What it means
F06504 reports that the island line supply synchronization at the infeed was unsuccessful: the synchronization process has remained in one of its states instead of completing. The drive does not shut down automatically when this fault is raised, and the fault value tells you the state in which the synchronization has remained.
Why it appears
- The island line supply synchronization did not succeed — the process has remained in one of its states rather than completing.
What to check
- Read the alarm value (r2124, interpret decimal) or r5482 to find out in which state the island line supply synchronization has remained.
- Check the conditions for the island line supply synchronization.
- Check the parameterization of the island line supply synchronization, in particular the island grid times in p5581.
Reading the message value
- The fault value is the alarm value that the drive also stores in r2124; interpret it as a decimal number.
- It contains the state in which the island line supply synchronization has remained — this corresponds to r5482 (Line synchronization status).
Parameters the manual names
- r2124 — alarm value of this fault; read it as a decimal number to see the state in which the island line supply synchronization has remained.
- r5482 — line synchronization status; the fault value of F06504 corresponds to it.
- p5581 — island grid times; check this parameterization when checking the island line supply synchronization.
Acknowledging and restarting
Acknowledge the fault immediately; a POWER ON is required before the drive can be restarted.
The same on every family
Every manual that describes F06504 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE (OFF1, OFF2) | IMMEDIATELY (POWER ON) | Network fault (2) | None | SINAMICS S120, S150 List Manual · p. 2769 |

Questions technicians ask
What does F06504 mean on a SINAMICS infeed?
The island line supply synchronization was unsuccessful: the synchronization process has remained in one of its states. The fault value (r2124, interpreted as a decimal number) shows which state — it corresponds to the line synchronization status in r5482.
How do I fix fault F06504?
Check the conditions for the island line supply synchronization and its parameterization, in particular the island grid times in p5581. The fault can then be acknowledged immediately, and a POWER ON is required before the drive can be restarted.
Where can I see the state the synchronization got stuck in?
In the fault value of F06504, which is the alarm value in r2124 read as a decimal number. The same state is shown by r5482, the line synchronization status.
