Siemens 61015 alarm: Cycle: contour not defined

The Siemens cycle cannot find the referenced contour to machine. It is an alarm from the Program area, and in the catalog it is listed as “Cycle: contour not defined”. On the machine you notice it like this: Fails when running the contour cycle, Cycle block message, Common after editing/renaming contours.

On the shop floor it almost always comes from one of these causes: Contour deleted or renamed, Etiquetas mal definidas, Post inconsistente. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after correcting contour definition. Resetting without fixing the cause first only hides the problem: Siemens 61015 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 the contour name/labels, Validate geometry in simulation, Revisar postprocesador. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Siemens 61015 active, avoid this: Do not delete blocks you do not understand, Do not run the cycle with a doubtful contour. Skipping any of these points is what turns a minor stop into an expensive breakdown.

Normally requires no maintenance. 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.
