Continued 2: Square V/f curve
Below the rated frequency, the
relationship between the output voltage
and the output frequency of the AC drive
changes according to the square curve.
This curve is applicable to scenarios with
light loads that seldom change, such as
fans and water pumps.
3: 1.2‑power V/f curve
Below the rated motor frequency, the
relationship between the output voltage
and the output frequency of the AC drive
changes according to the 1.2‑power
curve.
4: 1.4‑power V/f curve
Below the rated motor frequency, the
relationship between the output voltage
and the output frequency of the AC drive
changes according to the 1.4‑power
curve.
6: 1.6‑power V/f curve
Below the rated motor frequency, the
relationship between the output voltage
and the output frequency of the AC drive
changes according to the 1.6‑power
curve.
