0: Linear V/f curve
Under the rated frequency, the output voltage of the AC drive changes linearly
with the output frequency. This curve is suitable for general mechanical drive
applications such as large‑inertia fan acceleration, punch presses, centrifuges,
and water pumps.
1: Multi‑point V/f curve
The frequency ranges from 0.00 Hz to the rated motor frequency. The range of the
voltage points is 0.0% to 100.0%, which corresponds to the range of 0 V to the
rated motor voltage. The multi‑point V/f curve references are typically determined
based on load of the motor. Ensure that the following conditions are met: F3‑03
≤ F3‑05 ≤ F3‑07.
2: Square V/f curve
Under the rated frequency, the output voltage changes with the output frequency
of the AC drive according to the 2‑power curve. This curve is suitable for
applications with light loads that seldom change, such as fans and water pumps.
3: 1.2‑power V/f curve
Under the rated frequency, the output voltage changes with the output frequency
of the AC drive according to the 1.2‑power curve.
4: 1.4‑power V/f curve
Under the rated frequency, the output voltage changes with the output frequency
of the AC drive according to the 1.4‑power curve.
6: 1.6‑power V/f curve
Under the rated frequency, the output voltage changes with the output frequency
of the AC drive according to the 1.6‑power curve.
8: 1.8‑power V/f curve
Under the rated frequency, the output voltage changes with the output frequency
of the AC drive according to the 1.8‑power curve.
10: V/f complete separation mode
The output frequency and output voltage of the AC drive are independent of each
other. The output frequency is determined by the frequency source, and the
output voltage is determined by voltage source for V/f separation. This curve is
generally applicable to scenarios such as motor torque control.
11: V/f half separation mode
In this mode, the voltage (V) is proportional to the frequency (f). The relationship
between V and f can be set by the voltage source, and it is also related to the
rated motor voltage and rated motor frequency in group F1. Assume that the
voltage source input is X (0 to 100%), the relationship between V and f is as
follows: V/f = 2 x X x (Rated motor voltage)/(Rated motor frequency)
