官方故障排除步驟

Message value: Component number: %1, Component class: %2, Connection number1: %3, Connection number2: %4 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The topology comparison has detected differences in the actual and target topologies in relation to one component. A component was connected to another connection. The different connections of a component are described in the alarm value: Alarm value (r2124, interpret hexadecimal): ddccbbaa hex: dd = connection number of the target topology cc = connection number of the actual topology bb = component class aa = component number Note: 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: - change over the actual topology to match the target topology. - download the target topology that matches the actual topology (commissioning software). - 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). See also: p9904 (Topology comparis on, acknowledge differences)
