Fieldbus reference scaling
Fieldbus references REF1 and REF2 are scaled as shown in the following tables.
Note:
Any correction of the reference (see section
on page
) is applied before scaling.
Fieldbus scaling for ABB Drives profile
Note:
REF1 MIN and
REF2 MIN have no
effect on the reference scaling.
Fieldbus scaling for DCU profile
Note:
REF1 MIN and
REF2 MIN have no
effect on the reference scaling.
