Chapter 12 Description of Parameter SettingsME300
If Pr.03-57 = 2 mA; Pr.03-58 = 10%, then the output becomes 0% when the AVI 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 % becomes 0% when the positive voltage AVI input value is lower than lowest point
setting.
For 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%.
