PLEASE provide the colors you have...that would sure help......
There is a picture of of the cable with all cable colors. Thanks for this info but still not unclear. Should I connect together brown/green and blue together for +5v white/green and white together to gnd? If so what about those two extra violet and yellow wire?
Do your wire colors match the chart you provided? (Says incremental signals on top of the page, you just posted it)
Do a little work, write down your current cable colors COMING OUT OF THE ENCODER (if spliced to a home run cable, they colors may change in the home run cable to the control)
Then match them up with the signal assignment.

Here....maybe this helps:

The colors match to hidenhain diagram. I already posted photo of my cable with all wires visible there.. i’m posting it again. This is what still unclear to me. Should I connect together brown/green and blue together for +5v white/green and white together to gnd? If so what about those two extra violet and yellow wires?

I took the time and did it for you. Study it. Your responsibility to double check it
Note, I believe that +5V wires and COM wires are tied internally in the encoder. You need to verify this

Thank you very much... really appreciate that. Everything was clear to me apart from those com, +5V and those two unused wires. I will check if those +5V and com are wired up together in encoder even though I didn’t want to open it. I will then wire them up together in end DB9 connector. Those two unused I will only isolate inside the connector. Once again thank you for your great help. I’ll come back here with result

Once verified, wire up one encoder, double check your wiring, then go into the PID menu as instructed in the installation guide and test the one encoder to see if it's feeding back properly. If you slowly rotate the motor shaft, you'll see an asterisk blink indicating the Z index pulse was detected

My Heidenhain encoder works like a charm. Thank you all for your help with this one 😉

Hi All,

I am using a Heidenhain ERN 1120 on my spindle motor, as that is what came with my CTEK VMC.

According to the data sheet, that I found and already posted here, the ERN requires a grey wire for the B channel.

Problem is I don't have a gray wire out of the encoder!

I have

Blue
Yellow
Brown
Green
Pink
Red
Black
White

Any suggestions?

Thanks
Charles

Instead of highjacking an old thread, you might get a better response if you started your own thread topic, especially as this one has been marked (Resolved)

You might try searching for other Heidenhain encoder datasheets and comparing their wire colors with yours and see if you can find a match.

You could assume red/black are +5V/gnd and use a tester like this: https://www.quantumdev.com/build-your-o ... ck-tester/ to identify the other leads.
Cheers,

Tom
