Spindle Encoder

The 7I85S encoder inputs are identical to the 7I96S encoder inputs
so I would not expect a different result.

If the encoder position does not change when the spindle moves
its most likely an electrical or wiring issue. Checking the voltage levels
at the encoder inputs as Andy mentioned is a good way to check.
Note the for differential encoder signals, you should measure from
A to /A and from B to /B. The voltage across the pins should be positive
in one case and negative in the other (it should never be close to 0V)

In addition to checking the voltage levels, you can check the hal input-a and input-b
encoder signals.

I'll try it out a bit tomorrow and I have everything wired as in the instructions. I can not imagine synonymous that the encoder is broken. I have also tested another one and otherwise my servo would not run because it regulates itself via the encoder

I would not expect the encoder or the 7I96S to be broken,
but rather a wiring error or something similar, which is why
it makes sense to check low level things like signal levels
first.

I will check it tomorrow, I will swap the cables between A+ and A- etc

maybe the encoder 00 is a different input than the one on the 7I96S.

Yes, if you have loaded 7i96s_7i85sd firmware, the on-board 7I96S encoder is encoder 4
(so the 7I85S encoders become 0,1,2,3 as expected)

haha, yes i loaded the firmware i think that's my mistake that the wrong input is. I assumed that the 7I96S is the motherboard and therefore always comes first. But if what you say is true, it's encoder 4 and therefore it can't work at all. Since encoder 00 is input in the hall, I put the encoder on the 7I96S, which according to your statement is encoder input 4.

Hello,

I was able to do some tests today, I have A and B signals now, but I still have no index signal. I tried today to generate this with an npn sensor and an encoder but I could not generate the signal. I also tried it on the 7I85S, the index signal is also missing here.

I also have the problem that when I use a Fusion program, the machine stops at G43.

Do you have the index input set for TTL mode?

(this is necessary for single ended or NPN inputs)

Note that index is often difficult to detect by monitoring the index pin in hal
because it is typically a very narrow pulse.

The best way to check for index is to issue the halcmd:

sets spindle-index-enable true

and then check the state of spindle-index-enable as you manually rotate the spindle.

If working, spindle-index-enable should go true when set and false when index occurs

yes i have set the jumper to tll i will try to set it to true manually tomorrow.

Jumper is W3, which I have set from right to left, so the others W1 and W2 are still on the right because of the encoder.

but I still don't understand the G43 thing
