ACH580 E-Clipse bypass and packaged drive user manual 165
Fieldbus adapter
Communication setup – FBA
Protocol selection
To activate the fieldbus adapter 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 5201…5210 provide parameter mapping data from E-Clipse Bypass
to field controller.
• Parameters
5301…5310 provide parameter mapping data from fieldbus controller
to E-Clipse Bypass.
• To map ACH580 parameters in groups 52 or 53 program parameters 5201…5210
or 5301…5310 with the actual ACH580 parameter value in hexadecimal. For
example: to read ACH580 parameter 2897 (Frequency ref unlimited) convert
group 28 to hexadecimal and parameter 97 to hexadecimal and combine as
follows:
28 = 1ch
97 = 61h
parameter 52.01 is set to:
1c61h
• To map E-Clipse Bypass parameters in groups 52 or 53 program parameters
5201…5210 or 5301…5310 add 8000h to the calculation:
Bypass parameter 0106 (KW HOURS):
01 = 01h
06 = 06h
parameter 5201 is set to:
0106h + 8000h = 8106h
The Parameters section lists the group 51 parameters.
