Siemens · SINAMICS G120C Variable Speed Drive

What does A30034 mean?

The alarm threshold for the power unit's internal temperature has been reached. This indicates that the internal components are operating at elevated temperatures, potentially due to high ambient temperature, insufficient cooling, or a fan failure. If the temperature continues to rise, it may trigger fault F30036, leading to a drive trip and potential hardware damage.

Complete Troubleshooting Guide
