In the previous table, the number of decimal digits is shown as a decimal
number. For example, if three decimal digits are specified in the BTW
data file (word 2 = 03xx hex) and the value of the item to be sent to the
motion controller is 1572, the value 1,572,000 (1572 x 1000) must be
stored in the data file. Specifically, since 1,572,000 decimal is 17FCA0
hex, 0017 is stored in the lower numbered word of the word pair (the most
significant word), and FCA0 in the higher numbered word (the least
significant word).
