Siemens 50010 alarm: Tool data error

The control does not accept or find necessary tool/offset data. It is an alarm from the Program area, and in the catalog it is listed as “Tool data error”. On the machine you notice it like this: Failure in TOOL CALL or tool change, It cannot find the length/radius/offset.

On the shop floor it almost always comes from one of these causes: Tool not created, Offset incompleto, Incorrect tool number, Damaged or not loaded board. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after correcting data and removing tool to safe position. Resetting without fixing the cause first only hides the problem: Siemens 50010 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 TOOL.T and the offsets, Check active tool/magazine, Review program call. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Siemens 50010 active, avoid this: Do not load approximate correctors without measuring tools, Do not continue if Z is not verified. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If the table does not save data or warehouse memory/PLC errors appear. 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. Tool management is highly dependent on ShopMill/ShopTurn/OEM.
