Description
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:

-10V
AI2
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: AI1 supports the 0–10V/0–20mA input.
When AI1 selects the 0–20mA input, the
corresponding voltage of 20mA is 10V. AI2
supports the -10–+10V input.
