● When Pr.03-29 = 1, the ACI setting is 0–10V and the unit is voltage (V).
● When Pr.03-29 ≠ 1, the ACI setting is 0–20 mA or 4–20 mA and the unit is current (mA).
● When you set the analog input ACI to the Frequency command, 100% corresponds to Fmax (Pr.01-00
Maximum Operation Frequency).
● The requirement for these three parameters (Pr.03-57, Pr.03-59 and Pr.03-61) is Pr.03-57 < Pr.03-59 < Pr.03-
61. The values for three proportional points (Pr.03-58, Pr.03-60 and Pr.03-62) have no limits. There is a linear
calculation between two points.
● The output percentage becomes 0 % when the ACI input value is lower than the lowest point setting.
Example:
If Pr.03-57 = 2 mA; Pr.03-58 = 10%, then the output becomes 0% when the ACI input is ≤ 2 mA.
If the ACI input swings between 2 mA and 2.1 mA, the drive’s output frequency oscillates between 0 % and 10 %.

● 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 = 1V; Pr.03-64 = 10%, then the output becomes 0 % when the AVI input is ≤ 1V.
If the AVI input swings between 1Vand 1.1V, the drive’s output frequency oscillates between 0% and 10%.
