What it means
A07466 is an EPOS alarm that signals a parameterization error in the traversing blocks: the same traversing block number was assigned a multiple number of times. The drive detects this duplicate numbering in the traversing block configuration and reports it as an error in the parameterization/commissioning procedure, not as a hardware fault.
Why it appears
- The same traversing block number was assigned a multiple number of times.
What to check
- Read the alarm value in r2124; interpreted as a decimal number, it is the number of the traversing block that was assigned a multiple number of times.
- Search the traversing blocks for the blocks that carry this number.
- Correct the traversing blocks so that no traversing block number is assigned more than once.
Reading the message value
- Alarm value (r2124, interpret decimal):
Number of the traversing block that was assigned a multiple number of times.
Parameters the manual names
- r2124 — alarm value: read it as a decimal number to obtain the number of the traversing block that was assigned a multiple number of times.
Acknowledging and restarting
No acknowledgement is required for this alarm, and the drive executes no automatic reaction. The reset consists of correcting the traversing block numbering; once no traversing block number is assigned a multiple number of times, the alarm condition no longer exists.
The same on every family
Every manual that describes A07466 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2823 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1560 |

Questions technicians ask
What does alarm A07466 mean on a SINAMICS drive?
It is an EPOS alarm telling you that the same traversing block number was assigned a multiple number of times — a parameterization error in the traversing blocks, not a hardware fault.
How do I find the duplicated traversing block?
Read the alarm value in r2124; interpreted as a decimal number it contains the number of the traversing block that was assigned a multiple number of times. Then correct the traversing blocks.
Does A07466 have to be acknowledged?
No. The alarm requires no acknowledgement and the drive executes no automatic reaction; correcting the traversing block numbering is the whole remedy.
Why is my drive showing A07466?
Because the same traversing block number exists more than once in the traversing block configuration. Give every traversing block its own number so the duplicate is removed.
