5 DETAILS AND SETTING OF FUNCTIONS
5.7 Movement Averaging Function
The movement averaging function averages the values of the sampling pulse
number, which were imported in the count cycle (refer to Section 5.1.4), by the
specified number of times to calculate the average value. This function is used
when variations occur in the values of the sampling pulse number.
The following shows the outline of movement averaging function operation.
Movement averaging processing performed when the setting number is four
times.

Sampling pulse
number
*: From a counter reset or immediately after an operating condition setting request until
reaching the number of movement averaging processing, averaging processing is
performed by that number.

POINT
• If the setting value is other than the above values, 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 settings are reflected on the module by turning ON the operating condition
setting request flag (Y1) after setting the values to the buffer memory.
