Siemens 10630/10631 alarm: Axis at work area limit

Sinumerik indicates that an axis reaches or remains at the limit of the work area. It is an alarm from the Sobrecarrera area, and in the catalog it is listed as “Axis at work area limit”. On the machine you notice it like this: The block does not continue, Axis near the software limit, It can happen in MDA/automatic.

On the shop floor it almost always comes from one of these causes: Offset incorrecto, Limited work area, Trayectoria fuera de rango, Active transformation. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after correcting position/program. Resetting without fixing the cause first only hides the problem: Siemens 10630/10631 trips again and, in the meantime, you keep working with the machine in bad shape.

With the machine stopped and in a safe state, start with these checks: Check zero piece and limits, Check the commanded coordinate, Remove shaft in safe direction. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Siemens 10630/10631 active, avoid this: Do not bypass safety devices, Do not manipulate energized electrical cabinet, Do not continue producing if the alarm reappears. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If it does not match the real position or appeared after machine data changes. If you are not sure how far it goes, stop the machine and report it: a repeat alarm always works out cheaper than a crash.

It is a stop alarm: the cycle will not continue until you fix the cause. It does not always mean serious damage, but it leaves the machine where it is and you have to check it before running again. Guidance reference. Always confirm the full text in the exact machine/control manual.
