Heidenhain 60 alarm: TOOL DEF duplicated with PGM CALL

The TNC detects the same tool defined more than once in nested programs. It is an alarm from the Program area, and in the catalog it is listed as “TOOL DEF duplicated with PGM CALL”. On the machine you notice it like this: Fails when calling the subprogram, Error related to TOOL DEF/PGM CALL.

On the shop floor it almost always comes from one of these causes: Same TOOL DEF number in main and subprogram, Post duplicando definiciones, Plantilla CAM mal configurada. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after correcting the program and verifying simulation. Resetting without fixing the cause first only hides the problem: Heidenhain 60 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: Find duplicate TOOL DEF, Revisar subprogramas llamados, Corregir post/plantilla. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Heidenhain 60 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.

Normally it does not require maintenance except file corruption. 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.
