What it means
Alarm A07480 reports that the axis is at the position of the software limit switch plus in EPOS. Because the axis stands at this limit, the traversing block that was active was interrupted. The G130/G150 and S120/S150 list manuals describe this alarm identically, so the notes below apply to both. No message value is supplied with this alarm.
Why it appears
- The axis is at the position of the software limit switch plus.
- The traversing block that was active was interrupted.
What to check
- Correct the target position of the interrupted traversing block.
- If the plus limit itself should lie elsewhere, change the software limit switch plus — the remedy names the signal source interconnection (CI: p2579) and p2581 for this.
Parameters the manual names
- p2579 (CI, “SW lim sw plus s_s”): signal source of the EPOS software limit switch plus — interconnect here the source the plus limit position is taken from when you change the limit.
- p2581 (CO, “SW lim sw plus”): the EPOS software limit switch plus — the plus limit position; one of the two places the remedy names for changing the limit.
- p2582 (BI, “SW lim sw act”): EPOS software limit switch activation — switches the software limit switch on and off; the manual lists it as a related parameter for this alarm.
Acknowledging and restarting
This alarm requires no acknowledgement. It reports a positional condition — the axis stands at the software limit switch plus and the active traversing block was interrupted — so deal with the cause as described above: correct the target position, or change the software limit switch plus via p2579 and p2581.
The same on every family

Questions technicians ask
What does SINAMICS alarm A07480 mean?
It reports that the axis is standing at the position of the EPOS software limit switch plus, and that the traversing block which was active was interrupted.
How do I acknowledge or clear A07480?
No acknowledgement is required. Deal with the cause instead: correct the target position, or change the software limit switch plus via p2579 and p2581.
Which parameters set the software limit switch plus behind A07480?
p2579 interconnects the signal source (CI) of the plus limit and p2581 is the limit position itself (CO); p2582 (BI) is the activation of the software limit switch and is listed as related.
Why was my EPOS traversing block interrupted with A07480?
Because the axis reached the position of the software limit switch plus — interrupting the active traversing block is part of this alarm condition.
