The tables below show details on pre-defined V/f patterns.
• V/f Patterns for 0.1 to 4.0 kW Drives
The following graphs are for 200 V class drives. Double values when using a 400 V class
unit.
Table 1.31 Constant Torque Characteristics, Settings 0 to 3
Table 1.32 Derated Torque Characteristics, Settings 4 to 7
4 50 Hz, Heavy Duty 2
Derated torque
For fans, pumps, and other applications
that require torque derating relative to the
load.
5 50 Hz, Heavy Duty 1
6 50 Hz, Heavy Duty 1
7 50 Hz, Heavy Duty 2
8 50 Hz, mid starting torque
High starting torque
Select high starting torque when:
• Wiring between the drive an motor
exceeds 150 m
• A large amount of starting torque is
required
• An AC reactor is installed
9 50 Hz, high starting torque
A 60 Hz, mid starting torque
B 60 Hz, high starting torque
C 90 Hz (with 60 Hz base)
Constant output
When operating at greater than 60 Hz the
output voltage will be constant.
D 120 Hz (with 60 Hz base)
E 180 Hz (with 60 Hz base)
Setting = 0 50 Hz Setting = 1 60 Hz Setting = 2 60 Hz Setting = 3 72 Hz
Setting = 4 50 Hz Setting = 5 50 Hz Setting = 6 60 Hz Setting = 7 60 Hz
