[AI3 CONFIGURATION]
Can be accessed if an ER40 option card "In-/Out- extension" has been inserted
AI3A
• [AI3 assignment]
Read-only parameter, cannot be configured.
It displays all the functions associated with input AI3 in order to check, for example, for compatibility
problems.

0A
Read-only parameter, cannot be configured.

0 to 20.0 mA
0 mA
CrH3
• [AI3 max. value]
0 to 20.0 mA
20.0 mA
AI3F
• [AI3 filter]
0 to 10.00 s
0 s
Interference filtering.

: 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 ref100%
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.
• 0% corresponds to
[Min value]
(CrL3)
if the range is 0
...
100%.
• 0% corresponds to
if the range is -100%
...
+100%.
• 100% corresponds to
[AI3 max. value]
(CrH3)
.
AI3S
• [AI3 Interm. point Y]
0 to 100%
0%
Output delinearization point coordinate (frequency reference).
