官方故障排除步骤
Message value: Component number: %1 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The topology comparison has detected a controller extension 32 (CX32) in the target topology that is not available in the actual topology. Alarm value (r2124, interpret decimal): Component number of the additional target components. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Remedy: - delete the CX32 / NX in the commissioning softwar e project and download the new configuration to the drive unit. - check that the actual topology matches the target topology and if required, change over. - check DRIVE-CLiQ cables for interruption and contact problems. - check the 24 V supply voltage. - check that CX32/NX functions correctly. Note: Under "Topology --> Topology view" the commissi oning software offers improved diagnostics capability (e.g. setpoint/actual value comparison).
