Mitsubishi L01 alarm: Lubrication alarm

Mitsubishi/MELDAS detects lubrication problem (level, pressure or pump). It is an alarm from the Lubrication area, and in the catalog it is listed as “Lubrication alarm”. On the machine you notice it like this: Lube alarm, Pump does not deliver pressure, Risk for guides.

On the shop floor it almost always comes from one of these causes: Nivel bajo, Damaged pump, Clogged line, Pressure sensor. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after confirming lubrication. Resetting without fixing the cause first only hides the problem: Mitsubishi L01 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 level and that the oil is correct, Look for leaks, Do not produce without confirmed lubrication. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Mitsubishi L01 active, avoid this: Do not bypass the sensor, Do not machine with dry guides. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If pressure/flow is not recovered. 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 critical: there is a real risk of damage to the machine, the tool or a person. Leave the machine stopped, do not keep resetting it to see if it goes away, and call maintenance before producing again. Guidance reference. Always confirm the full text in the exact machine/control manual.
