6.2.10 F09: V/f Control Parameters
Ref. code Function Description Setting Range [Default]
F09.00
V/f curve of motor
0 - 4 [0]
Defines flexible V/f setting modes so as to meet requirements of different load characteristics.
• Four curves and one user-defined curve can be selected
according to the setting of F09.00.
0: Line. Sea line 0 in figure.
1: Square curve. Sea curve 1 in the figure.
2: 1.2 exponential curve. Sea curve 2 in the Figure.
3: 1.7 exponential curve. Sea curve 3 in the Figure.
4: User-defined curve.
F09.01 V/f frequency of motor (F3) F09.03 - 100.0 [0.0%]
F09.02
V/f voltage of motor (V3)
F09.04 - 100.0 [0.0%]
F09.03 V/f frequency of motor (F2) F09.05 - F09.01 [0.0%]
F09.04
V/f voltage of motor (V2)
F09.06 - F09.02 [0.0%]
F09.05 V/f frequency of motor (F1) 0.0 - F09.03 [0.0%]
F09.06
V/f voltage of motor (V1)
0.0 - F09.04 [0.0%]
F09.01 - F09.06 is 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
apply to special load.
• According to actual condition, set proper
curve to meet requirements of load
characteristics.
F09.07 Torque boost of motor 0.0 - 30.0 [2.0%]
F09.08
Cut-off point used for manual torque boost of motor
0.0 - 50.0 (F08.03) [25.0%]
In order to compensate the torque drop at low frequency, HD3N 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.
• F09.07 ≠ 0, it is manually torque boost.
• F09.07 = 0, it is auto torque boost.
User needs to set motor rated frequency
(F08.03); set according to nameplate or auto-
tune to get rated Rpm (F08.04); get motor stator
resistance (F08.07) by auto-tuning; set slip
compensation gain F09.09 = 100.0% to enable
slip compensation to achieve fine load
capability.
• F09.08 is relative to percentage of rated
frequency (F08.03).
F09.09
Slip compensation gain of motor
0.0 - 300.0 [0.0%]
F09.10 Slip compensation filter time of motor 0.01 - 10.00 [0.10s]
