Movement
averaging
processing
selection
• When "movement averaging processing" is set in the movement
averaging processing selection, movement averaging processing
is performed on the "sampling pulse number" of the buffer
memory by the number of times set in the "number of movement
averaging processing" of the buffer memory.
• When the setting value is other than 0 or 1, a movement
averaging setting range outside error (error code: 300) occurs.
To clear the error, turn ON the error reset request (Y8 to YF) of
the corresponding channel. After this, set a correct value and
then turn ON the operating condition setting request flag (Y1).

Number of
movement
averaging
processing
• Set the number of times to perform movement averaging
processing on the "sampling pulse number" of the buffer
memory.
• When "movement averaging processing" is selected in the
"movement averaging processing selection" of the buffer
memory, the initial value of this buffer memory is "0". Therefore,
if you run the programmable controller CPU without setting the
value, a movement averaging setting range outside error (error
code: 300) will occur.
• If the setting value is outside the range, a movement averaging
setting range outside error (error code: 300) occurs. To clear the
error, turn ON the error reset request (Y8 to YF) of the
corresponding channel. After this, set a correct value and then
turn ON the operating condition setting request flag (Y1).

• The pre-scale function converts the input pulse number per count
cycle into the unit pulse number when the weight per pulse is a
fraction, and stores the result of conversion into the "sampling
pulse number" of the buffer memory. The following operation
formula is used at this time.
Sampling pulse number =
Input pulse value per count cycle
pre-scale setting value
unit magnification
The converted sampling pulse number is rounded down to the
decimal point.

If the setting value is other than the above values, a pre-scale
setting range outside error (error code: 400) occurs. To clear the
error, turn ON the error reset request (Y8 to YF) of the
corresponding channel. After this, set a correct value and then
turn ON the operating condition setting request flag (Y1).
