E1: V/f Pattern for Motor 1

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.
E1-01
<1> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
E1-01 Related Values
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.

<1> The braking transistor operation levels are valid for the drive internal braking transistor. When using a CDBR braking unit, refer to instruction
manual TOBPC72060000 or TOBPC72060001.
n 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.
No.
E1-03
<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
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.
