Fieldbus Timeout

SEW Eurodrive · MOVIDRIVE compact System

What does 28 mean?

Communication between the fieldbus master and the MOVIDRIVE® slave has been interrupted or failed to occur within the projected response monitoring time. This fault leads to a rapid stop, indicating a loss of control from the fieldbus system.

Complete Troubleshooting Guide

  1. 1

    Check the communication routine and configuration settings of the fieldbus master for correct operation.

  2. 2

    Extend the fieldbus timeout time (P819) if communication is intentionally slower, or deactivate monitoring if not critical for the application.
