204 Actual signals and parameters
1302 MAXIMUM AI1 Defines the maximum %-value that corresponds to
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 MAX.
100.0%
-100.0…100.0% Value as a percentage of the full signal range.
Example: If the maximum value for analog input is 10 mA,
the percentage value for 0…20 mA range is:
(10 mA / 20 mA) · 100% = 50%
1 = 0.1%
1303 FILTER AI1 Defines the filter time constant for analog input AI1, ie, the
time within which 63% of a step change is reached.
0.1 s
0.0…10.0 s Filter time constant 1 = 0.1 s
1304 MINIMUM AI2 Defines the minimum %-value that corresponds to minimum
mA/(V) signal for analog input AI2. See parameter 1301
MINIMUM AI1.
20%
-100.0…100.0% See parameter 1301 MINIMUM AI1.1 = 0.1%
1305 MAXIMUM AI2 Defines the maximum %-value that corresponds to
maximum mA/(V) signal for analog input AI2. See
parameter 1302 MAXIMUM AI1.
100.0%
-100.0…100.0% See parameter 1302 MAXIMUM AI1.1 = 0.1%
1306 FILTER AI2 Defines the filter time constant for analog input AI2. See
parameter 1303 FILTER AI1.
0.1 s
0.0…10.0 s Filter time constant 1 = 0.1 s
