● When you set the negative voltage AVI to the Frequency command, -100% corresponds to Fmax (Pr.01-00
Maximum Operation Frequency) and the motor runs in the reverse direction.
● The requirement for these three parameters (Pr.03-69, Pr.03-71 and Pr.03-73) is Pr.03-69 < Pr.03-71 < Pr.03-
73, the values for three proportional points (Pr.03-70, Pr.03-72 and Pr.03-74) have no limits. There is a linear
calculation between two points.
● The output percentage becomes 0 % when the negative voltage AVI input value is lower than the lowest point
setting.
Example:
If Pr.03-69 = -1V; Pr.03-70 = 10%, then the output becomes 0 % when the AVI input is ≥ -1V.
If the AVI input swings between -1V and -1.1V, drive’s output frequency oscillates between 0% and 10%.
