What it means
A01099 is raised when the tolerance (p3109) set for UTC synchronization is violated — the deviation between the time of day master and the drive system lies outside this tolerance. UTC: Universal Time Coordinates. Depending on the drive's configuration, the same condition can also be output with no reaction (N).
Why it appears
- The tolerance (p3109) set for UTC synchronization was violated, so the deviation between the time of day master and the drive system lies outside this tolerance.
What to check
- Read the deviation that occurred when synchronizing in r3107.
- Shorten the synchronization intervals so that the deviation between the time of day master and the drive system lies within the tolerance set in p3109.
Parameters the manual names
- p3109 (UTC synchronization tolerance) — the tolerance that the deviation between the time of day master and the drive system must stay within; A01099 is raised when it is violated.
- r3107 (UTC synchronization time out of tolerance) — shows the deviation present when synchronizing; use it to check the actual time deviation.
Acknowledging and restarting
No acknowledgement is required. The remedy is to shorten the synchronization intervals until the deviation shown in r3107 lies within the tolerance set in p3109.
The same on every family
Every manual that describes A01099 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. 2577 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1389 |

Questions technicians ask
What does alarm A01099 mean in SINAMICS?
The tolerance (p3109) set for UTC synchronization was violated: the deviation between the time of day master and the drive system lies outside the tolerance. UTC stands for Universal Time Coordinates.
How do I fix alarm A01099?
Shorten the synchronization intervals so that the deviation between the time of day master and the drive system lies within the p3109 tolerance. The deviation when synchronizing is shown in r3107.
Does A01099 have to be acknowledged?
No, no acknowledgement is required. Depending on the drive's configuration, the condition can also be output with no reaction (N).
Where can I see the time deviation that triggers A01099?
In r3107 (UTC synchronization time out of tolerance), which shows the deviation present when synchronizing.
