Fig. 5-10 Relationship between analog input and setup value
The parameters mentioned above define the relationship between analog input voltage and the analog
input setup value.
When analog input voltage exceeds the setup
“maximum input” limit, analog voltage is calculated as
“maximum input” .Similarly, when analog input is smaller than the setup “minimum input”,analog voltage is
calculated as minimum input or 0.0% according to the setting of P4.34.
AI used as current input terminal
：
1mA current equals to 0.5V voltage.
AI input filtering time is used to set AI1 software filtering time.When field anlog quantity is vulnerable,
please increase the filtering time so that anlog quantity tends to be stable. But excessive filtering time will
lead to slow response time to anlog detection. User should balance it according to practical application
cases.
In various application cases, the nominal value corresponding to 100% of analog reference will be
different. Refer to specific application description for the specific value.
