I have a encoder that only has the pin outs for A and Z but the ENC asks for A,B and I from this should I assume that the encoder needs replacing if so will one with the out puts of A,B and Z fill my needs because this is all I can find and if so will the Z out put be my I. Because I have never used or played with encoders there is little understanding of what is needed for this to work.
As a note this is a Denford lathe and they like to do odd things like with the limit switch's being what they are so I'd not be surprised if I need to replace the encoder
The other one that is doing me is the Inputs to the IP-S for the variable speed control for my inverter what out of +10V, MVI and 0V goes in to what inputs, the over ride pots are working because there was a diagram for me to follow. One thing I have done right or wrong is that my inverter use's 12V to the switching and so I have run 12V from the inverter to the out put's of the IP-S to power it, the inverter will take external 24V supply for the switching but then I need to use the 0V for grounding and until I can understand how I wire in the varibel speed I cant do this because it uses the 0V as a return to the external power supply.
Hope this is readable and some body can help

What lathe is it?
If you check out my Cyclone build thread on here, you'll find a post about how I was able to solder in the extra wires to get the B signal.
Have you searched over on the Denford forum for wiring diagrams?

The lathe is the Mirac with a ATC I would very much like to see your build I have been unable to find your build could you supplie me a link please.
I do have a diagram for the machine but I don't know how to take from it what I need to make this work.

This link should take you to the first of the posts covering the encoder - http://www.machsupport.com/forum/index.php/topic,25493.msg181866.html#msg181866
I thought I had a photo of the encoder internals, however I can't find it in my photo collection.

If you've not had any joy with the encoder yet, I just so happened to browse a thread where I'd seen the details of the encoder previously (I knew I'd seen photos somewhere!) - http://www.cnczone.com/forums/benchtop-machines/261754-cnc-post1775234.html#post1775234 should take you to the post containing details for the encoder.
