Hi everyone,
I just got an Interact Series 1 Mk2. In truth I've had it since August, but I was just able to get the power connected yesterday. I had to have it inspected because it didn't have CSA approval (In Canada that's important apparently). The gentleman who came to inspect was very knowledgeable, though at $153/hr, I'd expect that... but I digress.
I have seen several interacts and the axis drives looks as in the picture I have attached. Three (Bosch I think) servo drives and a large transformer for them in the bottom left.
My machine has 4 servo drivers, and an additional transformer in the middle of the bottom of the electrical box beside the big one. On the back of this box on my machine are 3 connectors. The first is quite large with 15 or so pins, and two smaller connectors with less pins, 3 or so. I can't be more exact as I'm not at the shop right now and won't be back there until Tuesday as I'm finishing exams and should be studying, though this is infinitely more interesting
The Heidenhain 155 I have will control a 4th axis. So now for the question.
Does anyone have any idea what the pinout for those plugs would be? The schematics I have for the machine don't show this 4th drive. I have several spare servo's as spare parts and would love to build a 4th axis. Usually I beleive the rotaional encoders for the 4th axis have 8000 steps /rev (from the heidenhain controller manual).
So to reiterate the question because I tend to ramble.... Has anyone seen a 4th axis on an interact Series 1 Mk 2? Does anyone know the pinouts at the back of the machine for the 4th axis?
My plan of attack should no one have the pinout is going to be check the back of teh TNC itself, trace those connection to the plugs, cross reference with the TNC schematics and try and work it out, but of course if it's available without having to do that, all the better.
Thanks for reading. I'll post pics of my board on Thursday or so when I get back to the shop. Any help would be greatly appreciated. Thanks again
