ACI Highest Point
Default:
20.00 / 10.00 / 20.00
Settings Pr. 03-29 = 0, 0.00–20.00mA
Pr. 03-29 = 1, 0.00–10.00V
Pr. 03-29 = 2, 0.00–20.00mA

ACI Proportional Highest Point
Default: 100.00
Settings -100.00–100.00%
 When Pr. 03-29 = 1, ACI setting is 0–10V and the unit is in voltage (V). When Pr. 03-29 ≠ 1, ACI
setting is 0–20mA or 4–20mA 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 = 2 mA; Pr. 03-58 = 10 %. The output becomes 0 % when AVI input is lower than 2 mA.
If the ACI input varies between 2 mA and 2.1 mA, the drive’s output frequency oscillates between
0 % and 10%.

Positive AUI Voltage Lowest Point
Default: 0.00
Settings 0.00–10.00 V

Positive AUI Voltage Proportional Lowest Point
Default: 0.00
Settings -100.00–100.00 %

Positive AUI Voltage Mid-Point
Default: 5.00
Settings 0.00–10.00 V

Positive AUI Voltage Proportional Mid-Point
Default: 50.00
Settings -100.00–100.00 %

Positive AUI Voltage Highest Point
Default: 10.00
Settings 0.00–10.00 V

Positive AUI Voltage Proportional Highest Point
Default: 100.00
Settings -100.00–100.00 %
 When you set the positive voltage AUI to the frequency command, 100% corresponds to Fmax
(Pr. 01-00 maximum operation frequency) and the motor runs in the forward direction.
