*
The maximum scale length is determined by the readhead resolution and the number of position bits
in the serial word. For RESOLUTE FS with BiSS Safety readheads with fine resolution and short word
length, the maximum scale length will be limited accordingly. Conversely, coaser resolutions or longer
word lengths enable the use of longer scale lengths.
