5.2.7 F09: Motor 1 V/f Control Parameters
Ref. code Name Description Setting Range [Default]
F09.00 V/f curve of motor 1 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 available.
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 1 (F3) F09.03 - 100.0 [0.0%]
F09.02 V/f voltage of motor 1 (V3) F09.04 - 100.0 [0.0%]
F09.03 V/f frequency of motor 1 (F2) F09.05 - F09.01 [0.0%]
F09.04 V/f voltage of motor 1 (V2) F09.06 - F09.02 [0.0%]
F09.05 V/f frequency of motor 1 (F1) 0.0 - F09.03 [0.0%]
F09.06 V/f voltage of motor 1 (V1) 0.0 - F09.04 [0.0%]
F09.01 - F09.06 is user-definable V/f curve.
• 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 1 0.0 - 30.0 [2.0%]
F09.08 Cut-off point used for manual torque boost of motor 1 0.0 - 50.0 (F08.03) [25.0%]
In order to compensate the torque drop at low frequency, 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.
• F09.07 ≠ 0, it is manually torque boost.
• F09.07 = 0, it is auto torque boost. User needs to
set 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.
