Mazak 100/101/113 alarm: Soft limit or overtravel

Mazak detects software limit, soft limit or axis overtravel. It is an alarm from the Sobrecarrera area, and in the catalog it is listed as “Soft limit or overtravel”. On the machine you notice it like this: Axis locked by limit, It does not allow you to move in one direction, It may appear after offset or new program.

On the shop floor it almost always comes from one of these causes: Zero wrong piece, Tool length mal cargado, Program out of tour, Fixture mal posicionado. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after correcting origin and removing axis from the limit. Resetting without fixing the cause first only hides the problem: Mazak 100/101/113 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 offset and tool, Go out of the limit in a safe direction, Simular trayectoria. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Mazak 100/101/113 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 release or appeared after loss of reference/parameters. 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.
