A01482 — Topology: Sensor Module not connected

A01482 is raised by the drive's topology comparison: a Sensor Module that exists in the target topology — the project in the commissioning software — is not present at the expected connection in the actual topology. The alarm text names the missing component and the connection it belongs to. The drive itself takes no automatic action; correcting either the hardware or the project is up to you. The same topology comparison covers other component classes as well (power unit, Terminal Module, DRIVE-CLiQ Hub Module, Controller Extension, DRIVE-CLiQ component, option slot component, motor with DRIVE-CLiQ), each with its own alarm number.

• The topology comparison has detected a Sensor Module that is missing in the actual topology with respect to the target topology — a component configured in the project has not been inserted at the connection where it is expected.

1. Correct the actual topology: insert the components involved at the right connection.
2. Alternatively, 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.
6. For improved diagnostics, open Topology --> Topology view in the commissioning software; where relevant it offers, for example, a setpoint/actual value comparison.

The drive stores the alarm value of this message in r2124 and interprets it hexadecimal as ddccbbaa. The alarm text reads Component: %1, to %2, %3, connection: %4; the bytes of the alarm value correspond to these placeholders:

• aa — component number of the component that has not been inserted (%1)
• bb — component class (%2)
• cc — component number (%3)
• dd — connection number (%4)

The component that has not been inserted is described by the combination of dd, cc and bb. The component classes and connection numbers are described in the manual under F01375.

• r2124 (alarm value) — read the hexadecimal ddccbbaa pattern here to identify the connection number, component class and component number belonging to the missing Sensor Module.

This alarm does not have to be acknowledged. It is withdrawn automatically once the discrepancy between the actual and the target topology has been removed — either by inserting the Sensor Module again at the correct connection or by adapting the project/parameterization in the commissioning software to the hardware actually connected.
