AI3 lower limit
Used to define the relationship between the
analog input
voltage and its corresponding
setting. When the analog input voltage exceeds
the range from the upper limit to the lower limit,
the upper limit or lower limit is used.
When the analog input is current input, 0mA
±
20mA current corresponds to 0V
±10V voltage.
In different applications, 100.0% of the analog
setting corresponds to different nominal values.
See the descriptions of each application section
for details.
The following figure illustrates the cases of
several settings:

AI3/AI4
Input filter time: to adjust the sensitivity of analog
input. Increasing the value properly can enhance
analog input anti
-
interference but may reduce the
sensitivity of analog input.
Note: AI3 and AI4 can support 0
±10V/0±
20mA
input. When AI3 and AI4 select 0
±2
0mA input,
the corresponding voltage of 20mA is 10V.
