Appendix A – Fieldbus control
What this chapter contains
The chapter describes how the drive can be controlled by external devices over a
communication network (fieldbus) through an optional fieldbus adapter module.
System overview
The drive can be connected to an external control system via a fieldbus adapter
module. The adapter module is installed into drive Slot 3.
The drive can be set to receive all of its control information through the fieldbus
interface, or the control can be distributed between the fieldbus interface and other
available sources, for example, digital and analogue inputs.
Fieldbus adapters are available for various serial communication protocols, for
example:
• PROFIBUS DP (FPBA-xx adapter)
• CANopen (FCAN-xx adapter)
• DeviceNet™ (FDNA-xx adapter)
• Modbus/RTU (FSCA-xx adapter)
• Modbus/TCP, EtherNet/IP™, PROFINET IO (FENA-xx adapter)
