motor current and voltage signals, or automatically switch to a scaled version of a
redundant feedback device. In the case of redundant feedback, Feedback 1 is called
the primary feedback source and the redundant channel is the called the secondary
feedback source.

The Feedback n Velocity Filter Taps attribute determines the number of delay
taps used in the FIR Filter differencing algorithm to estimate velocity from
Feedback n. A simple difference of 1 sample period is equivalent to a 1 delay tap.

Delay Taps (>= 1)
The Feedback n Accel Filter Taps attribute determines the number of delay taps
used in the FIR Filter differencing algorithm to estimate acceleration from
Feedback n. The Acceleration FIR filter can be implemented as two cascaded FIR
filters each configured according to the Feedback n Acceleration Filter Tap
setting. A simple difference of 1 sample period is equivalent to 1 delay tap.
