官方故障排除步驟

Message value: Component number: %1, Component class: %2, Component (target): %3, Connection number: %4 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The topology comparison has detected an EnDat enc oder in the actual topology that has been shifted with respect to the target topology. Alarm value (r2124, interpret hexadecimal): ddccbbaa hex: dd = connection number cc = component number bb = component class aa = component number of the component shifted in the target topology Note: The connection in the actual topology where the shifted component was detected is described in dd, cc and bb. Component class and connection number are described in F01375. The drive system is no longer booted. In this stat e, the drive control (closed-loop) cannot be enabled. Remedy: Adapting the topologies: - undo the change to the actual topology by changing over the DRIVE-CLiQ cables. - commissioning software: Go online, upload the dr ive unit, adapt the topology offline and download the modified project. - automatically remove the topology error (p9904). Note: Under "Topology --> Topology view" the commissi oning software offers improved diagnostics capability (e.g. setpoint/actual value comparison).
