E1: V/f Characteristics

n 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.

E1-01
<1> The setting range and default value shown here are for 200 V class drives. Double this for 400 V class units.
E1-01 Related Values
The input voltage setting determines the over-/undervoltage detection level and the operation levels of the braking transistor.

400 V Class
Note: The braking transistor operation levels are valid for the drive internal braking transistor. If an external CDBR braking chopper is used, refer
to the instruction manual of that unit.
n 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.
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 193.
2.
Set the V/f pattern. Refer to V/f Pattern Settings E1-04 to E1-10 on page 193.
n V/f Pattern Setting Examples
This section provides examples of how to set a V/f pattern using E1-04 to E1-10.

Characteristic
For general purpose applications. Torque remains
Constant torque
constant regardless of changes to speed.
For fans, pumps, and other applications that require
Derated torque
torque derating relative to the load.
Select high starting torque when:
• Wiring between the drive an motor exceeds 150 m
High starting torque
• A large amount of starting torque is required
• An AC reactor is installed
When operating at greater than 60 Hz the output
Constant output
voltage will be constant.
