Access the servo parameters with the OD 2XXXh group. The parameter number and index are converted as follows:
Read the index first to get the information of the parameter length, and then use SDO or PDO to change the data.
Example 1:

Pa.bcd <= = > 2aBCh ‘BC’ is hexadecimal format of ‘bcd’

2511h
a = 5
BC (11h) = 17
