What it means
The EPOS function raises this message when a traversing block whose block change enable is set to CONTINUE_EXTERNAL_ALARM is processed although the external block change was not requested. The alarm value in r2124 identifies the affected traversing block. Depending on how the drive is configured, the same condition can also be issued as a fault.
Why it appears
- A traversing block with the block change enable CONTINUE_EXTERNAL_ALARM was processed, and for this traversing block the external block change was not requested.
What to check
- Read the alarm value in r2124 and interpret it as a decimal number to identify the number of the traversing block concerned.
- Resolve the reason why the edge is missing at the binector input (BI: p2632) at which the external block change is requested.
Reading the message value
- The message value is the alarm value stored in r2124; interpret it as a decimal number.
- The value is the number of the traversing block in which the external block change was not requested.
Parameters the manual names
- r2124 (alarm value) — read here and interpret as a decimal number to identify the traversing block concerned.
- p2632 (EPOS external block change evaluation / Ext blk chg eval) — the binector input (BI) whose edge must request the external block change; check here why the edge is missing.
Acknowledging and restarting
As an alarm, the message requires no acknowledgement. If the drive configuration issues the same condition as a fault instead, the drive executes OFF1 and the fault must be acknowledged IMMEDIATELY before the drive can run again.
The same on every family
Every manual that describes A07463 gives it the same reaction, acknowledgement and message class.

| G130, G150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1559 |

Questions technicians ask
What does the SINAMICS alarm A07463 mean?
It reports that a traversing block with the block change enable CONTINUE_EXTERNAL_ALARM was processed although the external block change was not requested — the edge at the binector input (BI: p2632) is missing.
How do I find the traversing block behind A07463?
The alarm value in r2124 contains the number of the affected traversing block. Interpret the value as a decimal number.
How do I fix alarm A07463?
Resolve the reason why the edge is missing at the binector input (BI: p2632). As an alarm the message needs no acknowledgement; only the fault variant must be acknowledged IMMEDIATELY.
What happens when A07463 occurs as a fault?
The drive then executes OFF1, and the fault must be acknowledged IMMEDIATELY before the drive can run again.
