What it means
F08500 is reported when the monitoring time that the drive grants for the configuration has expired: the transfer of the configuration data between the drive and the higher-level control system did not complete within the allowed time. The drive stores the exact reason as a fault value in r0949 and outputs it as the message value. The same condition can also be signalled as an alarm (A); in that form it triggers no reaction and requires no acknowledgement. Closely related communication-board messages such as F08501, F08502 and F08510 describe other monitoring functions and are covered on their own pages.
Why it appears
- The monitoring time for the configuration has expired — the transfer of the configuration data took longer than the drive allows for it.
What to check
- Check the communications link between the drive and the higher-level control system.
Reading the message value
- The drive stores the fault value in r0949; interpret it as a decimal number.
- 0 — the transfer time of the send configuration data has been exceeded.
- 1 — the transfer time of the receive configuration data has been exceeded.
Parameters the manual names
- r0949 — displays the fault value for this message; read it as a decimal number to see whether the send configuration data (0) or the receive configuration data (1) exceeded its transfer time.
Acknowledging and restarting
Check the communications link first; the fault can only be cleared once its cause is gone. The message must then be acknowledged immediately, after which the drive can be restarted. If the drive is configured to output the condition as an alarm instead of a fault, no acknowledgement is required.
What differs between the drive families
Straight from the manuals' own fields — F08500 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: OFF1 (OFF2) Servo: OFF1 (OFF2, OFF3) Vector: OFF1 (OFF2, OFF3) Hla: OFF1 (OFF2, OFF3) | IMMEDIATELY | Communication error to the higher-level control system (9) | None | SINAMICS S120, S150 List Manual · p. 2917 |
| G130, G150 | Vector: OFF1 (OFF2, OFF3) Infeed: OFF1 (OFF2) | IMMEDIATELY | Communication error to the higher-level control system (9) | None | SINAMICS G130, G150 List Manual · p. 1633 |

Questions technicians ask
What does fault F08500 mean on a SINAMICS drive?
The monitoring time for the configuration has expired: the transfer of the configuration data on the communication board took longer than permitted. The fault value in r0949 shows whether the send (0) or the receive (1) direction was too slow.
How do I clear F08500?
The manuals give one remedy: check the communications link. Once the link is okay again, acknowledge the fault immediately and restart the drive.
What is the fault value of F08500?
It is stored in r0949 and is read as a decimal number: 0 means the transfer time of the send configuration data was exceeded, 1 means the transfer time of the receive configuration data was exceeded.
Can F08500 also appear as an alarm?
Yes, the manuals list the condition as available as an alarm (A) as well. In that form it triggers no reaction and needs no acknowledgement.
