 When you set the positive voltage AVI to the Frequency command, 100% corresponds to Fmax
(Pr.01-00 Maximum Operation Frequency) and the motor runs in the forward direction.
 The requirement for these three parameters (Pr.03-63, Pr.03-65 and Pr.03-67) is Pr.03-63 <
Pr.03-65 < Pr.03-67. The values for three proportional points (Pr.03-64, Pr.03-66 and Pr.03-68)
have no limits. There is a linear calculation between two points.
 The output percentage becomes 0 % when the positive voltage AVI input value is lower than the
lowest point setting.
Example: If Pr.03-63 = 1 V; Pr.03-64 = 10%, then the output becomes 0% when the AVI input is
≤ 1 V. If the AVI input swings between 1 V and 1.1 V, the drive’s output frequency oscillates
between 0% and 10%.
