9. Parameter Numbering
Inspection of the Toshiba ASD user’s manual reveals that the ASD’s
parameters are organized as hexadecimal numbers ranging from F000 to
FFFF. These parameters are made accessible to the interface board as
“registers”, and are numerically remapped to present a more natural interface to
the communications user. There are 1500 total registers available via the
interface board, and their mappings are as shown in Table 1.

This mapping is easier to understand if one just uses the interface's web page
as a guide (refer to Figure 6 and section 10.4.4). The "parameter” numbers
(ASD references) and "register” numbers (network references) for all available
parameters are shown in the first two columns. Commanding the drive over the
network therefore entails writing to registers 1007 (option board command) and
1008 (option board frequency command), which correspond to ASD parameters
FA06 and FA07, respectively.

To avoid confusion, when this user’s manual uses the term “parameter”, it will
be referring to the ASD’s hexadecimal number as documented in the ASD
