Interact 1 MK2 update and problems

[BrianP]

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.

[gus]

be reeeeeeeaaaaallllly specific.

[BrianP]

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

[gus]

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............

[BrianP]

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

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

[BrianP]

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.

[gus]

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.

[BrianP]

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?

[gus]

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

[machintek]

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.
