What it means
The manuals report A50006 as COMM BOARD: Alarm 6 for the G130, G150, S120 and S150. It is raised for the CBE20 SINAMICS Link communication board when the parameter assignment makes the sender and the receiver one and the same — a configuration the drive does not permit. In practice, a PZD receive address in p8872 has been given the same value as the node address in p8836, so the board would be exchanging data with itself. The same condition can also be raised as a fault; the drive then executes no automatic reaction, and that fault must be acknowledged immediately.
Why it appears
- On the CBE20 SINAMICS Link board, the parameter assignment indicates that the sender and the receiver are one and the same; this is not permitted.
- The affected PZD receive address in p8872 is set to the same value as the node address in p8836.
What to check
- Read the alarm value in r2124 and interpret it hexadecimal as yyyyxxxx hex: yyyy = info 1, xxxx = info 2.
- Info 1 (decimal) is the drive object number from p8872 and info 2 (decimal) is the index from p8872, so the alarm value identifies the p8872 index concerned.
- Compare the value stored in this p8872[index] with the node address in p8836.
- Correct the parameter assignment so that all p8872[index] are set to a value not equal to p8836.
Reading the message value
- The message value shows Info 1: %1, Info 2: %2 — the placeholders carry info 1 and info 2.
- Alarm value (r2124, interpret hexadecimal): yyyyxxxx hex: yyyy = info 1, xxxx = info 2.
- Info 1 (decimal) = drive object number from p8872.
- Info 2 (decimal) = index from p8872.
Parameters the manual names
- r2124 — alarm value; read it hexadecimal as yyyyxxxx to obtain the info 1 and info 2 of this alarm.
- p8872 — SINAMICS Link PZD receive address; all its indices must be set to a value not equal to p8836, and the alarm value names the affected index.
- p8836 — SINAMICS link node address; the value that no p8872 index may match.
Acknowledging and restarting
Correcting the parameter assignment is the whole remedy: once every p8872[index] holds a value not equal to p8836, the condition no longer exists. As an alarm, A50006 does not require an acknowledgement; if the drive has raised the same condition as a fault instead, that fault must be acknowledged immediately.
The same on every family
Every manual that describes A50006 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS S120, S150 List Manual · p. 3300 |
| G130, G150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS G130, G150 List Manual · p. 1937 |

Questions technicians ask
What does A50006 mean on a SINAMICS drive?
It is COMM BOARD: Alarm 6: the CBE20 SINAMICS Link parameter assignment makes the sender and the receiver one and the same, which is not permitted. In practice, a PZD receive address in p8872 equals the node address in p8836.
How do I fix alarm A50006?
Correct the parameter assignment so that all p8872[index] are set to a value not equal to p8836. The alarm value in r2124, read as yyyyxxxx hex, shows which p8872 index is affected.
Where can I see which p8872 index triggered A50006?
Read r2124 and interpret it hexadecimal: yyyy = info 1 (decimal: drive object number from p8872), xxxx = info 2 (decimal: index from p8872).
Does A50006 have to be acknowledged?
As an alarm it does not require an acknowledgement. If the drive raises the same condition as a fault, it executes no automatic reaction, but that fault must be acknowledged immediately.
