    Default Fadal vmc 15xt losing parameters and what to look for purchasing

    So if found a decent deal on VMC 15xt with 88hs control. The only issue is the control will not hold the parameters (whatever they are??) according to the seller. Now i know very little about these industrial machines and don't actually know what the parameters i have to reset would be? is there like a list of machine travels i would need to know? I do know how to run a cold start on the machine and it is under power for viewing.

    I am currently stationed in California so my dad is going down to look at the machine on Wednesday and ill get an update on it. Is there anything specifically he should check out on the machine? The owner said that the axis do all jog but like stated will not hold parameters. Also how easy are these to move we have a 5k lift with 4ft forks but im thinking that wont lift it so we might rent a forklift and drop it on my dads trailer and then it will just be interesting getting it off with the small lift.


    Some machine specifications if it helps.
    1999 Fadal Vmc 15xt
    88HS control
    7500 rpm spindle
    10hp spindle (owner says its single phase?) I assume no rigid tap.

    in the end im hoping to have a affordable small machine that i will be satisfied with and get rid of my excello 602 cnc "project"

    My 1st guess would be the battery is dead. Does it hold parameters as long as the power is on, then when powered off parameters need to be reset next power on. Battery is easy to replace with a little soldering skills.

    That was my first guess too but the seller made it sound as though it lost everything while on. But if it’s only when it’s off then I suspect the battery and capacitor are dead. This makes sense because the machine didn’t run for a while.

    The Fadal 88HS control has 3 short pages that you manually input the parameters. There is a sheet that is usually stored in the cabinet that has all that information recorded. If not, you can usually figure it out with a knowledgable Fadal tech. You'll also need to reload the backlash values.
    Plenty of places online that have PDF of Fadal Manuals.
    That mill weighs 5,500lbs and 4 foot forks won't get you there. Hiring a rigger would be money well spent in my opinion.

    Yea I think we may rent a forklift if I end up getting the machine. That’s just another expense I can barely afford. Thanks for your help so far. Hopefully those pages will be I. The cabinet.

    If it loses parameters and is now running, it sounds at least you have the copy of them.
    Otherwise it would be a white Elephant!
    BTW, you can change the batteries while the power is on.

    Yea I’m not really understanding therefore why gonna have to go look at it.


    He says this machine is single phase too so that’s a plus because currently I’m running off a phase converter.

    Lost parameters arn't a problem on a Fadal with 88HS so don't get too worried if you don't have a back-up. By the way,sometimes Fadal would also have a sticker in the monitor compartment that had them recorded.
    The battery is soldered to the main board and must be removed to be replaced. They usually last a looooong time though. I have Fadals from the late 90's that still have the original batteries.
    That machine was offered from the factory with a single phase transformer so if you got one, that's a big bonus. They had a pin to put into the Z counterweight for shipping. If you don't have it,make sure you run the Z head down and afix it to a block of wood before shipping.

    Parameters are not a problem on the Fadals very easy, basically answer questions. Majority of 15's with 7500 rpm have rigid tapping so most likely you have it. There is a sticker or card with the original Parameters. Will say rigid tap. Also in Manual data type G84.2 and it will spin calibrate and then hold the spindle rock solid in position. Attached is your Parts Manual https://itscnc.com/images/VMC_15_15XT.pdf you can download lots of other manuals too very useful all FREE, Never pay for a Fadal Manual (like on Ebay)

    Pretty sure the Machine is closer to 7,000 pounds but anyways the VMC 15's have pockets (square tubing front to back) specifically there for your Forks. Makes it very safe to move. As long as the Forklift is rated to lift the weight. 5k forklift will be dangerous. But good luck. I have 9 Fadals oldest is 1984 but check out the finish on our 1986 4020

    Good thing the 15xt is 1999 cause it has waylube pump not grease fittings. I also have a 15xt cuts great we make Cast iron Housings and it can push a 2" spade drill 300rpm feed 2in. with no pilot hole. No problem.

    If you have any questions give me a call

    BTW, you cannot change the battery while the Fadal is on. Losing your Parameters on a Fanuc or basically any other machine can be a very serious problem if you dont have a back-up. Losing your parameters on a Fadal is a 5 minute inconvenience. Just type SETP and answer the basic questions some of the questions even give you a hint to what the answer is, lol . And many of them are factory answered some get slightly adjusted for tuning.

    Well thanks so far for the help. Once powered on the machine worked fine although the toolchanger dropped a tool. The parameter where all in and the machine works. There is about .02” backlash in the y but the screw looks good. Also missing a z axis way cover so I’ll have to find it. Pretty sure I’ll be purchasing it.

    Factory wired for single phase btw and 1 owner machine.


    Does anybody know how to exit diagnostics mode? I tried x but nothing? Ended up just shutting off the machine and re cold starting.
