AC100 HIGH-PERFORMANCE VC INVERTER MANUAL FUNCTION PARAMETER SPECIFICATION1258.9 V/F Control ParametersF8.00 V/F curve selection Setting range:0-4 Factory default 0V/F curve selection: used to select the V/F curve types to meet different load requirements.0: linear V/F curve1-9: 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 forVF 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, seeF8.15F8.01 Self-setting voltage V1 Setting range: 0.0-100.0% Factory default 3.0%F8.02 Self-setting frequency F1 Setting range: 0.00-max frequency Factory default 1.00HzF8.03 Self-setting voltage V2 Setting range: 0.0-100.0% Factory default 28.0%F8.04 Self-setting frequency F2 Setting range: 0.00-max frequency Factory default 10.00HzF8.05 Self-setting voltage V3 Setting range: 0.0-100.0% Factory default 55.0%F8.06 Self-setting frequency F3 Setting range: 0.00-max frequency Factory default 25.00HzF8.07 Self-setting voltage V4 Setting range: 0.0-100.0% Factory default 78.0%F8.08 Self-setting frequency F4 Setting range: 0.00-max frequency Factory default 37.50HzF8.09 Self-setting voltage V5 Setting range: 0.0-100.0% Factory default 100.0%F8.10 Self-setting frequency F5 Setting range: 0.00-max frequency Factory default 50.00HzSelf-setting V/F curve: Users set the 1st /2nd /3rd /4th/5th voltage ratio of V/F curve corresponding to F1/F2/F3/F4/F5frequency based on rated output voltage 100%. Users set the 1st/2nd /3rd /4th/5th frequency of V/F curve corresponding toV1/V2/V3/V4/V5.
