Embedded fieldbus
Activate drive control functions – EFB
Controlling the drive
Fieldbus control of various drive functions requires configuration to:
tell the drive to accept fieldbus control of the function
define as a fieldbus input, any drive data required for control
define as a fieldbus output, any control data required by the drive.
The following sections describe, at a general level, the configuration required for
each control function. For the protocol-specific details, see the document supplied
with the FBA module.
Start/Stop Direction control
Using the fieldbus for start/stop/direction control of the drive requires:
drive parameter values set as defined below
fieldbus controller supplied command(s) in the appropriate location. (The location
is defined by the Protocol Reference, which is protocol dependent.)

For Modbus, the protocol reference can depend on the profile used, hence two columns in these
tables. One column refers to the ABB Drives profile, selected when parameter 5305 = 0 (
ABB DRV
LIM) or 5305 = 2 (ABB DRV FULL). The other column refers to the DCU profile selected when
parameter 5305 = 1 (
DCU PROFILE). See section ABB control profiles technical data on page 219.

The reference provides direction control – a negative reference provides reverse rotation.
