What it means
A01383 is signalled when the drive's topology comparison detects a Terminal Module in the actual topology — what is physically plugged together — that has been incorrectly inserted with respect to the target technology, i.e. the configuration held in the project. The message appears as an alarm. While it is present, the drive system is no longer booted and the drive control (closed-loop) cannot be enabled. The message value names the component and the connection involved, and the alarm value in r2124 carries the same information in coded form. For closer diagnosis, Topology --> Topology view
in the commissioning software (commissioning tool) where relevant offers improved diagnostics capability, for example a setpoint/actual value comparison.
Why it appears
- The topology comparison has detected a Terminal Module in the actual topology that has been incorrectly inserted with respect to the target technology — the module is plugged into a connection other than the one the project expects.
What to check
- Read the message value and the alarm value in r2124 (interpreted hexadecimal) to identify the connection and the component involved; component class and connection number are described under F01375.
- Insert the components involved at the right connection — this corrects the actual topology.
- Alternatively, adapt the project/parameterization in the commissioning software so the target topology matches what is actually plugged in.
- Alternatively, automatically remove the topology error with p9904.
- If needed, use
Topology --> Topology view
in the commissioning software for the improved diagnostics capability, e.g. to compare setpoint and actual value.
Reading the message value
- The message value reads: Component: %1, to %2, %3, connection: %4 — the drive fills the four placeholders with the numbers coded in the alarm value.
- The alarm value is stored in r2124 and is interpreted hexadecimal as ddccbbaa.
- aa = component number of the incorrectly inserted component (%1)
- bb = component class (%2)
- cc = component number (%3)
- dd = connection number (%4)
- The component involved is described in dd, cc and bb; the manual decodes component class and connection number under F01375.
Parameters the manual names
- r2124 (Alarm value): read the coded alarm value here — it holds the connection number, the component number, the component class and the component number of the incorrectly inserted Terminal Module.
- p9904 (Topology comparison acknowledge differences / Topo_compare ackn): use this parameter to automatically remove the topology error instead of re-inserting the module or changing the project.
Acknowledging and restarting
No acknowledgement is required for this alarm. It is remedied on the topology itself: insert the Terminal Module at the right connection, adapt the project/target topology in the commissioning software, or remove the topology error automatically with p9904. As long as the discrepancy exists, the drive system is not booted and closed-loop control cannot be enabled.
The same on every family
Every manual that describes A01383 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1413 |
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2603 |

Questions technicians ask
What does alarm A01383 mean on a SINAMICS drive?
The topology comparison has detected a Terminal Module in the actual topology that is incorrectly inserted with respect to the target technology. In this state the drive system is no longer booted and closed-loop control cannot be enabled.
How do I fix alarm A01383?
Insert the Terminal Module at the right connection to correct the actual topology, or adapt the project/parameterization in the commissioning software to correct the target topology. Alternatively, remove the topology error automatically with p9904.
How is the A01383 alarm value in r2124 decoded?
Interpret r2124 hexadecimal as ddccbbaa: dd is the connection number (%4), cc the component number (%3), bb the component class (%2) and aa the component number of the incorrectly inserted component (%1). Component class and connection number are described under F01375.
Can the drive still be operated with A01383 active?
No. The drive system is no longer booted in this state, and the drive control (closed-loop) cannot be enabled until the topology discrepancy is removed.
