Only setpoint 1 is used. The sum of setpoint 1
and any other references that are enabled (see
C-30 and C-34) are used as the PID controller's
setpoint reference.
Sets up the PID controller to calculate the
difference between feedback 1 and setpoint 1,
feedback 2 and setpoint 2, and feedback 3 and
setpoint 3. It uses the feedback/setpoint pair in
which the feedback is the farthest below its
corresponding setpoint reference. If all feedback
signals are above their corresponding setpoints,
the PID controller uses the feedback/setpoint pair
with the least difference between the 2.
