Setting Specification Characteristic Application
0 50 Hz
Constant torque
For general purpose applications. Torque remains constant
regardless of changes to speed.
1 60 Hz
2 60 Hz (with 50 Hz base)
3 72 Hz (with 60 Hz base)
4 50 Hz, Heavy Duty 2
Variable torque
For fans, pumps, and other applications where the required
torque changes as a function of the speed.
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 and 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
Output voltage is constant when operating at greater than
60 Hz.
D 120 Hz (with 60 Hz base)
E 150 Hz (with 60 Hz base)
F
<1>
60 Hz Constant torque
For general purpose applications. Torque remains constant
regardless of changes to speed.
<1> Setting F enables a custom V/f pattern by changing parameters E1-04 to E1-13. When the drive is shipped, the default values for parameters E1-04
to E1-13 are the same as those of setting 1.
The following tables show details on predefined V/f patterns.
Predefined V/f Patterns for all HHP models:
• 400 V Class 414 A to 2000 A Heavy Duty, 466 A to 2250 A Normal Duty,
• 575 V Class 414 A to 2000 A Heavy Duty, 466 A to 2250 A Normal Duty,
• 690 V Class 414 A to 2000 A Heavy Duty, 466 A to 2250 A Normal Duty.
The values in the following graphs are specific to 400 V class drives. Multiply the values by 1.4375 for 575 V class drives.
Multiply the values by 1.725 for 690 V class drives.
