Hey guys I'm wondering if anyone here can help me. I have a 1990 Bridgeport Interact 308 VMC that im having some issues with. the first issue i had was the 24Vdc powersupply went bad. Ive fixed this problem but now the spindle will not orient itself for tool changes. when i run a tool change program the Z axis goes to the right height and then the spindle oscilattes back and forth.
this machine uses a Heidenhain tnc 2500 controller. any help here would be much appreciated

I know that the DX controled 308s had a KTK spindle drive. What does this one have?
Is the spindle speed accurate?

This one has a ControlTechniques Flux Vector Drive type V400.
I'm no sure how accurate the rpm are. I can check the rpms at a low speed
tomorrow and check them against the tachometer on the screen

Control Techniques did make the KTK drive but I am unfamiliar with the V400 designation. I will do some research when I get a chance to get by the office.
I questioned if the RPM was even close to see if there was a speed feedback issue.

I actually worked on an interact 308 today. Had to resurrect the parameters. The ETS is wrong in a few places. But with a list of parameter definitions, I managed to get it going.
Is there a way to get a copy of your parameters?
Could you fax it to 1-205-403-8900?
Or email them to me.
I see what you mean about the FLUX VECTOR DRIVE and the orient board just to the right. Bosch drives. And a very unusual place for the control.

George

Can you send a copy of the V400 and TNC 2500 parameters ?
