Thread: Tree J325 problem- Y axis faults problem

I have a J325 1990yr model. Delta 20 contol.

I can reference all the axis. Afterwards the X and Z move in the correct direction according to the control. The Y axis on the otherhand, when reference moves only toward the column or in the negative direction. I am not very far away from the column so i dont move it far in fear of breaking or damaging anything. When I try to move in in the postive direction( or bring the the table out futher on the knee) I get a y axis fault.

Is there a setting that needs to be changed to get it to function properly? It almost seems as if one of the parameter needs to be changed for direction or a soft parameter needs to have the numbers changed.

I should add, I just recieved this mill, and got it hooked up. So still getting familiar with the control.

Thanks for anyhelp.


And here are some pics

Sounds to me like a bad servo amp, but then I'm just a machinist with limited elec. knowledge

It's posible to be a limiter of end of course blocked. I had a similar problem with a Z axis for a lathe.

That machine is supossed to reference the Y axis as far out on the knee as possible, opposite of your present position(As close as you can get to matching up the little arrow on the end of the knee). It should flash "Fault" until all axis are referenced.

My Tree 325 has Hard Travel limits via switches(I have heard of some that dont have them though). But on my machine the "Soft" travel limits are set by you when you reference the machine. Are you sure your not on one of the Hard switches? Your pretty damn close there. You might have to take the cover off the Y aixs servo and manually turn it by hand to get it off the switch. Then slowly rapid towards the opposite direction to reference the y axis out on the end of the knee(Use speed "1" once you get it off the switch).

On edit, i can see your x axis hard travel limit switches in one of your pictures. I've never had my table that close, i wouldnt doubt your on a switch there.

I am going to try and move it manually. I have actually removed the y limit switch that it was on at that point. It will move both ways when referenced, just when I try to move it further away from the column, it faults.

Fixed. Moved it manually and was able to reference to where it should be. I believe what happened, was that it was ref'd to the wrong direction, hit the limit and thought it was where it should have been. Now on to the next problem.

Toolmaker. I know this machine pretty well, inbox me if you ever get stuck and i'll give you my Phone#.

Also, you always want to "home" the machine before shutdown. After your home, move each axis in the negative direction by .05" i believe(That should be the "6" button, hit each axis negative five times. Then shutdown.). Then on start up, just reference each axis in the positive direction and you will be in the exact same "home" from the last shut down.

Ally,

Thank you for the offer. Will probably end taking you up on it.

The machine I bought, was taken care of pretty well. I just need to get familiar with the way this control wants to work. So used to Fanuc/Yasnac based controls for the last 8yrs. The only other conversationla I have ran here lately is a Milltronics so, just need to get my mind straight with this one.

Plus I need to look thru all the paperwork that came with it. Have just about all schematics on the electrical side, I was surprised. It originally was sold to somewhere in Cali, and ended up 2 hrs away from me where I picked it up.
