E1-01: Input Voltage Setting
Set the input voltage parameter to the nominal voltage of the AC power supply. This parameter adjusts the levels of some
protective 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 the
protective features of the drive to function properly. Failure to comply could result in improper drive operation.

The input voltage setting determines the over-/undervoltage detection level and the operation levels of the braking transistor
as well as the KEB function and the overvoltage suppression function.

V/f Pattern Settings
The drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency reference.
There are 15 different preset V/f patterns to select from with varying voltage profiles, saturation levels (frequency at which
maximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern can be set up by programming
parameters E1-04 through E1-10.
V/f Pattern Setup for V/f Control
1.
Set the input voltage for the drive.
Refer to E1-01: Input Voltage Setting on page 169
2.
Set the V/f pattern by:
a) choosing one of the 15 preset V/f patterns (E1-03 = 0 to E).
b) select the custom V/f pattern (E1-03 = F, default setting).
3.
When using one of the 15 presets, E1-04 through E1-13 are automatically set. Refer to the description below.
For a custom V/f pattern, E1-04 through E1-13 must be adjusted manually.
Refer to V/f Pattern Settings E1-04 to
.
Open Loop Vector Control Setup for IM and PM Motors
In OLV only the user defined V/f pattern can be used.
Refer to V/f Pattern Settings E1-04 to E1-13 on page 172

E1-03: V/f Pattern Selection
This parameter can only be changed when the drive is operating in V/f Control. It allows the user to select the V/f pattern from
15 predefined patterns or to create a custom V/f pattern.
