Chapter 12 Description of Parameter SettingsC2000
12.1-03-26
The requirement for these three parameters (Pr. 03-69, Pr. 03-71 and Pr. 03-73) is Pr. 03-69 < Pr.
03-71 < Pr. 03-73. The values for three proportional points (Pr. 03-70, Pr. 03-72 and Pr. 03-74)
have not limits. Values between two points are calculated by a linear calculation
.
The output % becomes 0% when the negative AUI input value is lower than the lowest point
setting. For example:
Pr. 03-69 = -1V; Pr. 03-70 = 10%, then the output becomes 0% when the AUI input is ≥ -1V. If the
AUI input varies between -1 V and -1.1 V, the drive’s output frequency oscillates between 0%
and 10%.
