A01486 alarm in siemens 6RA80 DC Drive indicate that the DRIVE-CLiQ component not inserted. This means the topology comparison has detected a DRIVE-CLiQ component missing in the actual topology with respect to the target topology.

1. Insert the components involved at the right connection (correct the actual topology).
2. Adapt the project/parameterization in the commissioning software (correct the target topology).
3. Check the 24 V supply voltage.
4. Check DRIVE-CLiQ cables for interruption and contact problems.
5. Check that the component is working properly.
