Okuma NC-100 alarm: program error

The OSP control detects invalid command, format, or parameter in the program. It is an alarm from the Program area, and in the catalog it is listed as “program error”. On the machine you notice it like this: Failure to verify/execute a specific line, May appear after post-processing.

On the shop floor it almost always comes from one of these causes: Code not supported in OSP, Incorrect cycle parameter, Formato G/M incompatible. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after correcting the program and returning to a safe point. Resetting without fixing the cause first only hides the problem: Okuma NC-100 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: Note the exact block, Verificar manual OSP, Revisar postprocesador. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Okuma NC-100 active, avoid this: Do not delete blocks without understanding the strategy, Do not continue from the middle without checking manners. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If the control rejects valid programs or there is a memory fault. 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. Use exact generation OSP manual.
