Measured value filter

Each measuring axis has an integrated digital filter. You can enable and configure the filter individually for each measuring axis.

Measured value filter 1:

Recommendation: use "Filter Designer"

Use the TE1310 | "TwinCAT 3 Filter Designer" for a simplified configuration of the filters, see https://www.beckhoff.com/te1310.

Manual configuration

If you do not use the "TwinCAT 3 Filter Designer", you must configure the filters manually using CoE parameters. This is particularly recommended for simple predefined filters.

Set the type of filter in the CoE parameter "Filter Settings" of the respective measuring axis:
