Select F30 to 2 {User V/F}.

User can adjust the Volt/Frequency ratio according to V/F pattern of specialized motors and load characteristics.

CAUTION

In case of using a standard induction motor, if this value is set much higher than linear V/F pattern, it could result in torque shortage or motor overheating due to over-energizing.

When User V/F pattern is active, F28 - [Torque Boost in forward direction] and F29 - [Torque Boost in reverse direction] are deactivated.
