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.
