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 mounted onto the control unit of the drive. The drive actually has two
independent interfaces for fieldbus connection, called "fieldbus adapter A" (FBA A)
and "fieldbus adapter B" (FBA B). The drive can be configured to receive all of its
control information through the fieldbus interface(s), or the control can be distributed
between the fieldbus interface(s) and other available sources such as digital and
analog inputs, depending on how control locations EXT1 and EXT2 are configured.
Note: It is recommended that the FBA B interface is only used for monitoring.
Fieldbus adapters are available for various communication systems and protocols, for
example
• PROFIBUS DP (FPBA-01 adapter)
• CANopen (FCAN-01 adapter)
• DeviceNet (FDNA-01 adapter)
• EtherNet/IP (FENA-11 adapter)
TM
• EtherCAT ® (FECA-01 adapter).
