9.3.1.1.4. Assembly instance 25 – extended process control output
The extended process control assembly can be used to
send process reference value directly to the application.
The Process Reference value destination can be selected
with the Drive Mode byte according to the table below.
This should be configured in the application as the receiving
input. To the other direction (input assembly instance 75),
the ProcessDataOut1 is always mapped to the Process
Actual. Note that the process reference value is sent to the
drive only when NetProc bit is set.
The Eaton drives do not support the actual “Process
Control”-mode. Therefore the Drive Mode cannot be set
to the Process Control by using the AC/DC Drive Object
attribute, and the Drive Mode parameter in this assembly
is only used to select the process reference. With these
mappings, the Process Reference and Process Actual can
be used with an application that supports the PID control.
