Profibus Communication

6.1 Description

6.1 Description
The drive supports Profibus™ communication via an Anybus™ Profibus™ module.
Profibus™ communication functions in the following way:
● Profibus™ is a token ring network. Master devices (or active stations) are those devices
that initiate communication. When a master receives the "token" it may then perform master-
slave communications with its slaves (or passive stations).
● The drive acts as a slave (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.
