Communication via PROFIBUS DP

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.

PROFIBUS for drive technology is standardized and described in the following document:

Reference: /P5/ PROFIdrive Profile Drive Technology

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.

The cyclic PZD channel is deactivated when the CBE20 is plugged in!

No CAN cables must be connected to interface X126. If CAN cables are connected, the

CU320 and other CAN bus nodes may be destroyed.
