The above function code is used to set the relationship between the analog input
voltage and the set value it represents.
When the analog input voltage is greater than the set maximum input (P4-15), the
analog voltage is calculated as the maximum input; when the analog input voltage is
less than the set minimum input (P4-13), then P4 The -34 setting is calculated with a
minimum input or 0.0%.
When the analog input is a current input, the 1mA current is equivalent to 0.5V.
AI1 input filtering time is used to set the software filtering time of AI1. When the field
analog quantity is easily disturbed, please increase the filtering time so that the
detected analog quantity tends to be stable, but the larger the filtering time is, the
analog quantity detection is. The slower the response.
In different applications, the nominal value corresponding to 100.0% of the analog
setting is different. For details, please refer to the description of each part. The
following illustrations are for two typical settings:
