Digital Filter
The digital filter is a function for reducing drifts of the indicated value by means of a moving
average of data converted from analog to digital. With an increase in the number of filterings, the
indicated value becomes more stable, but the response to inputs becomes slower.
Number of settings: OFF, 2 - 999
How to set
5-3.
Analog Filter
A low-pass filter is provided for filtering input signals from the voltage

current output device
(sensor) and canceling noise components.
The cut-off frequency can be selected in a range between 30Hz and 1000Hz. With an increase in the
cut-off frequency, the response becomes faster, but noise components may be indicated.
Cut-off frequency: 30Hz, 100Hz, 300Hz, 1000Hz

Motion Detect (MD)
Enter the parameters to detect stable.
If the difference between the current indicated value and the 50-msec-previously indicated value is
less than the set count and the duration of the condition is more than the set time, the indicated
value is regarded to be stable.
Setting range:
MD (Time): 0.0 - 9.9 sec.
MD (Count): 0 - 99 count

When the time is 0.0 sec. and the width is 00 markings, stable is not detected.
Stability detection by Motion Detect is closely related to the SI/F print (stable
value) function and comparison timing. For details, see "5-8.SI/F Print Out"on
