A01489 — Topology: motor with DRIVE-CLiQ not connected

A01489 is raised by the drive's topology comparison: a motor with DRIVE-CLiQ that belongs to the target topology is missing in the actual topology — the component is not inserted at the connection where the project expects it. The discrepancy can lie on the hardware side or on the project side. Where relevant, the commissioning software offers improved diagnostics under 'Topology --> Topology view', for example a setpoint/actual value comparison.

• A motor with DRIVE-CLiQ that the target topology expects is not present in the actual topology the drive sees — the component has not been inserted where the project expects it.
• The mismatch can lie on either side: the hardware does not correspond to the project, or the project/parameterization in the commissioning software does not describe the hardware as actually connected.

1. Correct the actual topology: insert the components involved at the right connection.
2. Or correct the target topology: adapt the project/parameterization in the commissioning software so that it matches the hardware actually connected.
3. Check the 24 V supply voltage.
4. Check the DRIVE-CLiQ cables for interruption and contact problems.
5. Check that the component is working properly.

• The message value names the component and its connection: 'Component: %1, to %2, %3, connection: %4'.
• The drive stores the alarm value in r2124, to be interpreted hexadecimal as ddccbbaa.
• dd = connection number (%4).
• cc = component number (%3).
• bb = component class (%2).
• aa = component number of the component that has not been inserted (%1).
• The component that has not been inserted is described by dd, cc and bb; component class and connection number are described in F01375.

• r2124 (alarm value) — read it hexadecimal as ddccbbaa to identify the connection number, the component number, the component class and the component that has not been inserted.

A01489 requires no acknowledgment. The alarm only reports the mismatch between actual and target topology; once the motor with DRIVE-CLiQ has been inserted at the correct connection, or the target topology has been adapted to the existing hardware, the condition the topology comparison detects is resolved.
