Three skip references are available to prevent continuous operation at a speed that would cause mechanical resonance. When a skip reference
parameter is set to 0 that filter is disabled. The skip reference band parameters define the speed range either side of the programmed skip reference,
over which references are rejected. The actual reject band is therefore twice that programmed in these parameters, the skip reference parameters
defining the centre of the band. When the selected reference is within a band the lower limit of the band is passed through to the ramps such that
reference is always less than demanded.
