General Information About PROFIBUS for SINAMICS

General information
PROFIBUS is an open international field bus standard for a wide range of production and
process automation applications.
The following standards ensure open, multi-vendor systems:
● International standard EN 50170
● International standard IEC 61158
PROFIBUS is optimized for high-speed, time-critical data communication at field level.
Note
PROFIBUS for drive technology is standardized and described in the following document:
Reference: /P5/ PROFIdrive Profile Drive Technology
CAUTION
Before synchronizing to the isochronous PROFIBUS, all of the pulses of the drive objects
must be inhibited - also for those drives that are not controlled via PROFIBUS.
Technical data
To display information about the current operating state of the inverter and the
communication link, the PROFIBUS DP has three LEDs on the Standard Control Unit and
seven on the Control Unit with fail-safe functions.
Its voltage is supplied through the inverter system connector.
The PROFIBUS DP is connected to the PROFIBUS system using a 9-pin sub-D type socket
according to the PROFIBUS standard. All connections to this interface are short-circuit-proof
and isolated.
The PROFIBUS DP supports baud rates of 9.6 kbaud to 12 Mbaud.
