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.

The input voltage setting determines the overvoltage and undervoltage detection levels, the operation levels of the braking
transistor, the KEB function, and the overvoltage suppression function.

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 predefined
V/f patterns (setting 0 to E) from which to select, each with varying voltage profiles, saturation levels (frequency at which
maximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern is available (setting F) that
requires the user to create the pattern using parameters E1-04 through E1-10.
n
E1-03: V/f Pattern Selection
Selects the V/f pattern for the drive and motor from 15 predefined patterns or creates a custom V/f pattern.

<1> 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 E)
Choose the V/f pattern that best meets the application demands from
. These settings are available only in
V/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.
