Figure 9-3: AI1 Signal Filtering
2.2.6 AI1 signal range ID379
With this parameter you can select the AI1 signal range.
0 DIN 4
1 Signal range 0 – 20 mA
2 Signal range 4 – 20 mA
3 Signal range 0 – 10V
4 Signal range 2 – 10V
Note: The selections have no effect if par. 2.2.7 > 0%, or par. 2.2.8 < 100%.
If the value of par. 2.2.6 is set to 0, AI1 functions as digital input 4. See par. 2.2.4.
2.2.7
2.2.8
AI1 custom setting minimum
AI1 custom setting maximum
ID380
ID381
Set the custom minimum and maximum levels for the AI1 signal within 0 – 10V.
2.2.9 AI1 signal inversion ID387
By setting the parameter value to 1 the AI1 signal inversion takes place.
2.2.10 AI1 signal filter time ID378
This parameter, given a value greater than 0, activates the function that filters out
disturbances from the incoming analog V
in
signal.
Long filtering time makes the regulation response slower. See Figure 9-3.
2.2.11 AI2 signal selection ID388
Connect the AI2 signal to the analog input of your choice with this parameter. See
par. 2.2.5 for the value setting procedure.
