Setting a Predefined V/f Pattern (Setting 0 to F)
Choose the V/f pattern that best meets the application demands from the table below. These settings are available only in
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. Parameter E1-03 is not reset when the drive is initialized.
Table 5.15 Predefined V/f Patterns
The following tables show details on predefined V/f patterns.
The following graphs are for 200 V class drives. Double the values when using a 400 V class drive.
Predefined V/f Patterns for models CIMR-E2A0004 to 2A0021 and CIMR-E4A0002 to 4A0011
Table 5.16 Constant Torque Characteristics, Settings 0 to 3
Table 5.17 Derated Torque Characteristics, Settings 4 to 7
Setting
<1> V/f pattern F allows setting up 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 will be equal to V/f pattern 1 of the predefined patterns.
Specification Characteristic Application
050 Hz
Constant torque
For general purpose applications. Torque remains constant regardless of
changes to speed.
160 Hz
2 60 Hz (with 50 Hz base)
3 72 Hz (with 60 Hz base)
4 50 Hz 2
Derated torque
For fans, pumps, and other applications where the required torque
changes as a function of the speed.
5 50 Hz 1
6 60 Hz 1
7 60 Hz 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 180 Hz (with 60 Hz base)
F <1> 60 Hz Constant torque
For general purpose applications. Used for general applications
requiring constant torque.
