ACI Proportional Highest Point
Factory Setting: 100.00
Settings 0.00~100.00 %
 When Pr. 03-29 = 1, ACI setting is 0-10 V and the unit is in voltage (V).
 When Pr. 03-29 ≠ 1, ACI setting is 0-20 mA or 4-20 mA and the unit is in current (mA).

When setting analog input ACI to frequency command, it 100 % corresponds to Fmax (Pr. 01-00
Max. operation frequency).
 The 3 parameters (Pr. 03-57, Pr. 03-59 and Pr. 03-61) must meet the following argument:
Pr. 03-57 < Pr. 03-59 < Pr. 03-61. The 3 proportional points (Pr. 03-58, Pr. 03-60 and Pr. 03-62)
doesn’t have any limit. Between two points is a linear calculation.
 The output % will become 0 % when the ACI input value is lower than low point setting.
For example:
If Pr. 03-57 = 2 mA; Pr. 03-58 = 10 %, then the output will become 0 % when AVI input is
≤ 2 mA.
If the ACI input is swing between 2 mA and 2.1 mA, drive’s output frequency will beats between 0
% and 10 %.

AVI Voltage Lowest Point
Factory Setting: 0.00
Settings 0.00~10.00 V

AVI Voltage Proportional Lowest Point
Factory Setting: 0.00
Settings -100.00~100.00 %

AVI Voltage Mid-point
Factory Setting: 5.00
Settings 0.00~10.00 V

AVI Voltage Proportional Mid-point
Factory Setting: 50.00
Settings -100.00~100.00 %

AVI Voltage Highest Point
Factory Setting: 10.00
Settings 0.00~10.00 V

AVI Voltage Proportional Highest Point
Factory Setting: 100.00
Settings -100.00~100.00 %
 When setting positive voltage AVI to frequency command, it 100 % corresponds to Fmax
(Pr. 01-00 Max. operation frequency) and the motor runs in forward direction.

The 3 parameters (Pr. 03-63, Pr. 03-65 and Pr. 03-67) must meet the following argument:
Pr. 03-63 < Pr. 03-65 < Pr. 03-67. The 3 proportional points (Pr. 03-54, Pr. 03-66 and Pr. 03-68)
doesn’t have any limit. Between two points is a linear calculation.
 The output % will become 0 % when positive voltage AVI input value is lower than low point
setting.
