When the analog input voltage exceeds the maximum value (P3.18), the maximum value is
used. When the analog input voltage is less than the minimum value (P8.16), the value set
in P3.36 (Setting for AI less than minimum input) is used.
When the analog input is current input, 1 mA current corresponds to 0.5 V voltage.
P3.20 (VI1 filter time) is used to set the software filter time of VI1. If the analog input is liable
to interference, increase the value of this parameter to stabilize the detected analog input.
However, increase of the VI filter time will slow the response of analog detection. Set this
parameter properly based on actual conditions.
In different applications, 100% of analog input corresponds to different nominal values. For
details, refer to the description of different applications.
Two typical setting examples are shown in the following figure
