Setting Up The Dc/Dc Converter For Fieldbus Control - ABB ACS880 Firmware Manual

198 Fieldbus control through a fieldbus adapter

Setting up the DC/DC converter for fieldbus control

Before configuring the DC/DC converter unit for fieldbus control, the adapter module must
be mechanically and electrically installed according to the instructions given in the User's
manual of the appropriate fieldbus adapter module.
Note: To be able to switch the DC/DC converter unit on and off (Run enable signal)
through the fieldbus, the Run enable command at the digital input must be on (1). That is
the case when the operating switch is switched to the on (1) position.
1. Power up the DC/DC converter unit.
2. Enable the communication between the DC/DC converter unit and the fieldbus
adapter module by setting parameter

Note: This function monitors both the communication between the fieldbus master
and the adapter module and the communication between the adapter module and the
DC/DC converter unit.

5. Select application-specific values for the rest of the parameters in group
6. Set the fieldbus adapter module configuration parameters in group
settings. At the minimum, set the required node address and the communication
profile. Set profile to transparent 16 mode.
Note: The parameter indexes and names vary as the way the different fieldbus
adapters use these parameters.
Example: For the FPBA-xx adapter, set parameter 51.05 Profile to mode Trans16.
7. Define the process data transferred to and from the DC/DC converter unit in
parameter groups
Note: The adapter module sets the Status word and Control word automatically into
parameters 152.01
8. Save the valid parameter values to permanent memory by setting parameter
Param save to Save.
9. Validate the settings made in parameter groups 151, 152 and 153 by setting
parameter 151.27 FBA par refresh
10. Select the fieldbus adapter A as the source of the start and stop commands for
external control location EXT1 by setting parameter
Fieldbus A.
Set the relevant control parameters to control the DC/DC converter unit according to the
