So I have been looking at the Kanalog pinouts and I have some questions. The JP6 Analog Input +/-10V is labeled 1-7 and the rest are ground. First off is that where I hook up my encoders or resolvers for the time being? Is the JP11 Output for my signal wires? For instance if I were to hook in my X axis signal wire would it be wired up as + to the #1 Terminal and my - to the first available ground?

I'm super new to this stuff. I realized just now that JP1/JP2 are for encoders so does that make JP6 for my tach?

Sorry for the dumb questions. Some added info. I have a mill with 3 Summit Dana DC brushed servo motors 90V, 7.4A, 1430 RPMs. I'm going to be wiring in a NC400 Amp.

Hi Matt,
 
It would have been helpful to include a link.  I Googled and found this:
 
 
You probably don't need to connect the Tachometer or use any ADC inputs.  Velocity can be derived from the encoder to stablize the loop if the encoder has good resolution.
 
Yes JP11 would be the DAC outputs going to your Amplifier.  The DAC outputs are single ended so yes use any Kanalog GND for the - input to your Amplifier.
 
Differential encoders would connect into JP1 or JP2
 
Regards
TK

I found out these encoders have a 5 week lead time but I would still like to move forward with the project. Is it possible to just use the resolvers until my encoders arrive? Are they wired up the same way? I started a new topic before I realized u responded again on here. It's titled signal wires.

Thanks for the help Tom.

Hi Matt,
 
No resolvers are totally different than encoders and are more complicated.  I don't think it makes sense for you to interface them if you plan on replacing them anyway.  See:
