F09.01－F09.06 is the user-definable V/f curve.
• If F09.00 = 4 (user-definable curve), F09.06 is
enabled.
• The V/f curve can be defined by connecting 3
points of (V1, F1), (V2, F2) and (V3, F3), to
adapt to special load.
• According to the actual operation, set proper
curve to meet the requirements of load
characteristics.

In order to compensate the torque drop at low
frequency, the inverter can boost the voltage so
as to boost the torque.
• No matter what kind of V/f curve is set by
F09.00, the torque boost is enabled.
If F09.07 = 0, auto torque boost is enabled.
• If F09.07 is set as non-zero, manual torque
boost is enabled.
F09.08 is relative to percentage of motor’s rated
frequency (F08.03).
