310 Fieldbus control with embedded fieldbus
 Fieldbus reference scaling
Fieldbus references REF1 and REF2 are scaled for the ABB drives profile as shown
in the following table.
Note: Any correction of the reference (see section Reference selection and
correction on page 310) is applied before scaling.
Note: The settings of parameters 1104 REF1 MIN and 1107 REF2 MIN have no
effect on the reference scaling.
