Mitsubishi M01 0006/0007 alarm: Hardware/software stroke end

Mitsubishi detects physical limit switch or software limit reached. It is an alarm from the Sobrecarrera area, and in the catalog it is listed as “Hardware/software stroke end”. On the machine you notice it like this: Axis at limit, Does not allow movement in one direction, Stroke end alarm.

On the shop floor it almost always comes from one of these causes: Offset incorrecto, Out-of-career program, Active limit sensor, Soft limit parameter. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after freeing the axis and correcting the cause. Resetting without fixing the cause first only hides the problem: Mitsubishi M01 0006/0007 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: Identify axis and type of limit, Leave in a safe direction, Check the origin and the offsets. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Mitsubishi M01 0006/0007 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 limit does not release or there is damaged sensor. 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.
