What it means
A08530 signals that the memory or the buffer status of the message channel of the PN/COMM board has an error — the message channel being the path over which the drive exchanges messages with the higher-level control system. Depending on the drive's configuration, the same condition can also be output as a fault; the behavior then is described under reset below.
Why it appears
- The buffer status of the message channel has an error (alarm value 0).
- The memory of the message channel has an error (alarm value 1).
What to check
- Read the alarm value in r2124 as a decimal number to determine whether the buffer status (0) or the memory (1) is affected.
- Check the communications link to the higher-level control system, as the remedy specifies.
Reading the message value
- The drive stores the alarm value in r2124; interpret it as a decimal number.
- 0: Error in the buffer status.
- 1: Error in the memory.
Parameters the manual names
- r2124 — alarm value: read it here (decimal) to see whether the message-channel error concerns the buffer status (0) or the memory (1).
Acknowledging and restarting
As an alarm, A08530 does not have to be acknowledged. If the drive is configured to output the same condition as a fault instead, no automatic shutdown is predefined for it; OFF1 and OFF2, and depending on the drive object also OFF3, can be set as the fault reaction, and the fault is acknowledged IMMEDIATELY.
The same on every family
Every manual that describes A08530 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. 2921 |
| G130, G150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS G130, G150 List Manual · p. 1636 |

Questions technicians ask
What does A08530 PN/COMM BOARD: Message channel error mean?
The drive has detected an error in the memory or the buffer status of the message channel used for communication with the higher-level control system. The alarm value in r2124 tells which part is affected: 0 for the buffer status, 1 for the memory.
How do I fix A08530?
The remedy is to check the communications link. Read r2124 first to see whether the buffer status or the memory of the message channel is affected.
Does A08530 have to be acknowledged?
No — as an alarm it requires no acknowledgment. If your drive outputs the condition as a fault, the fault is acknowledged IMMEDIATELY, and by default the drive does not shut down automatically.
What does alarm value 1 mean for A08530?
An alarm value of 1, read in r2124 as a decimal number, means an error in the memory of the message channel; a value of 0 means an error in the buffer status.
