The equivalent 8-bit is used to display the status (used or not used) of each digital output. The
value that Pr.03.09 displays is the result after converting 8-bit binary into decimal value.
For standard AC motor drive, it only has 2-bit (bit0 and bit1). When extension card is installed,
the number of the digital output terminals will increase according to the extension card. The
maximum number of the digital output terminals is shown as follows.
