setting is 0–20 mA or 4–20 mA, and the unit is in current (mA).
 When you set the analog input ACI to 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. Values between two points are calculated by a linear equation.
 The output percentage is 0% when the ACI input value is lower than the lowest point setting.
Example: Pr.03-57=2mA; Pr.03-58=10%. The output becomes 0% when AVI1 input is lower than
2mA. If the ACI input varies between 2mA and 2.1mA, the drive’s output frequency oscillates
between 0% and 10%.
 Positive AVI2 Voltage Lowest Point

Positive AVI2 Voltage Proportional Highest Point
Default: 100.00
Settings -100.00–100.00%
 When you set the positive voltage AVI2 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. Values between two points are calculated by a linear equation.
 The output % will become 0% when the AVI2 input value is lower than low point setting.
For example: Pr.03-63=1V; Pr.03-64=10%. The output will become 0% when the input is lower
than 1 V. If the AVI input varies between 1 V and 1.1 V, the drive’s output frequency oscillates
between 0% and 10%.
 When AVI1 Selection (Pr.03-28) is 0–10 V, the setting ranges for Pr.03-51, Pr.03-53, and Pr.03-55
must be 0.00–10.00 or 0.00–20.00.
