USS Setpoint Fault

Siemens · SINAMICS G120 Variable Speed Drive

What does F00072 mean?

The drive has failed to receive setpoint values via the USS (Universal Serial Interface) communication protocol within the configured telegram off time. This suggests a problem with the USS master device or the communication settings, causing the drive to lose its operational commands and halt controlled operation.

Complete Troubleshooting Guide

  1. 1

    Verify the USS master device for proper operation and configuration.

  2. 2

    Check and, if necessary, improve the monitoring time for USS telegrams in the STARTER software or relevant drive parameters.

  3. 3

    Inspect USS communication cabling for damage or loose connections.
