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.
NOTE
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 %* [-100 -
100
%]
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 1 Source
Option: Function:
Select the reference input to be used
for
the first reference signal.
3-15 Reference 1 Source, 3-16 Reference
2 Source and 3-17 Reference 3 Source
define up to three different reference
signals. The sum of these reference
signals defines the actual reference.

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