Fieldbus control through a
fieldbus adapter
What this chapter contains
This chapter describes how the drive can be controlled by external devices over
a communication network (fieldbus) through an optional fieldbus adapter
module.
The fieldbus control interface of the drive is described first, followed by a
configuration example.
System overview
The drive can be connected to an external control system through an optional
fieldbus adapter (“fieldbus adapter A” = FBA A) mounted onto the control unit
of the drive. The drive can be configured 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 such as digital and analog inputs,
depending on how control locations EXT1 and EXT2 are configured.
Fieldbus adapters are available for various communication systems and
protocols, for example
• Profibus (FPBA-01 adapter)
• CANopen (FCAN-01 adapter)
• Ethercat (FECA adapter)
• Ethernet IP

/Profinet/Modbus TCP(FENA-11/21 adapter)
• ModbusRTU (FSCA) (applicable only for R3...R8 frames)
