Configuring ACS550 drives 
Starting ACS550 drives for PROFIBUS DP 
1.  Power up the drive. 
2.  Enable the communication between the adapter module and the drive by setting parameter 98.02 
COMM PROT SEL to EXT FBA. 
3.  Set the RPBA-01 configuration parameters in group 51. At the minimum, set the required node 
address in parameter 51.02. 
4.  With parameter 30.18 COMM FAULT FUNC, select how the drive reacts to a fieldbus communication 
break. 
5.  With parameter 30.19 COMM FAULT TIME, define the time between communication break detection 
and the selected action. 
6.  Define the process data transferred to and from the drive in the RPBA-01 configuration parameter 
group 51.  
Note: The Status Word, Actual Speed, Control Word and Speed Reference are fixed in ACS550 and 
not necessary to set. 
7.  Validate the settings made in parameter group 51 by setting parameter 51.27 FBA PAR REFRESH to 
REFRESH. 
8.  Set the relevant drive control parameters to control the drive according to the application.
