E1-01: Input Voltage Setting
n
Set the input voltage parameter to the nominal voltage of the connected AC power supply. This parameter adjusts the levels of some protective features
of the drive (i.e., overvoltage, Stall Prevention, etc.).
No.
E1-01
Note: The setting range shown here is for 200 V class drives. Double this value when working with 400 V class units.
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.
Detailed Description
The input voltage level determines the overvoltage detection level and the operation level of the braking transistor as shown in the table below.

This parameter is only available when using V/f Control. It allows the user to set the V/f pattern and drive input voltage as needed. When running a high-
speed or other type of special-purpose motor, this function can be used to fine-tune the amount of torque needed for the load.

Detailed Description
The drive operates utilizing a set V/f pattern to determine the appropriate output voltage level for each commanded speed. 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.
There are also settings for custom V/f patterns that will allow the programmer to manually set the V/f pattern using parameters E1-04 through E1-10.
Using parameter E1-03, the programmer can select one of the preset V/f patterns or chose between a custom V/f pattern with an upper voltage limit (E1-03
= "F: Custom V/f").
