Parameter Description
3-13 Reference Site
Option: Function:
Select which reference site to activate.
[0] Linked to Use local reference when in Hand mode; or
Hand / Auto remote reference when in Auto mode.
[1] Remote Use remote reference in both Hand mode and
Auto mode.
[2] Local Use local reference in both Hand mode and
Auto mode.
NOTICE

converter starts with this setting again
following a 'power down'.
3-14 Preset Relative Reference
Range: Function:
0 % [-100 - The actual reference, X, is increased or decreased
*
100 %] 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 and
8-02 Control Source.
