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.
NOTICE
When set to [2] Local, the frequency
converter starts 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.

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
3 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
3 different reference signals. The sum
of these reference signals defines the
actual reference.
