General Parameters
These parameters allow selecting the controller mode (coupled or uncoupled), the number
of channels and the sampling frequency (through the decimation factor). The main
sampling frequency must be set to 78.125 kHz to help minimize loop-back delay. Next,
the decimation factor can be used to adjust the optimization rate (or the decimated
sampling frequency). All these parameters have an impact on the maximum number of
coefficients that can be used for all controller filters. We suggest these parameters be set
first.
Orientation filter parameters (band-pass filter on error and reference signals)
The band-pass filter is applied to all error and reference signals. The parameters for this
filter can be entered directly into the configuration dialog box or through a dedicated
filter design interface (see Figure 14):
