Thanks for the explanations, I begin to understand which parameters are exchanged between the tnc controller and the spindle drive.

In my case here is the wiring diagram from the maintenance manual

I can send you the original file if you give me your e-mail address, I had to take pictures as I don't have an a3 scanner, I hope that the quality is sufficient.

There is no toolchanger on this mill, it's a spindle with a QC40 nut, the power drawbar was an option. It's a bit sad, in the case of a retrofit I would have liked to build a toolchanger, there are probably very interesting things to learn in such a project!

Bridgeport show the KTK better than Beaver do.Beaver do not show the internal connections between the various cards.
I will send you a PM with my email address but I would urge you to replace the snubbing caps in the KTK drive and try it before retrofitting it.The caps are not expensive and the KTK is a good enough drive when it`s running.

Just a little update,

With the help of Gridley (which I thank a lot), we repaired the drive and it now works very well.
The problem was mostly due to the blown caps, for those who hesitate for a replacement of the RIFA (difficult to find) here is what I successfully replace them by:

-0,1 uF caps of the power board (THY-1R): Epcos B32653A7104J , they have higher specs than rifa's (500 vac and 1250vdc)
-0,022 uF cap of the MTI-1 board: Epcos B32652A7223J , higher specs too (same as above)
-33 ohms resistors of the power board: Welwyn W23 33R JI (10 watts)

Here is the link of the Maintenance Manual of the Bridgeport interact 4 series II, there are some wiring informations and fault finding which could be useful on other machines too.

Please give me the wiring diagram of contraves spindle drive with bridgeport intract 4 series 2.
