What it means
A07483 is an EPOS alarm. It is issued when a traversing block with travel to a fixed stop has reached that fixed stop, but the clamping torque or clamping force that was to be achieved there was not. The alarm comes without a message value, so it carries no additional coded information.
Why it appears
- The traversing block reached the fixed stop, but the clamping torque or clamping force had not been achieved at that point.
What to check
- Check the maximum torque-generating current, r1533.
- Check the torque limits, p1520 and p1521.
- Check the power limits, p1530 and p1531.
- Check the BICO interconnections of the torque limits, p1522, p1523, p1528 and p1529.
Parameters the manual names
- r1533 (Current limit torque-generating total / Iq_max total) — the maximum torque-generating current; this is the value the first check looks at.
- p1520 (CO: Force limit upper/motoring / F_max upper/mot) — the upper/motoring torque limit; check its setting.
- p1521 (CO: Force limit lower/regenerative / F_max lower/reg) — the lower/regenerative torque limit; check its setting.
- p1530 (Power limit motoring / P_max mot) — the motoring power limit; check its setting.
- p1531 (Power limit regenerative / P_max reg) — the regenerative power limit; check its setting.
- p1522 (CI: Force limit upper/motoring / F_max upper/mot) — BICO input for the upper/motoring torque limit; check the interconnection set here.
- p1523 (CI: Force limit lower/regenerative / F_max lower/reg) — BICO input for the lower/regenerative torque limit; check the interconnection set here.
- p1528 (CI: Force limit upper/motoring scaling / F_max up/mot scal) — BICO input for the scaling of the upper/motoring torque limit; check the interconnection set here.
- p1529 (CI: Force limit lower/regenerative scaling / F_max low/reg scal) — BICO input for the scaling of the lower/regenerative torque limit; check the interconnection set here.
Acknowledging and restarting
No acknowledgment is required — the drive specifies none for this alarm — and it triggers no automatic reaction. Nothing therefore has to be acknowledged or reset; the corrective work is the sequence of checks above.
The same on every family
Every manual that describes A07483 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2827 |
| G130, G150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1564 |

Questions technicians ask
What does alarm A07483 on a SINAMICS drive mean?
It is an EPOS alarm: the traversing block reached the fixed stop, but the clamping torque or clamping force that was to be achieved there was not reached.
How do I fix A07483, clamping torque not reached?
Check the maximum torque-generating current (r1533), the torque limits (p1520, p1521), the power limits (p1530, p1531) and the BICO interconnections of the torque limits (p1522, p1523, p1528, p1529).
Does A07483 have to be acknowledged?
No — the drive specifies no acknowledgment for this alarm and also takes no automatic reaction, so there is nothing to reset.
Is there a message value for A07483?
No. The alarm is raised without a message value, so no further information is coded into it.
