Positive AUI Voltage High Point
Settings 0.00~10.00V
Positive AUI Voltage Proportional High Point
Settings -100.00%~100.00%
When setting positive voltage AUI to frequency command, it 100% corresponds to Fmax (Pr.01-00
Max. operation frequency) and the motor runs in forward direction.
Three of the positive voltage AUI points can be set according to user's demand on voltage and
proportion, there is no setting limit for AUI points.
Negative AUI Voltage Low Point
Settings 0.00~-10.00V
Negative AUI Voltage Proportional Low Point
Settings -100.00~100.00%
Negative AUI Voltage Mid Point
Settings 0.00~-10.00V
Negative AUI Voltage Proportional Mid Point
Settings -100.00~100.00%
Negative AUI Voltage High Point
Settings 0.00~-10.00V
Negative AUI Voltage Proportional High Point
Settings -100.00~100.00%
When setting negative voltage AUI to frequency command, it 100% corresponds to Fmax (Pr.01-00
Max. operation frequency) and the motor runs in reverse direction.
Three of the negative voltage AUI points can be set according to user's demand on voltage and
proportion, there is no setting limit for AUI points.
The 3 parameters (Pr03-69, Pr03-71 and Pr03-73) must meet the following argument: P03-69 <
P03-71 < P03-73. The 3 proportional points (Pr03-70, Pr03-72 and Pr03-74) doesn't have any limit.
Between two points is a linear calculation
The output % will become 0% when the negative AUI input value is lower than low point setting.
For example:
P03-63=-1V; P03-64 = 10%. The output will become 0% when AUI input is bigger than -1V. If the
AUI input is swing between -1V and -1.1V, drive's output frequency will beats between 0% and
10%.
