Profibus Description

This chapter contains instructions for controlling the drive using a PLC over a Profibus™ network.
It addresses the following topics:
• Description of the interface
• User programming
• Parameter assignment and addressing
• Configuration and setup options
• Available functions
Description
The drive supports Profibus™ communication via an Anybus™ Profibus™ module. Profibus™
communication functions in the following way:
• Profibus™ is a token ring network.
Controller devices (or active stations) are those devices that initiate communication. When
a controller receives the "token" it may then perform controller-node communications with
its nodes (or passive stations).
• The drive acts as a node (passive station) on the Profibus™ network.
The drive auto detects the baud rate from the network.
• The Anybus™ module has a 9 pin DB-9F connector. Pin 3 is the positive data pin (RxD/TxD-P)
and pin 8 is the negative connection (RxD/TxD-N).
The modules support the following baud rates:
– 9.6 kbit/sec
– 19.2 kbit/sec
– 93.75 kbit/sec
– 187.5 kbit/sec
– 500 kbit/sec
– 1.5 Mbit/sec
– 3 Mbit/sec
– 6 Mbit/sec
– 12 Mbit/sec.
Profibus is a trademark of the Profibus Trade Organization.
To enable dual network functionality, this protocol requires an additional Anybus™ Profibus™
module.
