-01 <1> Input Voltage Setting 155 to 255 V 230 V<1> The setting range and default value shown here are for 200 V class drives. Double this for 400 V class units.E1-01 Related ValuesThe input voltage setting determines the over-/undervoltage detection level and the operation levels of the braking transistor.Voltage Setting Value of E1-01 (Approximate Values)ov Detection Level BTR Operation Level Uv Detection Level200 V Class all settings 410 V 394 V 190 V(single-phase = 160 V)400 V Class setting ≥ 400 V 820 V 788 V 380 Vsetting < 400 V 740 V 708 V 350 VNote: The braking transistor operation levels are valid for the drive internal braking transistor. If an external CDBR braking chopper is used, referto the instruction manual of that unit.n V/f Pattern SettingsThe drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency reference.V/f Pattern Setup for V/f Control1. Set the input voltage for the drive. Refer to E1-01: Input Voltage Setting on page 193.2. Set the V/f pattern. Refer to V/f Pattern Settings E1-04 to E1-10 on page 193.n V/f Pattern Setting ExamplesThis section provides examples of how to set a V/f pattern using E1-04 to E1-10.Table 5.10 V/f Pattern ExamplesExample Specification Characteristic ApplicationA 50 HzConstant torque For general purpose applications.
