7−5. Stabilized filter
The instrument prepares the Stabilized filter that can filter through digital filter strongly when
variable width for load is within the constant value and also the same condition is frozen for more
than a constant period.
7−5−1. What is the Stabilized filter?
When the variable width of load is within the set value by the function F−17 and also the same
condition is frozen for more than the set value with the F−16, the digital filter for stabilized
filter will become effective set with the function F−15. That is, the digital filter will be applied
only when the load is stable for more than a constant value, and then stabilizes the load display.
7−5−2. Setting related with the Stabilized filter.
D Set the data to apply the Stabilized filter with the function F−17. The stabilized filter
width per set value “n” can be obtained through the display conversion by using the
following formula.
[Stabilized filter data width]＝[Set value of F−17]×[Display increment value]
For example, when the setting of function F−17 is “00010” and the display increment is
“D=5”, then
[Stabilized filter data width]＝10×5
＝50
D Data width supervisory time for the Stabilized filter can be set with the function F−16.
D The digital filter for Stabilized filter can be set with the function F−15.
D The averaged−out times for the digital filter for Stabilized filter per set value “m” can be
obtained by the following formula.
[Stabilized filter averaged−out times]＝2
m
For example, when the setting of function F−15 is “00002”,
[Stabilized filter times]＝2
2
＝4(Times)
D Moreover, when the digital filter has set with the function F−04, the averaged−out times
will be “Stabilized filter averaged−out times” and “Averaged−out times” with the function
F−04. (Refer to the paragraph 7−3.)
That is,
[Averaged−out times]
＝[Averaged−out times with the F−04]×[Averaged−out times of stabilized filter]
For example, setting for the function F−04 is “00004” and the function F−15 is “00002”
as well, it will be as follows:
[Averaged−out times]＝2
4
×2
2
＝16×4
＝64(times)
