Hi
Boy do i need help
I am working on my bridgeport vmc760 with heidenhain tnc 2500c control that has lost all parameters due to battery failure and i have no manuals to assist me.I am looking for a parameter list to bring this back plus details on how to reset/reteach its reference points and the code number to allow axis movement in manual mode.
thanks poss31

sorry there doesn't seem to be one on the site. I bumped my old parameter thread up. I would hope others would post their parameters.

Once you do get parameters, you will have to set the end of travel points as well as tool change height yourself.

I believe I read that the 2500 is bridgeport only version of the tnc360. You could go to the heidenhain website and download control manuals there.

The relatively 'modern' heidenhain controls use the same parameter numbers for the various items, so the list I had posted for the 410 would be a decent start for the 2500, but many, many things would be different.

As Gus said,you can download the manuals from Heidenhains site.Each parameter for the control will be listed and explained but you need to know what you`re doing to work out what to enter on the control.
If you have a toolchanger you may actually have to know a specific parameter for certain ones which are linked to the plc and you could spend the rest of your life trying things.
As you`re in Scotland I`ll have a look and see what I`ve got,failing that you want to speak to Jack Robertson at Robertson Machine Tools (or something similar) in Whitburn.
Whereabouts are you?

EDit: If you go to the Heidenhain site and download the manuals and read them you will find the various codes to let you work with the control.When you find the code to let you jog the axis to set software limits be very careful how you use it.

Poss31,

In the past I have contacted the Hardinge UK office, they are the old Bridgeport. They used to do all the engineering there. Ask for Sean Briars or Darren Clarke both good guys. I once helped a guy in India thru the UK office with parameters on a vertical with a pallet changer.

They should have a parameters list if you provide the serial #.

Jack Robertson is the official Bridgeport agent for Scotland.
The second best bet is Ali Hoder from AL Machine Tools in Birmingham.Ali is ex Bridgeport technical service.He has parameter lists and PLC programmes for nearly every cnc Bridgeport ever made.
They are both very helpful guys.
Mark.

thanks for your replies lads i did manage to get a parameter list but i cannot get the machine to move in manual it still wants to reference.The code number i am trying is 84159.
gridley 51 i am in sunny Irvine.

Hi guys My machine is a VMC 760 with control TNC 2500 B, the TNC presents the list of machine parameters after the memory test.
I entered by hand on the keyboard the parameters, when i turn off and after turn on the machine, the lost parameters again, the battery is ok, Whats is my problem? what am i doing wrong?

[gus]

now, download the parameters, then post them in the parameter thread so the next time someone else will have them

parameter list for TNC 2500C
NC software 260010-05
PLC software 250144-08

Please, I want this version TNC 2500
NC 260010 01
PLC 250144 08

[Salah7701]

parameter list for TNC 2500C
NC software 260010-05
PLC software 250144-08

What do I write in the blank spaces like line 4210.0

Have same problem on a Bridgeport Interact 1 MK2 with TNC 2500c (NC software 260010 11, PLC software 250144 14). Lost parameters due to defective batteries over a weekend. Managed to get some parameter lists of similar machines but when trying to traverse reference points, keep getting a "gross positioning error Y D" even though X should be moved first. Is there a particular parameter that I should check that could be causing this problem?

[gus]

the batteries are no ok

could be that the contacts are bad from previous corroded batteries

Try hitting "end" after loading the parameters and before you power down.

Problem with Bridgebort VMC 760/20 machine:
When I press the oil button and then the start button, the start button does not work, but I hear the sound of the connecter, but the machine does not move and does not respond
