Remote controlled references are defined as:
- External references, such as analog inputs 53
and 60, pulse references via terminal 33 and
references from serial communication.
- Preset references.
The resulting reference can be shown on the LCP
control unit's display by selecting Reference [%] in
parameters 009-012 Display readout and can be
shown as one unit by selecting Reference [unit].
The sum of the external references can be shown on
the LCP control unit's display as a % of the area from

Reference function a selection can be made
to determine how preset references should be
added to the external references.
There is also an independent local reference in
parameter 003 Local reference, in which the
resulting reference is set using the [+/-] keys.
When the local reference has been selected, the
output frequency range is limited by parameter 201
