A0922 alarm in siemens micromaster 420 or MM420 drive -  comes when no load is connected to the inverter, therefore several functions can run differently than under normal load condition.

Cause : Comes when no load is connected to the inverter, therefore several functions can run differently than under normal load condition.

1. Check that load is applied to the inverter.

2. Check motor parameters correspond to motor attached.

3. As a result, some functions may not work correctly, because there is no normal load condition.
