9-3-14. AI digital filter
The digital filter calculates moving average of A/D converter outputs and reduces the
fluctuation of readings. Moving average length, or the number of data to be averaged,
can be selected from 0 (averaging OFF) to 64 (specified as the number of power to 2).
It can be specified for each channel independently.
You can obtain smoother reading as the number of averaging increases, but with slower
response. Reducing the averaging number provides quicker response, but with more
reading fluctuation.
Operation
9-3-15. Target entry select
Target can be modified by using external signals (4-20 mA, or 0-10V analog input)
on condition that:
Target = (AI target value ×(External input value %)/100)
(Cont. feed rate, Cont. total)
Target = External input value % (Fixed)
Also when the system is in slave-mode operation, target modification through external analog
inputs is available only when the operation mode is fixed.
* Inside the F805AT-BC, the sequence of operations required to update CONTROL RATE after
a target modification input will take place once in every second. The target modification input
must be locked for longer than two seconds: the system commences the sequence of
operations after confirming that the input is stable for more than two (fixed) seconds.
Three steps are required for target modification: select either Analog 1ch or Analog 2ch in
[Target entry select], specify analog input reference value in [AI Target Value], and, current
(voltage) settings in [AI zero set] and [AI full-scale set].
