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: The text and examples in this chapter describe the configuration of one fieldbus
adapter (FBA A) by parameters 50.01...50.21 and parameter groups 51...53. The second
adapter (FBA B), if present, is configured in a similar fashion by parameters 50.31...50.51
and parameter groups 54...56. 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
