Haas 100 alarm: Machine not referenced at boot

Haas detects that the machine did not complete zero return upon power-up or after an alarm. It is an alarm from the Sobrecarrera area, and in the catalog it is listed as “Machine not referenced at boot”. On the machine you notice it like this: It doesn't let you enter automatic, Pide Power Up/Restart, Occurs at the start of the shift.

On the shop floor it almost always comes from one of these causes: Recently powered up without homing, Previous servo alarm, Apertura de puerta durante homing, Reference loss. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Completar Power Up/Restart antes de operar. Resetting without fixing the cause first only hides the problem: Haas 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: Check area free of obstacles, Execute Power Up/Restart with caution, Check that no axis is stuck to the limit. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Haas 100 active, avoid this: Do not start cycle without homing completed, Do not skip the reference sequence. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If it does not complete homing or it hangs on some axis. 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.
