Setting a Predefined V/f Pattern
Setting the V/f Pattern
Choose the V/f pattern that meets the application demands from the table below. Set the correct value to E1-03. The V/f
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.

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 and motor exceeds
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.
