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 .
NOTE: This is not required with MicroTech III controls .
• 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 .

Input Reference Select
Using the fieldbus to provide input reference to the drive
requires:
• Drive parameter value set as defined below.
• Fieldbus controller supplied reference word(s) in the
appropriate location. (The location is defined by the
Protocol Reference, which is protocol dependent .)
NOTE: Multiple references are supported only when using
the Daikin Drives profile.

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 .)
Description
Start/Stop controlled by fieldbus with Ext1 selected.
Start/Stop by controlled fieldbus with Ext2 selected.
Direction controlled by fieldbus.
Scaling
Where required, REFERENCES can be scaled . See the
Reference scaling in the following sections, as appropriate:
• Daikin drives profile technical data
• Generic profile technical data
