Figure 6-4 V/F Curve
When the F1.17 is selected to 1, the user can customize the V/F curve through
F1.18～F1.23, as shown in Figure 6-5. The V/F curve is defined by adding (V1, F1), (V2,
F2), and (V3, F3) three-point broken line, to adapt to special load characteristics.
This function parameter group is used to flexibly set the V/F curve required by the user,
as shown in Figure 6-5:

Note: When setting F1.18～F1.23, it is required to observe F1.18 < F1.20 < F1.22, F1.19 <
F1.21<F1.23; otherwise the E021 fault will be reported during operation.
