Reference scaling. The scaling of the fieldbus references REF1
and REF2 is shown in the table below.
Reference Range
REF1 -32767...
+32767
REF2 -32767...
+32767
Note: The setting of parameter 1104
has no effect on the scaling of the references.
MIN
The value 20000 in case of REF1 and the value 10000 in case
of REF2 correspond to a reference value of 100% (see
Reference handling on page 158).
