non-volatile storage unit, as for these parameters, function codes 0x41 and 0x06 have
the same operation effects, and these parameters will be introduced in the following.
The management of drive function codes includes reading upper limit and lower
limit of parameters, reading parameter characteristics, reading function code menu’s
max. group index, reading the next function code group number and the previous
function code group number, reading the current display state parameter index as well
as displaying the next state parameter etc. Parameter characteristics include
information such as parameter readability and writability, parameter unit as well as
scaling relation etc. These commands are used to remotely modify drive function code
parameters. Application layer protocol data units managed by function codes are as
follows:
Request format is as follows:

Detailed range should be
decided according to the drive’s
type.
