2.2.9 AI1 signal inversion
By setting the parameter value to 1 the AI1 signal inversion takes place.
2.2.10 AI1 signal filter time
This parameter, given a value greater
than 0, activates the function that filters
out disturbances from the incoming
analogue U
Long filtering time makes the regulation
response slower. See Figure 1- 3
2.2.11 AI2 signal selection
Connect the AI2 signal to the analogue input of your choice with this parameter. See par. 2.2.5
for the value setting procedure.
2.2.12 AI2 signal range
0 Signal range 0...20 mA
1 Signal range 4...20 mA
Note! The selections have no effect if par. 2.2.13 > 0%, or par. 2.2.14 < 100%.
2.2.13 AI2 custom minimum
2.2.14 AI2 custom maximum
These parameters allow you to scale the input current signal between 0 and 20 mA.
Cf. parameters 2.2.7 and 2.2.8.
2.2.15 Analogue input AI2 signal inversion
See corresponding parameter 2.2.9.
