F3-03 to F3-08 define multi-point V/F curve.
You must set multi-p
oint V/F curve based on motor’s load characteristic. The three
voltage points and frequency points must satisfy: V1 < V2 < V3, f1 < f2 < f3. When
you set F1 (F3-03), F2 (F3-05) and F3 (F3-07), set F3-07 first, then F3-05 and finally
F3-03.

Output frequency
Output voltage and output frequency change according to square curve when below
rated frequency. It is applicable to applications such as centrifugal fans where the load
is inversely proportional to the speed.
