F00015

Motor temperature signal lost

Siemens · SINAMICS G120 Variable Speed Drive

What does F00015 mean?

The motor temperature sensor has an open or short circuit, causing a loss of its signal. This results in the drive's temperature monitoring switching to a thermal model instead of direct sensor input, which can lead to inaccurate temperature protection if the underlying issue is not resolved. Continuous operation with a faulty sensor could lead to motor overheating and damage.
