No matter where/how it's stuck, look at where it's stuck relative to the order of operation and move forward from there. It's a simple matter of 'order of operation'. The best way to get familiar is to go through a tool change cycle using the Maintenance page from start to finish (you'll also need to use the Tool Clamp/Unclamp button midway). I can clear any ATC alarm in seconds (unless something mechanically very bad happened). Get famililar with the ATC Maintenance page. The quick way to clear the alarm is to simply satisfy the ATC condition for where you got it stuck at. It is SO gosh-darn frustrating!! Please help!!

It is not just limited to one model or version of Mazak CNC mill as it has occurred exactly the same on several different model Mazak mills. I would SO GREATLY APPRECIATE it if ANYONE here can PLEASE tell me the specific and correct way to clear this alarm on the Mazak CNC mills. Now I know that the ultimate solution is to NOT push the "Reset" button during a tool change, but sometimes instinctive reactions take control and I then get stuck with 20 minutes of time wasting and lots of cussing to clear this alarm which I (and others) clear only through random button pushing to which finally hitting the magical combination of buttons to clear it. The alarm occurs when an operator presses the "Reset" button while the machine is in the process of performing a tool change.įor myself and many others, hitting the "Reset" button is an immediate and instinctive reaction to the realization that there may be a problem somewhere or that the program or other data may have been inputted incorrectly to which it is necessary that the machines operation be terminated quickly from running.

The following is my post from about 2 yrs. (Japanese English = "Jenglish") The sequence is accurate, but understanding which keys to press and how to find them is confusing.Įssentially, you unclamp the turret, rotate to the #1 position, and store that encoder reading as the reference position.

There's a recovery procedure in the Maintenance Manual (in this case, for the Mazak Quick Turn 350 / Manual No. You've lost the reference (#1) position of the turret and must re-estabish it.
