** Feedback Processing
Each Feedback device has an FIR filter with the number of taps adjustable . Default
setting for each FIR filter is 8 taps. Increasing the number of taps increases the
filtering of the Speed feedback signal . Reducing the number of taps reduces the
filtering of the Speed feedback signal. See parameter descriptions for the following .
