What it means
F07482 is raised by the EPOS function when the actual position of the axis is greater than the position of the software limit switch plus — in other words, the axis stands beyond its plus software limit. The G130/G150 and S120/S150 manuals describe the message identically. As a fault the drive responds with OFF1, with OFF2 or OFF3 as possible alternatives; depending on the drive configuration, the same condition can also be issued as an alarm, which then causes no automatic reaction.
Why it appears
- The actual position of the axis lies above the position of the software limit switch plus — the axis has passed the plus software limit that EPOS monitors. This is the only cause the manuals give.
What to check
- Correct the target position if it lies beyond the software limit switch plus.
- If the limit itself is wrong for the application, change the software limit switch plus: p2579 selects the signal source from which the drive takes the plus limit, and p2581 holds the limit value.
Parameters the manual names
- p2579 (CI: EPOS software limit switch plus signal source) — selects where the drive takes the value of the software limit switch plus from; use it when rerouting the plus limit.
- p2581 (CO: EPOS software limit switch plus) — holds the value of the software limit switch plus that the actual position is compared against; change it here to move the plus limit.
- p2582 (BI: EPOS software limit switch activation) — the signal that activates the software limit switch monitoring; the S120/S150 entry lists it under the cross-references for this fault.
Acknowledging and restarting
Acknowledge the fault immediately once the target position or the limit has been corrected, then restart the drive. No acknowledgement is required when the condition is only present as an alarm.
The same on every family
Every manual that describes F07482 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2827 |
| G130, G150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1564 |

Questions technicians ask
What does SINAMICS fault F07482 mean?
The EPOS function has detected that the actual position of the axis is greater than the position of the software limit switch plus, so the axis is beyond its plus software limit.
How do I clear fault F07482?
Correct the target position, or change the software limit switch plus via p2581 (limit value) and p2579 (signal source); acknowledge the fault immediately afterwards and restart.
Which parameters belong to F07482?
p2579 selects the signal source of the software limit switch plus, p2581 is the plus limit value itself, and p2582 is the signal that activates the software limit switch monitoring.
Can F07482 also appear as an alarm?
Yes. Depending on the drive configuration the same condition can also be issued as an alarm, which then causes no automatic reaction and requires no acknowledgement.
