User V/F pattern operation
Group Code Parameter Name Setting Range Initial Unit
Function group 1 F30 [V/F pattern] 2 0 ~ 2 0
F31 [User V/F frequency 1] - 0 ~ 400 12.50 Hz
~ ~
F38 [User V/F voltage 4] - 0 ~ 100 100 %

Select F30 to 2 {User V/F}.

User can adjust the Volt/Frequency ratio according to V/F pattern of special motors and
load characteristics.
CAUTION
In case of using a standard induction motor, setting V/F values much higher than linear V/F
pattern, it could result a torque shortage or motor overheating due to windings over-
energizing.
When User V/F pattern is active, F28 - [Torque Boost in forward direction] and F29 - [Torque
Boost in reverse direction] are deactivated.

- 40 ~ 110 100 %

This function is used to adjust the output voltage of the inverter. This is useful when you
use a motor that has a rated voltage lower than the input voltage.
