8.9 V/F Control Parameters

V/F curve selection
F8.00
V/F curve selection: used to select the V/F curve types to meet different load requirements.
0: linear V/F curve
1-9: 1.1-1.9 respectively VF power curve, as shown below;
10: VF square curve;
11: Custom VF curve; see [F8.01-F8.10];
VF default linear curve for most common situations; multi-idempotent curve and square VF curve are generally used for
VF fans or pumps to reduce the high-frequency current to achieve energy savings.
Note: multi-idempotent curve and square VF curve are calculated from the initial frequency set in F8.11, see
