Example 2: Writing a drive parameter (or data set)
To determine the parameter number and subindex for drive
parameter writing, convert the drive parameter group number and
the parameter index number to hexadecimal. The index number is
the
Subindex
(IND), and the group number is the
Parameter
Number
(PNU). For example, to write parameter
12.02
to the drive:
12.02
= 0Ch.02h => Parameter number = 0Ch, Subindex = 02h.
The following is an example of writing a 16-bit parameter.
