Function:
Select which reference site to activate.
Use local reference when in Hand mode; or
remote reference when in Auto mode.
Use remote reference in both Hand mode and
Auto mode.
Use local reference in both Hand mode and
Auto mode.
NOTE
When set to Local [2], the frequency
converter will start with this setting again
following a 'power down'.
Function:
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.

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.
