    Interact 1 MK2 update and problems

    I had posted earlier about loosing the parameters and then I had a 24 volt power supply go out. I replaced the power supply now I have a whole new set of problems.
    When I power the machine up I can get the axis's to zero, or at least they appear to, but am unable to get it to do anything else.
    I can't get the power feed or handwheel to work, the spindle will not come on and most of the buttons are non functional, or at least that is the message I am getting.

    Any ideas?

    I forgot to add what do the 2 air fittings beside the left hand side of the column go too, I can't find any reference to them in the manuals.

    Please explain as to the specifics needed, I will gladly try to explain or detail anything I can.

    precisely what does it do or not do, do the xy andz disappear from the screen, do you get error messages, are you able to move between modes[ie manual, programming etc] will it respond in every way except moving............

    When zeroing the axis's it goes through z,y and x, on the x it faults out on the limit switch but I am able to hold the CE button in and get it off the switch.
    When the top of the screen says manual operation the lower half says actl : x,y,z

    When I attempt to manually start the spindle I can enter tool speed and the M03 but when I try to start it I get the message SPINDLE DRIVE FAULT.

    It seems as though most of the lower right hand keys(block of 10) give me the correct message when pushed except for the P and I key, which give me the message non functional.

    It is hard to say which keys are working properly as I assume it depends on what I am doing as to whether they are functional.

    Going through things I found this information on the screen,
    NC SOFTWARE NUMBER 243000 12
    PLC SOFTWARE NUMBER 250144 03

    I opened the left hand cabinet and when I pressed the large red reset button a red led went out in the center of the board and a larger red led near the bottom center came on and the spindle turned briefly, then things went back as before.

    Please let me know if there is anything specific I should try or any specific information you need, MANY THANKS

    re

    The x axis might be a parameter that needs adjustment, or maybe the trip dog switch is not functioning

    You know you have 24v to the control since it is not giving the ext ref voltage error, but perhaps another fuse is blown.

    So the machine will not manually traverse? Will it traverse in MDI or Program run with no spindle on commands?


    Could actually be a drive fault

    The machine moves fine when it is zeroing out, all axis's move in both directions, but only while zeroing. Once it is zeroed and I go into manual mode and try to use either the handwheel or tooggle's nothing happens.

    I am including another picture, are these all fuses? only a few of the red LED's light up, I have checked everything else I could find to see if they were tripped or not.

    Thanks

    I just noticed this, when the machine powers up the screen says memory check, if I wait the message changes to power interrupted. The machine will still zero though.
    Also the LED 12(?)INS TRIP is lit, when I press the reset button in the left cabinet the LED goes out, LED's 2 & 3 then come on momentarily as the spindle starts to move, LED 2 & 3 then go out and LED 12 comes back on.

    re

    Those are relays. The leds show their state, so some will be on some will not, depending on lots of things

    >>>So the machine will not manually traverse? Will it traverse in MDI or Program run with no spindle on commands?<<<

    one question answered, two to go


    On my older series interact, the small fuses are in little screw type holders.

    FU is a FUse

    CR is a Control Relay

    There are also large contactors and a few other devices.

    They mostly all do a memory test first, you just never noticed.

    I can't get it to move with MDI or program run either.

    I found three of the screw cap fuse holders and the fuses appeared fine, I'll double check them though.

    What would be causing the power interrupt message during start up?

    re

    'power interrupted' is the appropriate thing, since the power was, umm interrupted.

    power interrupted = power was off wasn't it.

    If the machine homes, you are 95 percent of the way there, meaning that the control and drives are working.

    If you go to want to use the handwheel, you need to select that, select an axis and select the interpolation factor. (how fast or slow it will go when cranking the handwheel a given amount).

    If your travel limits were messed with, you should get a soft travel limit alarm.

    Do you have the operating manual? The rest of the manuals?

    Maybe to feed with the joystick, the spindle must be on. To feed in rapid, you need to be in manual mode and press the center button in the joystick.

    When i got the power interrupted message i am assuming the power was off somewhere but as soon as I pressed an axis key the machine went into "homing mode".

    I tried that with the handwheel and I still did not get any movement on any axis.

    I tried to use the joystick like that and there was no "joy", nothing moved.

    I have some of the manuals, I contacted Heidenhein and they gave me the following information:
    The TNC2500 is a custom made control for Bridgeport it is base off our TNC 360. The records for the machine (including the machine parameters) should be available at the Bridgeport UK (England) facility.

    Oh yeah, is there oil in it?

    The oil tank appears to be half full.

    I am still wondering about the air fittings on the left side of the machine near the column, there was nothing hooked to them and when I supplied air to the machine air just rushed out so I took the fittings out and put plugs in there place. Are they suppose to be hooked up to something?


    I also noticed when I wired the machine up that the tag said it was wired for 220/230, but someone wrote on the side panel in marker that it was wired for 440 but when I checked out the transformer it was actually wired up for 210. Since it came out of an older school I am assuming the building was wired for 210. The thing is there was another wire that was switched at some point from the original setup as you could plainly see where the factory had it wired originally, I moved it back to this original position, did I goof? here is a picture of the wire.

    re

    PICS.............

    The old ones [with varispeed head] frequently had a indexer attachment with a pair of air lines, but they don't leak air. What kind of tooling, power drawbar?

    no power draw bar, it uses taper 30 holders, here is a picture. The air fittings are just to the right of the light base.

    Had a friend over today to help me look at it, well we messed something up I guess. I showed him how the machine zeroed out okay and what happens when I press the reset button as far the spindle moving goes.
    We were going through the various buttons trying to get something to happen, I guess it did and not for the good.
    When I power the machine down now and try to restart it I get the following messages as before, Memory check, power interrupted. The problem now is when I use to press an axis key the machine went into a homing cycle, now I get the word DIST. displayed and the x,y and z screen does not come up and the machine does not zero any longer.

    We were able to find a total of 7 fuses, all of them checked out okay.

    Does anyone know of someone in my area that can help out, thanks Brian.

    re

    DIST is distance from reference marks, one of the available views [actual, distance, nominal, lag]

    Is the machine enabling? look for lights on the servo amps

    Please remember I am a neophyte when it comes to electronics, what do you mean by enabling and what/where are the lights/servo amps? sorry if I am dumb on this but unfortunately I am.

    re

    You need to get manuals. The Heidenhain manuals can be got at their website. The interact manual try ebay.

    The button you hit after the 'CE' button and before you hoe the machine is the 'power enable' button. It enables a self holding relay, which is what pops out if you hit the EMO button [big red button]


    There will be 3 servo amps in the power enclosure, and they should have some sort of LEDs on them, 2 green if they are Bosch amps, prior to being homed, IIRC

    again, get the manuals or you are just going to struggle and get frustrated and I am just going to yell at you.
