Example 7: Configuring the process data read from the drive
PROFIdrive parameter 916 can be used to define which data is
read cyclically from the drive as application-specific process data.
In the example below, drive parameter 1.04 (01h.04h) is selected
to be transmitted by the drive as PZD3. The selection is in force
until it is superseded by another selection.
Subindex (IND) defines which process data word the required data
is transmitted in, and Parameter Value defines which drive
parameter is mapped to that word.
