ABB ACS550 - Analog Output Control; Relay Output Control

ACS550 User’s Manual 195
Embedded fieldbus
Relay output control
Using the fieldbus for relay output control requires:
• drive parameter values set as defined below
• fieldbus controller supplied, binary coded, relay command(s) in the appropriate
location. (The location is defined by the Protocol Reference, which is protocol
dependent.)
Note: Relay status feedback occurs without configuration as defined below.
Analog output control
Using the fieldbus for analog output control (e.g. PID setpoint) requires:
• drive parameter values set as defined below
• fieldbus controller supplied analog value(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
