Power unit: Air intake overtemperature
Siemens · SINAMICS G120C Variable Speed Drive
What does F30035 mean?
The air intake temperature in the power unit has exceeded the permissible limit, typically 55 °C. This condition signifies critical overheating of the incoming air, often caused by high ambient temperatures, insufficient airflow, or a fan failure. This fault forces an OFF1 or OFF2 reaction, stopping the drive, and cannot be acknowledged until the temperature falls below the alarm threshold of A05002.
