n E1-01: Input Voltage Setting
Adjusts the levels of some protective features of the drive (overvoltage, Stall Prevention, etc.). Set this parameter to the nominal
voltage 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 the
protective features to function properly. Failure to set the correct drive input voltage will result in improper drive operation.
No. Parameter Name Setting Range Default
E1-01 Input Voltage Setting 190 to 240 V <1> 230 V <1>
<1> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
E1-01 Related Values
The input voltage setting determines the overvoltage and undervoltage detection levels, the KEB function, and the overvoltage
suppression function.

(Approximate Values)
Uv Detection Level (L2-05)
200 V Class All settings 190 V
400 V Class
Setting > 460 V 440 V
Setting ≥ 400 V 380 V
Setting < 400 V 350 V
n V/f Pattern Settings E1-04 to E1-13
If E1-03 is set to a preset V/f pattern (i.e., a value other than F), the user can monitor the V/f pattern in parameters E1-04
through E1-13. To create a new V/f pattern, set E1-03 to F. Refer to V/f Pattern on page 135 for an example custom V/f
pattern.
Note: Certain E1-oo parameters might not be visible depending on the control mode. Refer to Parameter List on page 279 for details.

E1-04 Maximum Output Frequency 40.0 to 240.0 Hz <1>
E1-05 Maximum Voltage 0.0 to 255.0 V <2> <1>
E1-06 Base Frequency 0.0 to 240.0 kHz <1>
E1-07 Middle Output Frequency 0.0 to 240.0 kHz <1>
E1-08 Middle Output Frequency Voltage 0.0 to 255.0 V <2> <1>
E1-09 Minimum Output Frequency 0.0 to 240.0 kHz <1>
E1-10 Minimum Output Frequency Voltage 0.0 to 255.0 V <2> <1>
E1-11 Middle Output Frequency 2 0.0 to 240.0 kHz 0.0 Hz <3>
E1-12 Middle Output Frequency Voltage 2 0.0 to 255.0 V <2> 0.0 V <3>
E1-13 Base Voltage 0.0 to 255.0 V <2> 0.0 V
<1> Default setting is determined by the control mode.
<2> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
<3> Parameter ignored when E1-11 and E1-12 are set to 0.0.
