ABB ACH550-VCR User Manual

ACH550-UH User’s Manual 1-263
Fieldbus adapter
Communication setup – FBA
Serial communication selection
To activate the serial communication, use parameter 9802
COMM PROTOCOL SEL. Set
9802 = 4 (
EXT FBA).
Serial communication configuration
Setting 9802, together with mounting a particular FBA module, automatically sets the
appropriate default values in parameters that define the communication process.
These parameters and descriptions are defined in the user’s manual supplied with
the FBA module.
• Parameter 5101 is automatically configured.
• Parameters 5102…5126 are protocol-dependent and define, for example, the
profile used, and additional I/O words. These parameters are referred to as the
fieldbus configuration parameters. See the user’s manual provided with the FBA
module for details on the fieldbus configuration parameters.
• Parameter 5127 forces the validation of changes to parameters 5102…5126. If
parameter 5127 is not used, changes to parameters 5102…5126 take affect only
after the drive power is cycled.
• Parameters 5128…5133 provide data about the FBA module currently installed
(e.g. component versions and status).
The Parameters section lists the group 51 parameters.
Activate drive control functions – FBA
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. The last column in each table below is deliberately blank. See
the user’s manual supplied with the FBA module for the appropriate entry.
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.)
