When this bit is at 0 the precision reference parameters are read and stored in internal memory. Because the precision
reference has to be set in two parameters, this bit is provided to prevent the drive reading the parameters while the reference
is being updated. Instead, the drive uses the value stored in memory thus preventing the possibility of data skew.

Three skip frequency's available to prevent mechanical resonance's in a system by ensuring that certain frequencies are
avoided by always ramping through them. When a skip frequency parameter is set to 0 that filter is disabled.

The skip frequency band parameters define the frequency either side of the programmed skip frequency, over which
references are rejected. The actual reject band is therefore twice that programmed in these parameters, the skip frequency
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 speed is always less than demanded.
1.35
This parameter indicates that the selected reference is within one of the skip frequency regions such that the motor speed is
not as demanded.
