Speed filter time

Description

The parameter is displayed when was set in the Encoder type parameter.

Time interval for determining the average speed. For the EI7C FS encoder, the average speed is determined over the last 4 encoder increments recorded.

The filter time is used to compensate for physical fluctuations in the speed.

The filter time has an impact on the response time of the speed functions (safety sub-functions SSx, SLS, SSM, SSR) and must be taken into account in the safety assessment.

The default value of the filter time is 0 ms.

For an EI7C FS encoder, SEW‑EURODRIVE recommends setting the filter time to 0 ms.
