 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.
 Positive AUI input voltage is lower than Low Point, output proportional is 0%.
For example:
Pr. 03-63 = 1V; Pr. 03-64 = 10%. The output will become 0% when the input is lower than 1V. If
the AUI input varies between 1V and 1.1V, the drive’s output frequency oscillates between 0%
and 10%.
 Pr. 03-51~03-68 is able to set the open circuit corresponding function of analog input value and
max. operation frequency (Pr. 01-00), as shown in the figure below:

Negative AUI Voltage Highest Point
Default: 0.00
Settings -10.00–0.00 V

Negative AUI Voltage Proportional Highest Point
Default: 0.00
Settings -100.00–100.00 %

Negative AUI Voltage Mid-Point
Default: -5.00
Settings -10.00–0.00 V

Negative AUI Voltage Proportional Mid-Point
Default: -50.00
Settings -100.00–100.00 %

Negative AUI Voltage Lowest Point
Default: -10.00
Settings -10.00–0.00 V

Negative AUI Voltage Proportional Lowest Point
Default: -100.00
Settings -100.00–100.00 %
 When you set the negative voltage AUI to frequency command, 100% corresponds to Fmax (Pr.
01-00 maximum operation frequency) and the motor runs in the reverse direction.
