Example 6: Configuring the process data written to the drive
PROFIBUS parameter 915 can be used to define which data is
written cyclically to a drive parameter as application-specific
process data.
In the example below, the value of drive parameter
12.02 CONSTANT SPEED 1 (4B2h) is selected to be taken from
PZD3. The parameter will continue to be updated with the
contents of PZD3 in each Request frame until a different selection
is made.
Subindex (IND) defines which process data word the required
data is taken from. Parameter Value selects the drive parameter to
which that word is mapped.
Subsequently, the contents of PZD3 in each Request frame are
written to drive parameter 12.02 CONSTANT SPEED 1 until a
different selection is made.
