Function:
Select the reference input to be used
for the first reference signal.
3-15 Reference Resource 1,
3-16 Reference Resource 2 and
3-17 Reference Resource 3 define up to
three different reference signals. The
sum of these reference signals
defines the actual reference.
Function:
Select the reference input to be
used for the second reference
signal. 3-15 Reference Resource 1,
3-16 Reference Resource 2 and
3-17 Reference Resource 3 define up
to three different reference signals.
The sum of these reference signals
defines the actual reference.

Function:
Select the reference input to be
used for the third reference signal.
3-15 Reference Resource 1,
3-16 Reference Resource 2 and
3-17 Reference Resource 3 define up
to three different reference signals.
The sum of these reference signals
defines the actual reference.
Function:
Select a variable value to be added to the
fixed value (defined in 3-14 Preset Relative
Reference). The sum of the fixed and
variable values (labeled Y in the figure
below) is multiplied by the actual reference
(labeled X in the figure below). The result
is then added to the actual reference (X
+X*Y/100) to give the resulting actual
reference.
