Okuma B-2362 alarm: G40 only allowed in G00/G01

Okuma OSP rejects a G40 (cancel radio offset) in mode other than G00/G01. It is an alarm from the Program area, and in the catalog it is listed as “G40 only allowed in G00/G01”. On the machine you notice it like this: Falla en bloque G40, Aparece tras G02/G03, Program stops on compensation cancellation.

On the shop floor it almost always comes from one of these causes: G40 dentro de G02/G03, Wrong post-processor, Edition that breaks the sequence. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset tras corregir secuencia. Resetting without fixing the cause first only hides the problem: Okuma B-2362 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: Move G40 to a block with G00/G01, Review compensation sequence, Validar postprocesador. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Okuma B-2362 active, avoid this: Do not quietly delete G40, Don't edit compensation without understanding. Skipping any of these points is what turns a minor stop into an expensive breakdown.

Normally requires no maintenance. 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.
