Heidenhain Tool not in table alarm: Tool not found in table

The TNC rejects a tool call because the number does not exist or is not active in the table. It is an alarm from the Tool change / ATC area, and in the catalog it is listed as “Tool not found in table”. On the machine you notice it like this: Falla en TOOL CALL, Appears after deleting/editing the table, Program asking for tool not loaded.

On the shop floor it almost always comes from one of these causes: Tool not created in TOOL.T, Wrong tool number, Magazine table not synchronized, Tool not enabled. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after loading/correcting tool. Resetting without fixing the cause first only hides the problem: Heidenhain Tool not in table 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: Open TOOL.T and verify number, Check magazine table, Load tool before TOOL CALL. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Heidenhain Tool not in table active, avoid this: Do not start cycle without a verified tool, Do not edit table with active cycle. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If the table loses data without cause or the magazine does not synchronize. 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.
