86 ACH580 E-Clipse bypass and packaged drive user manual
Embedded fieldbus
Input reference select
Using the fieldbus to provide input references to the drive requires:
• Drive parameter values set with the drive keypad as defined below.
• Fieldbus controller supplied reference word(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
EFB Ref1/Ref2
Reference
As described earlier in Control interface, the REFERENCE word is a speed or
frequency reference.
Reference scaling
Where required, REFERENCES can be scaled. See the following, as appropriate:
• Modbus Register 40002 in the Modbus protocol technical data – Drive only
section.
• N2 analog output objects – Drive in the N2 protocol technical data – system
section.
• The slope of points 60 and 61 in the BACnet protocol technical data – system
section.
The following table describes REFERENCE scaling for the ABB Drives profile.
