FB#.POSLOWPASS

Description

FB#.POSLOWPASS configures an averaging filter that is run inside the feedback device at a high data rate. This is used to lower measured position noise and help prevent aliasing from the feedback sampling rate to the drive.

 


  • Currently only SFD-M supports this feature. FB#.POSLOWPASS is only implemented when FB#.SELECT = 47 (SFD-M). It is ignored for other values of FB#.SELECT.

The following table lists the supported filter values.
