Message value: Component number: %1, component class target: %2, component class actual: %3, fault cause: %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. The component class, the component type or the number of connections differ. Alarm value (r2124, interpret hexadecimal): ddccbbaa hex: aa = component number of the component, bb = component class of the target tolopology, cc = component class of the actual topology, dd = fault cause dd = 01 hex = 1 dec: Different component class. dd = 02 hex = 2 dec: Different component type. dd = 03 hex = 3 dec: Different Order No. dd = 04 hex = 4 dec: Different number of connections. Note: Component class, component type and connec tion 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: Check the component soft-wired connections against t he hardware configuration of the drive unit in the commissioning software and correct differences. Note: Under "Topology --> Topology view" the commissi oning software offers improved diagnostics capability (e.g. setpoint/actual value comparison).
