These function codes define the relation between
analog input voltage and corresponding set value
of analog input. When the analog input voltage
exceeds the range of max./min. input, the max.
input or min. input will be adopted during
calculation.
When analog input is current input, 0–20mA
current corresponds to 0–10V voltage.
In different applications, 100% of analog setting
corresponds to different nominal values.
The figure below illustrates several settings.
Input filter time: Adjust the sensitivity of analog
input, increase this value properly can enhance
the anti-interference capacity of analog variables;
however, it will also degrade the sensitivity of
analog input.
Note: AI1 can support 0–10V/0–20mA input, when
AI1 selects 0–20mA input; the corresponding
