n V/f Pattern Setting Examples
This section provides examples of how to set a V/f pattern using E1-04 to E1-10.
Example Specification
A
B 60 Hz (default setting)
C 60 Hz (with 50 Hz base)
D 72 Hz (with 60 Hz base)
E 50 Hz, Heavy Duty 2
F 50 Hz, Heavy Duty 1
G 50 Hz, Heavy Duty 1
H 50 Hz, Heavy Duty 2
I 50 Hz, mid starting torque
J 50 Hz, high starting torque
K 60 Hz, mid starting torque
L 60 Hz, high starting torque
M 90 Hz (with 60 Hz base)
N 120 Hz (with 60 Hz base)
O 180 Hz (with 60 Hz base)
The following tables show details on V/f patterns.
The following graphs are for 200 V class drives. Double the values when using a 400 V class
drive.

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