Overview

ABB Drives profile

The ABB Drives profile provides a standard profile that can be used on multiple
protocols, including Modbus and the protocols available on the FBA module. Two
implementations of the ABB Drives profile are available:
•
ABB DRV FULL
ACS600 and ACS800 drives.
•
ABB DRV LIM
ACS400 drives. This implementation does not support two control word bits
supported by
Except as noted, the following "ABB Drives Profile" descriptions apply to both
implementations.

DCU profile

The DCU profile extends the control and status interface to 32 bits. It is the internal
interface between the main drive application and the embedded fieldbus
environment.
