A01385 — Topology: Controller Extension incorrectly inserted

A01385 is an alarm from the drive's topology comparison: a controller extension 32 (CX32) has been found in the actual topology that is inserted incorrectly with respect to the target topology. The manuals title it Topology: Controller Extension incorrectly inserted. While the error is present, the drive system is no longer booted and the drive control (closed-loop) cannot be enabled. The message value names the affected component (Component: %1, to %2, %3, connection: %4), and the alarm value in r2124 identifies the connection and the component that is incorrectly inserted.

• The topology comparison has found a controller extension 32 (CX32) in the actual topology that is not inserted where the target topology expects it.

1. Open Topology → Topology view in the commissioning software, where relevant: it offers improved diagnostics capability, e.g. a setpoint/actual value comparison.
2. Insert the components involved at the right connection; this corrects the actual topology.
3. Alternatively, adapt the project/parameterization in the commissioning software; this corrects the target topology.
4. Alternatively, remove the topology error automatically with p9904.

• The alarm value is stored in r2124 and is to be interpreted hexadecimal: ddccbbaa hex.
• dd = connection number (%4)
• cc = component number (%3)
• bb = component class (%2)
• aa = component number of the incorrectly inserted component (%1)
• The component involved is described by dd, cc and bb; the component class and the connection number are described under F01375.

• r2124 (Alarm value): read the alarm value here and interpret it hexadecimal to identify the connection, the component class and the component numbers of the incorrectly inserted CX32.
• p9904 (Topology comparison acknowledge differences / Topo_compare ackn): the remedy offers this parameter for removing the topology error automatically.

No acknowledgment is required for this alarm. Once the discrepancy between the actual and the target topology has been eliminated — the CX32 inserted at the correct connection, the project adapted in the commissioning software, or the topology error removed automatically with p9904 — the alarm is cleared.
