I have a fanuc M-430iA with a Fanuc R-30iA controller.
While setting up a new line for visual tracking I was testing the pulse coder that is attached to the conveyor:
xgfg5z
I think this is an incremental  encoder, but I'm not sure.
2mcgksh
So these are my settings:
5u1uon
Now my thought was that when I press Encoder Enable and move the conveyor, the Current Count should change.
But that's not the case, it stays 0.
Does that mean that the pulse coder is broken?

Have you already tried all the other "Encoder Types" just to make sure that's not where the problem is?

Remove the encoder from the conveyor and turn the shaft by hand in both directions to see if the value changes.

Yes, I've tried Them all (with cold starts) but it remains zero.

I doubt that it would change anything because the Shaft is rotating, but I Will give it a try

EDIT: one 'absolute' changes from like 7427631 to 7427632 to 7427630 etc. but it does the same thing when it's disconnected

I've edited your posts so they are not nested quotes within quotes with responses in order in increase readability.

Is your FSSB interconnect cable from the line tracking card to the CPU missing? I had that happen once, and it produced similar symptoms.

Check out the position converter I wrote here!

My bad for the quotes, but that might actually be the case.
This is how it looks right now (The pulse coder is connected to the JF21 port):
2ii7j13
Is it correct that the cable that is now in the left cabinet (C0P10B) should go to the C0P10A of the line tracking cabinet?
And that the short cable that is now going nowhere should go from the C0P10A of the left cabinet to the C0P10B of the line tracking cabinet?
It would be great if this is the problem, thanks!

Yep you are correct. The six axis amp gets placed into the line tracking card, and the jumper goes from the card to where the amp used to be.

Here is what the manual says about it:
Fiber Optic FSSB Connector
When a line tracking interface board. A2OB-8101-0421 (Wide mini slot) is used The original fiberoptic FSSB cable connector that connects to the COP10A connector of the main CPU board should be moved to COP10A of the line tracking interface board. The additional fiber optic FSSB cable should connect COP10A of the main CPU board to COP10B of the line tracking interface board.
