Heidenhain Insufficient memory alarm: Insufficient memory

The TNC does not have enough memory to open, edit or load files/programs. It is an alarm from the Program area, and in the catalog it is listed as “Insufficient memory”. On the machine you notice it like this: Does not open program, Fails when loading a file, Control avisa de memoria.

On the shop floor it almost always comes from one of these causes: Demasiados programas, Archivo muy grande, Disco/control lleno, Archivos temporales. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reintentar tras liberar memoria. Resetting without fixing the cause first only hides the problem: Heidenhain Insufficient memory 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: Make a backup before deleting, Delete unused programs, Comprobar espacio de almacenamiento. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Heidenhain Insufficient memory 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 storage fails or does not free up space. 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 warning: the machine carries on, but it is flagging something that will get worse if you let it go. Deal with it between parts, not at the end of the shift. Guidance reference. Always confirm the full text in the exact machine/control manual.
