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 (
