Reference scaling
Where required, REFERENCES can be scaled. See the following, as appropriate:
• Modbus Register 40002 in the
section.
• N2 analog output objects – Drive
section.
• The slope of points 60 and 61 in the
section.
The following table describes REFERENCE scaling for the ABB Drives profile.
