3-13 Reference Site
Option: Function:
Select which reference site to activate.
[0] * Linked to
Hand / Auto
Use local reference when in Hand mode; or
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.

When set to [2] Local, the frequency
converter will start with this setting
again following a 'power down'.
3-14 Preset Relative Reference
Range: Function:
0.00
%*
[-100.00 -
100.00 %]
The actual reference, X, is increased or
decreased with the percentage Y, set in
3-14 Preset Relative Reference. This results
in the actual reference Z. Actual reference
(X) is the sum of the inputs selected in
3-15 Reference 1 Source, 3-16 Reference 2
Source, 3-17 Reference 3 Source and
8-02 Control Source.

3-15 Reference Resource 1
Option: 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
