Reference scaling. The scaling of the fieldbus references REF1
and REF2 is indicated in the table below.
Reference Range
REF1 -32767...
+32767
REF2 -32767...
+32767
Note:The setting of parameter 1104 REF1 MIN and 1107 REF2
MIN has no effect on the scaling of the references.
The value 20000 in case of REF1 and the value 10000 in case
of REF2 correspond to a reference value of 100% (see section
Reference handling below).
