Haas 102 alarm: Servos off

Haas indicates that the servos are disabled or not ready. It is an alarm from the Servo / ejes area, and in the catalog it is listed as “Servos off”. On the machine you notice it like this: The axes do not move, Servos off en pantalla, It may appear after an emergency or previous alarm.

On the shop floor it almost always comes from one of these causes: E-stop activo, Previous servo alarm, Puerta/interlock, Servo power failure. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Clear the cause and run the normal power-up sequence. Resetting without fixing the cause first only hides the problem: Haas 102 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 the e-stop, the doors and any previous alarms, Try Power Up/Restart if appropriate, Check that there is no axis in limit. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Haas 102 active, avoid this: Do not bypass safety devices, Do not manipulate energized electrical cabinet, Do not continue producing if the alarm reappears. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If the servos do not enable after releasing the safety and a normal restart. 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.
