14 ACH550 BACnet User’s Manual
Start-up
Relay Output Control
Using the fieldbus for relay output control requires:
Drive parameter values set as defined below.
Only make these drive programming changes if you require control via BACnet.
Fieldbus controller supplied, binary coded, relay command(s) in the appropriate
location.
1. More than 3 relays requires the addition of a relay extension module.
Analog Output Control
Using the fieldbus for analog output control requires:
Drive parameter values set as defined below.
Fieldbus controller supplied analog value(s) in the appropriate location.
Communication Fault
When using fieldbus control, specify the drive’s action if serial communication is lost.
