ACH550 E-Clipse Bypass User’s Manual 2-203
Fieldbus adapter
Communication setup – FBA
Protocol selection
To activate the serial communication, use parameter 9802
COMM PROTOCOL SEL. Set
bypass parameter 9802 = 4 (
EXT FBA).
Protocol 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).
• Parameters 5401…5410 provide parameter mapping data from E-Clipse Bypass
to field controller.
• Parameters 5501…5510 provide parameter mapping data from fieldbus controller
to E-Clipse Bypass.
• To map ACH550 parameters in groups 54 or 55 program parameters 5401…5410
or 5501…5510 with the actual ACH550 parameter value. For example to read
ACH550 parameter 0106 (Power), program parameter 5401 to 0106.
• To map E-Clipse Bypass parameters in groups 54 or 55 program parameters
5401…5410 or 5501…5510 add 10,000 to the E-Clipse Bypass parameter value.
For example to read E-Clipse Bypass parameter 0106 (KW Hours), program
parameter 5401 to 10106.
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 (via the bypass) 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.
