Fieldbus control
Chapter overview
The chapter describes how the drive can be controlled by external devices over
a communication network.
System overview
The drive can be connected to an external control system – usually a fieldbus
controller – via an adapter module. The drive can be set to receive all of its control
information through the external control interface, or the control can be distributed
between the external control interface and other available sources, for example,
digital and analogue inputs. The following diagram shows the control interfaces and
I/O connections of the drive.
