Example 2a: Writing a drive parameter (one array element)
Drive parameters are addressed so that the drive parameter group corresponds to the
Parameter index (PNU), and the drive parameter number within that group corresponds to
the Subindex (IND). In the following example, a value is written to drive parameter 12.02
(0C.02h).
