Embedded Fieldbus
Embedded Fieldbus
Overview
The ACS510 can be set up to accept control from an external system using standard
serial communication protocols. When using serial communication, the ACS510 can
either:
• Receive all of its control information from the fieldbus, or
• Be controlled from some combination of fieldbus control and other available
control locations, such as digital or analog inputs, and the control panel.
Two basic serial communications configurations are available:
• Embedded fieldbus (EFB) – Using the RS485 interface at terminals X1:28…32 on
the control board, a control system can communicate with the drive using the
Modbus® protocol. (For protocol and profile descriptions, see "Modbus Protocol
Technical Data" and "ABB Control Profiles Technical Data" later in this section.)
• Fieldbus adapter (FBA) – See "Fieldbus Adapter" on page 175.

• Output words
– Control Word
– Reference1
– Reference2
• Input words
