 When you set the negative voltage AUI 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 not limits. There is a linear calculation between two points.
 The output percentage becomes 0% when the negative AUI input value is lower than the lowest
point setting.
For example:
If Pr.03-69 = -1 V; Pr.03-70 = 10%, then the output becomes 0% when the AUI input is ≥ -1V. If
the AUI input swings] between -1 V and -1.1 V, the drive’s output frequency oscillates between
0% and 10%.
