Hi, everyone just getting an ALLIN1DC SET UP.
I have run into a problem with encoder differential errors on x y and z axis.
I have double checked my wiring and will be looking with an o'scope tomorrow to check my signals.
I know the encoders are substandard as far as resolution but just need to start my setup before purchasing higher resolution encoders.
I also get a machine set up not complete. thanks

Re: encoder differential error
Do those encoders have differential channels?
We could probably tell, if you had a picture that showed the right side of the label with all of the wire color assignments.
Can you describe which wires you connected to which pins of the 9-pin D-sub connector?

Re: encoder differential error
yes, it is a quad encoder
a, b and marker
a, b and marker(not)
+5 and ground
I followed diagram for wiring the db9 connector

Re: encoder differential error
If it is wired correctly, then the only other possibility is that the high and low logic levels do not meet Centroid's standard of 3.0-5.0V for high and 0.0-0.5V for low. What are your logic levels?
Post a photo of the DE-9 connector wiring.

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Re: encoder differential error
I can not find an datasheet but may have figured it out.
They offered an option for open collector output ,which would need a pullup resistor on all the lines.
can anyone find a datasheet for a LBL-041-500.

Re: encoder differential error
Sumtak is now part of Heidenhain. You might try contacting their customer service for a datasheet.
