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.
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 supports 0 – 10V input and AI2
supports 0 – 10V or 0 – 20mA input, when AI2
selects 0 – 20mA input, the corresponding voltage
of 20mA is 10V. AI3 can support the output of
-10V – +10V (up to 2.2kW).
AI1 can support 0-10V/0-20mA input, when AI1
selects 20mA input, the corresponding voltage of
20mA is 10V; AI2 supports -10V-+10V input (from
4kW and higher).
