 When Pr.03-29 = 1, the ACI setting is 0–10 V 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%.
