Subsequently, the contents of PZD3 in each Request frame are written to drive parameter
12.06 until a different selection is made.
Example 5: Determining the source of the process data read from the drive
PROFIdrive parameter 916 (394h) can be used to define which data is read cyclically from
the drive as application-specific process data. In the example below, the parameter is used
to determine which drive parameter the contents of PZD3 are taken from. Subindex (IND)
defines which process data word the required data is transmitted in.
