Set 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 curve is active, F28 - [Torque Boost in forward direction] and F29 - [Torque Boost
in reverse direction] are deactivated.
