Quickstart Guide
ABB PLC and drives integration using Modbus RTU
Drive configuration
Drives without embedded Modbus RTU need to be equipped with Modbus RTU adapter according to actual drive
type.
The following drive configuration steps will adapt the drive to Modbus RTU control based on ABB‐specific drives
library PS553‐DRIVES.
Drive parameters can be set from the drive's control panel or from drive‐specific pc tool (DriveWindow Light for
ACS355 and ACS550, DriveStudio for ACS850 and ACSM1, Drive Composer for ACS880 and DriveWindow for
ACS800).
Note! All parameter settings are based on drive default settings. If the drive has been parameterized previously,
return to default settings before continuing. It can be done by:
Changing macro (and then changing back again) in parameter 99.02 for ACS310, ACS355 and ACS550.
Setting parameter 99.03 APPLIC RESTORE to YES in ACS800.
Setting parameter 16.04 Param restore to Restore defs in ACS850 and ACSM1.
Setting parameter 96.06 Parameter restore to Restore defaults in ACS880.
