System overview
The drive can be connected to an external control system,
usually a fieldbus controller, either:
• via a plug-in fieldbus adapter (EXT FBA) module mounted in
expansion slot 2 of the drive. EXT FBAs must be ordered
separately. EXT FBAs include:
- PROFIBUS DP
- INTERBUS
- LonWorks
- CANopen
- DeviceNet
- Modbus Plus
- ControlNet
- Ethernet
or
• via the standard RS485 interface at terminals X1:28...32 on
the control board of the drive. The standard RS485 interface
provides the following embedded fieldbus (EFB) protocols:
- Modbus
- Metasys N2
- FLN
- BACnet.
For more information, refer to the Embedded Fieldbus (EFB)
Control Manual [3AFE68320658 (English)].
Both the plug-in fieldbus adapter (EXT FBA) module and the
embedded fieldbus (EFB) protocol are activated by means of
parameter 9802
