All parameters
No. Name/Value
1302 MAXIMUM AI1 Defines the maximum %-value that corresponds to
-100.0...100.0% Value in percent of the full signal range.
1303 FILTER AI1
0.0...10.0 s
1304 MINIMUM AI2
-100.0...100.0% See parameter
1305 MAXIMUM AI2 Defines the maximum %-value that corresponds to
-100.0...100.0% See parameter
1306 FILTER AI2
0.0...10.0 s
Description
maximum mA/(V) signal for analog input AI1. When used as
a reference, the value corresponds to the reference
maximum setting.
=
0...20 mA 0...100%
=
4...20 mA 20...100%
=
-10...10 mA -50...50%
Example: If AI1 is selected as the source for external
reference REF1, this value corresponds to the value of
parameter 1105 REF1
Example: If the maximum value for analog input is 10 mA,
the percent value for 0...20 mA range is:
(10 mA / 20 mA) · 100% = 50%
Defines the filter time constant for analog input AI1, ie the
time within which 63% of a step change is reached.
