The on-going servo and commutation position data is setup using a 2-line Entry in the Encoder
Conversion Table. The first line represents a Parallel Y-Word with no filtering ($2) from the
corresponding Yaskawa data register/channel. The second line represents the width of the data to be read
and bit location of the LSB of the data in the source word.
