148 ACH550-UH User’s Manual
Serial Communication – EFB
• Fieldbus controller supplied command(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent – the
table shows samples.)
1. Applies only for Modbus using ABB Drive profile.
2. BACnet not defined at time of publication.
3. The reference provides direction control – a negative reference provides reverse rotation.
Input Reference Select
Using the fieldbus to provide input references to the drive requires:
• Drive parameter values set 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 – the
table shows samples.)
1. Applies only for Modbus using ABB Drive profile.
2. BACnet not defined at time of publication.
Reference Scaling
Where required, REFERENCES can be scaled. See the following, as appropriate:
• Modbus Register "40002" in the "Modbus Protocol Technical Data" section.
• "Reference Scaling" in the "ABB Drives Profile Technical Data" section.
• "N2 Analog Output Objects" in the "N2 Protocol Technical Data" section.
• The slope of points 60 and 61 in the "FLN Protocol Technical Data" section.
• TBD in the "BACnet Technical Data" section.
