Configuration Mode (ConF)
S1A28692 03/2010 121
Parameters described in this page can be accessed by:
UIH2 [AI2 max. value]
0 to 10.0 V 10.0 V
AI2 voltage scaling parameter of 100%.
AI2F [AI2 filter]
0 to 10.00 s 0 s
Interference filtering.
AI2E [AI2 Interm. point X]
0 to 100% 0%
Input delinearization point coordinate. Percentage of the physical input signal.
0% corresponds to [Min value] if the range is 0 V 100%.
0% corresponds to if the range is -100%
V
+100%.
100% corresponds to [Max value].
AI2S [AI2 Interm. point Y]
0 to 100% 0%
Output delinearization point coordinate (frequency reference).
Percentage of the internal frequency reference corresponding to the [AI2 Interm. point X] (A12E) percentage of physical
input signal.
I_O- [INPUTS / OUTPUTS CFG] (continued)
AI3- [AI3 CONFIGURATION]
AI3A [AI3 assignment]
Identical to [AI1 assignment] (A11A) page 120.
AI3t [AI3 Type]
[Voltage +/-] (n10U)
0A [Current] (0A): 0 - 20 mA
CrL3 [AI3 min. value]
0 to 20.0 mA 0 mA
AI3 current scaling parameter of 0%.
CrH3 [AI3 max. value]
0 to 20.0 mA 20.0 mA
AI3 current scaling parameter of 100%.
AI3F [AI3 filter]
0 to 10.00 s 0 s
Interference filtering.
AI3L [AI3 range]
[0 - 100%] (POS)
POS
nEG
[0 - 100%] (POS): Unidirectional input
[+/- 100%] (nEG): Bidirectional input
Example: On a 4 - 20 mA input.
4 mA corresponds to reference -100%.
12 mA corresponds to reference 0%.
20 mA corresponds to reference +100%.
Since AI3 is, in physical terms, a bidirectional input, the [+/- 100%] (nEG) configuration must only be used if the signal applied
is unidirectional. A bidirectional signal is not compatible with a bidirectional configuration.
AI3E [AI3 Interm. point X]
0 to 100% 0%
Input delinearization point coordinate. Percentage of the physical input signal.
0% corresponds to [Min value] (CrL3) if the range is 0 V 100%.
0% corresponds to if the range is -100%
V
+100%.
100% corresponds to [AI3 max. value] (CrH3).
AI3S [AI3 Interm. point Y]
0 to 100% 0%
Output delinearization point coordinate (frequency reference).
Percentage of the internal frequency reference corresponding to the [AI3 Interm. point X] (A13E) percentage of physical
input signal.
I_O- [INPUTS / OUTPUTS CFG] (continued)
AU1- [VIRTUAL AI1]
AU1A [AIV1 assignment]
Virtual analog input 1 via the jog dial available on the front side of the product.
Identical to [AI1 assignment] (A11A) page 120
