Above function codes define the relationship between analog input voltage and the setting
value that analog input is corresponding to. When the analog input voltage exceeds the range
of the set maximum or minimum input, the beyond portion should be calculated with maximum
input or minimum input.
When analog input is amperage input, 0mA-20mA is corresponding to 0V-10V.
For different applications, the corresponding nominal value of analog setting 100.0% is
different. For details, please refer to each application description.
Following figures shows several settings. Note: AI1 lower limit must be less or equal to AI1
upper limit.
Figure 6-12 Relationship between analog input and setting value
AI1 input filtering time determines analog input sensitiveness. Increasing this parameter, in
order to prevent malfunction caused by interference to the analog, can strengthen the
anti-interference ability, but reduce the analog input sensitiveness.
