A01389 — Topology: Motor with DRIVE-CLiQ incorrectly inserted

A01389 is raised by the drive's topology comparison: it has found a motor with DRIVE-CLiQ in the actual topology that is incorrectly inserted with respect to the target topology — the motor sits at a DRIVE-CLiQ connection other than the one the project expects. While this topology error is present, the drive system is no longer booted, and in this state the drive control (closed-loop) cannot be enabled. The alarm itself triggers no further automatic response from the drive; the effective consequence is the blocked boot and the disabled closed-loop control.

• A motor with DRIVE-CLiQ is inserted at a connection that does not match the target topology, and the topology comparison detects this difference between the actual and the target topology.

1. Identify the components involved from the alarm value in r2124 (see below).
2. Under Topology --> Topology view the commissioning software or commissioning tool offers improved diagnostics capability where relevant, for example a setpoint/actual value comparison, showing where the actual and the target topology differ.
3. Either insert the components involved at the right connection, correcting the actual topology, or adapt the project/parameterization in the commissioning software, correcting the target topology.
4. Alternatively, remove the topology error automatically with p9904.

The alarm text names the affected component and the connection: Component: %1, to %2, %3, connection: %4. The alarm value for this alarm is stored in r2124 and must be interpreted hexadecimal; it is structured as ddccbbaa:

• dd = connection number (%4)
• cc = component number (%3)
• bb = component class (%2)
• aa = component number of the incorrectly inserted component (%1)

The component is described in dd, cc and bb, where the component involved is incorrectly inserted. What the component class and the connection number mean is described in F01375.

• r2124 (alarm value): holds the alarm value for A01389; read it hexadecimal as ddccbbaa to identify the connection, the component number, the component class and the incorrectly inserted component.
• p9904 (Topology comparison acknowledge differences): use it to have the topology error removed automatically instead of re-plugging the hardware or re-projecting.

This alarm requires no acknowledgement. It ends when the topology error is gone: after the motor has been inserted at the right connection, after the project (target topology) has been adapted to the hardware actually connected, or after the topology error has been removed automatically with p9904. As long as the error is present, the drive system is not booted and the closed-loop drive control cannot be enabled, so the drive becomes ready for operation only once the actual and the target topology match.
