Never reloaded or had this running here...I did get these on startup
11 Battery fault
12 Batttery fault
After clearing it was fine untill I tried to jog and then the Z axis went the wrong way and gave me the travel error and wont jog back (joystick) and X wont move either.
It definitely looks like parameters, do you have a hardcopy, it will be easy to compare, If you do not have, I may have a copy that will be close.

I have a hard copy sheet that explains the input of the parameters (default)...but I think it only covers the first page of them.
You should have the parameters, inc options, tool offsets and chuck barrier data.
See if these still exist at least, and copy down.
You should have got the copy from the previous owner.
There is a procedure for clearing memory and entering the data, the OP parameters have to be entered with a 9th parity bit.

Plain english on that last part please
I can put together something for the procedure for clearing memory and re-entering all, You will need the original list of parameters and options.
I may have one from a similar T1.
The OP parameters are entered as 9 bits, e.g. if the parameter is 10101001
then it will be entered as 101010014 (4 bits set to 1).

Al I have the parameter worksheet for the tooling offsets like shown here but I dont have any other worksheets for the machine. I will check all mauals
MAZAK QT10 T1 55 ALARM
HI,
I HAVE A MAZAK QT10 TI,I AM GETTING FRQUENTLY 55 SPINDLE OVERLOAD
ERROR.WHEN I SHUT DOWN AND RESTART THEN THE MACHINE STARTS AGAIN.
WHEN I CHECKED THE ERROR DETECT LED IN SPINDLE DRIVE IT SHOWS LED 12 AND 13 IS ON.
THE COVER SHOWS IT IS INVERTER IOC ERROR.
I NOTICED ONE OF MY SPINDLE DRIVE FAN NOT WORKING EVEN WHEN THE MACHINE IS WORKING.
CAN YOU HELP ME HOW TO FIX THE 55 ERROR.

Hello,
we have a similar problem - so i wont start another topic.
mazak qt10 with T1 and Freqrol FR-SX.
when we power it up we have alarm 55 spindle overload.
leds no 5, 10, 12 and 13 are on - says inverter over current.
i checked already thyristor and transistor units on power board. there is no shortage on them.
but then on the left side, a bit lower on the control board there is a row of leds and we have three leds light up. numbers with leds are 101, 102 & 103.
is anyone possible to say what is the meaning of the leds 101 till 103 ?? maybe they say what is the reason of my problem.
thanks for the help
Did you check the breaker for the drive, usually mounted behind the swing out door on the drive.

yes, breaker is ON condition.
I am so glad I found this thread. I also have Mazak QT 10 that sat for some time and has an identical problem. When powered on I generally get
28 F Emergency Stop
55 Motor Overload
My machine had lost it's parameters when I first bought it about 2 years ago and thankfully Al had a copy and helped me reload them about a year ago. I still have the originals I can upload tomorrow. It's getting late in the day so I just wanted to recap what my machine is doing to maybe help others troubleshoot.
But here is what happens from the first thing each morning.
When powering on the machine in the morning for the first time I usually get alarms
11
12
Which are parameter faults. I check my parameters and it actually still has the ones I loaded in so it never *really* lost them. I then power it off and back on and the parameter alarms go away and I get the 28 and 55 alarms just like the others in this thread.
I get the 28 and 55 alarms mentioned above for about the first 4-6 hours of the day. I randomly keep going back to the machine and power it off from the front panel and then back on. usually the same two errors come up.
But then magically (maybe because the shop warms up) after that I can power it on and it FULLY WORKS for about 30 seconds to 5 minutes. For some reason it usually helps to index the turret first and the 28 alarm doesn't *seem* to come back on right away. I can Zero it out, run the spindle, do everything it should do. in fact one day I even had enough time to write a program in conversational and run it a couple times. But usually after 30 seconds to 5 minutes of no errors I get either a 28 F Emergency Stop or both the 28 and 55 alarms again. Then it is back to powering it off and back on until it magically clears itself again.
SO long story short here, I know my machine works (and I believe so does the others here who have the same alarms). It's just a matter of troubleshooting it down to what is causing the alarms. more to come tomorrow...

Mazak QT10 Parameter List and other useful info
I was burning the midnight oil tonight and figured I would type up the 3 pictures I had of the Mazak QT 10 (Quick Turn 10) parameter list to make it easier to read and print. I am attaching it here and will also have it available on our website for download. I am also making available some other useful info that helped me get my QT10 up and running to the point it is now. These parameters get me up and running, just not sure what is causing the 55 and 28 alarms. Like I mentioned though after the machine is on for a while the alarms disappear and i can use the machine for a few minutes before they pop back up.

barchdesigns,
Interesting issue you have, what you maybe describing is a supply voltage problem for the CNC. Since this is a T1 you have a power suppply located behind the main mother board LX51. Usually it has terminal screws or plastic connectors. Use a multimeter and check your dc voltages. 5v, 12v, -12v, and 24v, I'm really wondering if these voltages are good or not. Also you have a smaller power supply behind the operation panel that you should check also. Please let the forum know your results, even if they are a little off.
Regards,
Chippy
Regarding the Alarm 55 and Alarm 28, please take note that if parameter "SQ" is not set right, you can get some eronious alarms. This parameter turns on different PLC switches in your ladder which are linked to different machine configurations. It all depends how the machine is configured at the factory.
Regards,
Chippy
hello,
my case is solved - the service guy from mazak found it out in short time. they say its most popular damage to this drive type. below the control board there is one more board . this board contained an element covered with kind of glue (or plastic) - this one was damaged. machine works nice ;]
How much did that board with the glue or plastic cost to replace? Can you describe it in more detail to help me locate it? Mazak wants me to send in the whole FR-SX set of boards and charge $3,330 to repair it when I talked to them on the phone!!! Wow that's a lot of money.

I measured the voltages as you suggested. I was even lucky enough to be able to measure them when the machine was powered up with no alarms AND with the alarms soon afterThe voltage measurements were exactly the same however. Here are the results:
On the board behind the front control panel there is a power supply with an adjustable regulator pot.
"AC in" marked 100V, measured 100.3
"DC output" marked 5V, measured 5.04
And here are the results from the back of the machine measuring the power board behind the "Control Unit"
24, measured 24.2
5, measured 5.19
12, measured 11.99
-12, measured -12.01
Also my SQ parameter is set to 19993
I also measured the incoming AC 3 phase power before and after the main transformer in the back of the machine.
incoming voltage:
213
215
208
output from big transformer
225
224
224
So I called Mazak this morning and had them help me troubleshoot the alarms. The representative told me I need to send in the whole "AC Spindle Controller" FR-SX and that it will cost $3,330 to repair. He said it is probably some transistors that have gone bad. Seems awfully expensive!!!
Now I have dabbled in electronics for quite a few years and it seems that for a few hundred dollars I could desolder and replace every transistor on the boards and possibly solve the problem? Has anyone attempted something like this? Am correct in thinking this?
Here are a lot of pictures of the machine state now. Please help. What do you suggest I do?
