What it means
This fault is raised during the EPOS search for reference: when the axis reached the zero mark it also reached the end of the traversing range without detecting an edge at the binector input "reference cam" (BI: p2612)
. The manuals print no message value for this fault, so there is no value decoding to read out.
Why it appears
- During the search for reference, the drive sees no edge at the binector input "reference cam" that is interconnected at BI: p2612 while the axis, on arriving at the zero mark, reaches the end of its traversing range. The manual states the maximum traversing range as -2147483648 [LU] ... -2147483647 [LU].
What to check
- Check the binector input "reference cam" — the signal the search for reference evaluates is interconnected at BI: p2612.
- Repeat the search for reference.
Parameters the manual names
- p2612 — BI: EPOS search for reference reference cam. The reference cam signal for the search for reference is interconnected at this input; check and correct the interconnection here before repeating the search.
Acknowledging and restarting
Clear the cause first: check and correct the signal at the binector input "reference cam" (BI: p2612). Then acknowledge the fault and repeat the search for reference, in that order.
What differs between the drive families
Straight from the manuals' own fields — F07460 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (OFF2, OFF3) | — | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2821 |
| G130, G150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1558 |

Questions technicians ask
What does fault F07460 mean on a SINAMICS drive?
It is an EPOS fault: during the search for reference the axis reached the end of its traversing range when it arrived at the zero mark, and no edge was detected at the binector input "reference cam" (BI: p2612). The maximum traversing range is -2147483648 [LU] ... -2147483647 [LU].
How do I clear fault F07460?
Check the "reference cam" binector input interconnected at BI: p2612, then repeat the search for reference. These are the two steps the remedy names for this fault.
Which parameter belongs to F07460?
p2612, the binector input for the EPOS search-for-reference reference cam. Check what is interconnected there when the fault appears.
Why does the search for reference abort with F07460?
Because the drive detects no edge at the reference cam input while the search runs: the axis reaches the end of the traversing range at the zero mark without the drive having seen an edge at BI: p2612.
