SPEED FBK FILTER
A simple filter function that is applied to Speed Feedback to reduce ripple caused by encoders with
low line count. A value of 0 diables the filter action. 1.00 is the maximum value. A typical value
would be between 0.5 and 0.75.
Increasing the filter value may make the speed loop unstable.
The filter time constant “τ” in milliseconds is calculated as follows:
