Input Set Selection
Unit’s digit: AI1 is lower than min input
setting selection
0: Corresponding to the min input set
1: 0.0%
Ten’s digit: AI2 is lower than min input
setting selection, same as above
Hundred’s digit: AI3 is lower than min
input setting selection, same as above

The function code is used for setting, when the voltage of the analog input is smaller than the
“minimum input” set, how to determine the setting of analog corresponds.
The unit’s digit and ten’s digit of function code are corresponding analog input AI1, AI2 and AI3
(expansion card) respectively.
If selection is 0, when the AI input is lower than the “minimum input”, then the analog corresponding
setting for “minimum input corresponding setting” of function code to determine the curve (F5-22,
F5-27, F5-32).
If selection is 1, when the AI input is lower than the minimum input, then the analog corresponding
setting is set to 0.0%.

The above function code is used to set the relationship between the analog input voltage and the
setting value of the representative.
When the analog input voltage is greater than the set “maximum input” (F5-24), the analog voltage is
caculated according to the “Maximum input”; similarly, when the analog input voltage is less than the
set “maximum input” (F5-22), depending on the “AI is lower than the minmum input set selection”
(F5-21) settings, with the minimum input or 0.0% calculation.
When analog input for the current input, 1mA current equivalent to a 0.5V voltage.
AI1 input filter time, used to set AI1 software filter time, when the on-site analog is easily effected,
then increase filter time to make detecting analog signal getting steady. But the filter time is bigger,
the analog signal detecting response speed is lower. Please consider the actual situation to set.
In different application, analog set 100.0% is different from its corresponding nominal value, please
refer to application description. Fig 6-15 is two typical setting situation:
