I followed the procedure until I got to the hidden parameter pages and I came across 3 pages that I didn't have parameters for. I had to change my backup batteries and reinitialize my control using the Mazak 0989-002 bulletin. I also own a 1986 QT10N but I have the T2 control no ATC just a standard 2 axis lathe. This is my 1st post but I have been an avid reader of Practical Machinist for a while now and I have enjoyed the many forums especially any and all Mazak CNC lathe information I just finished reading a post about the lost parameters on a 1986 QT10 T3 and I have a question about the "hidden parameters" in the machine. I could order a spindle temp sensor and see if it clears it, but it is hard to believe that all in a sudden the sensor goes bad without the machine even running. The PLC wouldn't recognize any of these inputs. I built jumpers with different resistance values in case the PLC is using a resistance value from the spindle sensor.Īnd then I connected a thermocouple to it and produced from 0 V to 10 mV going up slowly in. I measured the resistance of the sensor and it is 52.8 K. Non of my alarm lists give me 370 nor 371 to trouble shoot. Jumping the sensor gives me a "371 cannot start, spindle not warm" error. Register parameters that have to do with spindle thermal displacement are all in the not even close to the 2100-2009 that I checked and adjusted for the pallet changer and rotary table options. The spindle wasn't even running for 2 weeks. Upon repositioning and adjusting of the 6 pallet changer and after everything was ready to go, I all in a sudden received a 370 spindle over heat error. I thought I already posted this a couple of days ago. If you are here because you google searched these error messages on your display screen. I had no idea about this before today and it is definately NOT in the chapter of the Mazak book that I read. for someone like me with little/no experience. While this may be an every day common sense thing for 99% of you all. Once the tool was above the pipe, I was able to take my finger off of the middle button, press the reset button and everything cleared out. I pressed the jog button (10x speed) and flipped the toggle switch to X axis and began spinning the control wheel clockwise moving the tool up by hand. Once the screen came online I released my finger from the reset button and continued to hold it on the middle button. Now I hit the on button located on the monitor. Next I pressed down and held the reset button and the button right below it.

I did a full power down on the machine, waited a couple minutes for all the capacitors to drain and hamsters to fall asleep and then powered back up on the main disconnect. The reset will not clear until the tool is moved but I can't move the tool until the reset is clear! So now we are in an interesting position. this was not going to reset until the tool arm was above the pipe. an operator over extended the tool (pictured below) The alarm book did not provide the solution I needed, however, the solution was found and I want to share it incase anyone else might find themselves in such a position.īasically. I came into work today and the Mazak was down (again) with two errors.Įrror 121 Overtravel and 023 Illegal memory 1.
