Need Help!- VMC 1050 won't move any axes

[puds]

We received a 1993 Tree VMC-1050 from a local company, donated to our high school shop. The machine worked fine prior to us receiving it (I verified) but once it was delivered, we had to have a bunch of breakers switched to be CSA certified for safety reasons (mandatory for ESA). All of the work was completed, and now I cannot get the machine to move any axis in jog mode to begin to reference the machine. Myself and the electrician have been over the electrical a bunch of times and can't seem to figure it out. The only fault message I have on the screen is Axes need to be referenced. The procedure I have used so far has been this:

1. Turn on power
2. Press Reset and then pressed start button
3. Select JOG from menu and 1 or 2 for slow or medium continuous jog
4. Have tried to toggle X, Y & Z axes + and - directions, and all instances give me the same issue. Nothing moves and the control gives me the error message blinking screen. When I go to the fault screen, all that is on there is Axes need to be referenced. ANY IDEAS?? I want to get this thing up and running! Thanks for any help.

manualy push the home switches to see if that clears the error code ... if it does re-home the machine ... make sure you aren't on a limit switch

The dreaded 1050. Most likely cause is the magazine (tool drum) in not in the rear or home position.

Second is no air pressure.

Did you here the machine kick on when you hit start. Should hear contactors latch in. If you didn't, an axis may be on a limit. there are small "doors" you put a long wrench in to and turn the axis off the limit with the wrench.

I think you should look into the ATC home position signal, if the ATC home position not made than all three axis can't be move

What is the ATC home signal?

[avtechmachine]

It is an automatic tool changer home position
is your VMC with ATC?

Tree had changed the proms on most of the machines to automatically drive the magazine home once you hit start on power up. If not, you need to manually activate the air solenoids to bring it back. They are right above the actual tool magazine, very easy to get to.

Before powering up open the left side door and manually cycle the the little white lever 90 degrees and turn it back. There are two "levers" above the magazine on the pneumatic assembly.
Cycle the upper one.
The magazine should "clunk" back to home position.
Power up main power. Power on control. power on again(energizes servos).
You should be good to go.
Also check way lube level- machine won't budge when low.
Wont budge if you power up overtraveled either.

Tried/checked all things and still the same. Machine powers up (latches) on start button push, tried cycling the pneumatic valves for the tool changer cylinder and still nothing. Still the same two errors:

1. Axes need to be referenced
2. Magazine # 1 not referenced

HELP!

Try going to the jog page, going to ref return, then hit cycle start. That should pull the ATC back, start the axis homing sequence, then the magazine sequence. If you here it latch on, it's not in overtravel.

Tried it and as soon as I hit cycle start, it flashed the error screen and showed me the same two faults again. The tool changer does appear to be all the way back and the switch is activated on the top of the unit (roller style limit switch).

Is the feedrate overide knob turned up ?
