What it means
F07492 EPOS: STOP cam plus reached tells the technician that the drive has detected a 0 signal at binector input p2570, the input assigned to the EPOS STOP cam plus — in other words, the STOP cam plus was reached. Depending on how the drive is configured, the same condition can also be output as an alarm (A) instead of a fault.
Why it appears
- The binector input p2570 carries a 0 signal; for the drive this means the STOP cam plus has been reached.
- The STOP cam plus was reached while the axis was traversing in the negative direction; the drive takes this as an indication that the wiring of the STOP cam is incorrect.
What to check
- Leave the STOP cam plus by traversing in the negative direction and return the axis to the valid traversing range.
- Check the wiring of the STOP cam.
Parameters the manual names
- p2570 (BI: EPOS STOP cam plus / STOP cam plus) — the binector input at which the drive evaluates the plus STOP cam; the 0 signal on this input is what raises F07492.
Acknowledging and restarting
As a fault, the message stops the drive with OFF3 and must be acknowledged immediately; traversing can only resume once the axis has left the STOP cam plus and is back inside the valid traversing range. When the same condition is issued as an alarm, it triggers no reaction and does not need to be acknowledged.
The same on every family
Every manual that describes F07492 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF3 | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2829 |
| G130, G150 | OFF3 | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1566 |

Questions technicians ask
What does SINAMICS fault F07492 mean?
The EPOS function reports that the STOP cam plus was reached: the drive sees a 0 signal at binector input p2570.
Why does F07492 come up while the axis traverses in the negative direction?
Reaching the plus cam on a negative traversing move is not expected, so the drive takes it as a sign that the wiring of the STOP cam is incorrect.
How do I clear F07492?
Traverse in the negative direction to leave the STOP cam plus and bring the axis back into the valid traversing range, check the STOP cam wiring, then acknowledge the fault immediately.
Can F07492 also appear as an alarm?
Yes, depending on the drive configuration the same condition can be output as an alarm; as an alarm it triggers no reaction and requires no acknowledgement.
