Powering up stopped due to "STO via Power Module terminals"
Siemens · SINAMICS G120 Safety Functions
What does A01790 mean?
The inverter's automatic self-test during power-up was interrupted because the 'STO via Power Module terminals' function is active. This prevents the drive from completing its initialization and starting normally, indicating an unintended or misconfigured safety state at startup.
