Heidenhain 58 alarm: Stroke limit/path out of range

The TNC calculates a path that exceeds machine limits or permitted range. It is an alarm from the Sobrecarrera area, and in the catalog it is listed as “Stroke limit/path out of range”. On the machine you notice it like this: Error in test run or execution, The toolpath does not fit within the travel, May be linked to the datum/origin.

On the shop floor it almost always comes from one of these causes: Datum incorrecto, Coordenadas fuera de rango, Incorrect transformation or active plane, Wrong tool/corrector. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Correct program/origin and reset. Resetting without fixing the cause first only hides the problem: Heidenhain 58 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 datum and BLK FORM, Simular trayectoria, Comprobar transformaciones PLANE/CYCL activas. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Heidenhain 58 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 the axis physically reaches the limit or there is a reference error. 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.
