Communication Setup – FBA
Serial Communication Selection
To activate the serial communication, use parameter 9802
COMM PROTOCOL SEL. Set 9802 = 4 (EXT FBA).
Serial communication conguration
Setting 9802, together with mounting a particular FBA module,
automatically sets the appropriate default values in parameters
that dene the communication process. These parameters and
descriptions are dened in the user’s manual supplied with the
FBA module.
NOTE: This is not required with MicroTech III controls.
• Parameter 5101 is automatically congured.
• Parameters 5102…5126 are protocol-dependent and
dene, for example, the prole used, and additional
I/O words. These parameters are referred to as the
eldbus conguration parameters. See the user’s manual
provided with the FBA module for details on the eldbus
conguration 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
conguration to:
• Tell the drive to accept eldbus control of the function.
• Dene as a eldbus input, any drive data required for
control.
• Dene as a eldbus output, any control data required by
the drive.
The following sections describe, at a general level, the
conguration 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 eldbus for start/stop/direction control of the drive
requires:
• Drive parameter values set as dened below.
• Fieldbus controller supplied command(s) in the
appropriate location. (The location is dened by the
Protocol Reference, which is protocol dependent.)
Table 45: Start/Stop/Direction Control
Drive Parameter Value Description Protocol Reference
1001 EXT1 COMMANDS 10 (COMM) Start/Stop controlled by eldbus with Ext1 selected.
1002 EXT2 COMMANDS 10 (COMM) Start/Stop by controlled eldbus with Ext2 selected.
1003 DIRECTION 3 (REQUEST) Direction controlled by eldbus.
Input Reference Select
Using the eldbus to provide input reference to the drive
requires:
• Drive parameter value set as dened below.
• Fieldbus controller supplied reference word(s) in the
appropriate location. (The location is dened by the
Protocol Reference, which is protocol dependent.)
NOTE: Multiple references are supported only when using
the Daikin Drives prole.
Scaling
Where required, REFERENCES can be scaled. See the
Reference scaling in the following sections, as appropriate:
• Daikin drives prole technical data
• Generic prole technical data
Table 46: Input Reference
Drive Parameter Value Description Protocol Reference
1102 EXT1/EXT2 SEL 8 (COMM) Ref. selected by eldbus. (Required only if 2 references used.)
1103 REF1 SEL
8 (COMM)
9 (COMM+AI1)
10 (COMM*AI1)
Input reference 1 supplied by eldbus.
1106 REF2 SEL
8 (COMM)
9 (COMM+AI)
10 (COMM*AI)
Input reference 1 supplied by eldbus. (Required only if 2 references
used.)
