The actual reference, X, is increased or decreased
with the percentage Y, set in parameter 3-14 Preset
Relative Reference.
This results in the actual reference Z. Actual
reference (X) is the sum of the inputs selected in:
•
Parameter 3-15 Reference 1 Source.
•
Parameter 3-16 Reference 2 Source.
•
Parameter 3-17 Reference 3 Source.
•
