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.
