hi Uwe,

understand, so i have a 2000 Line Encoder on the spindle, more is not supported because of high rev ?

a 9000 line encoder would be an issue for closed loop C-Axis because much slower. understand.

but why is it not possible to use the 2000 Line Encoder for the C-Axis ? of course, less ...

Hi Uwe, are you serious?

Why do i need a second encoder, which does exactly the same than the first one? I didn't know that. Encoder on servo does not help me, i want to correct the V-Belt errors with it.

Is there a possibility for a Software solution or are there splitters for the encoders ...

but an additional question - where is the encoder feedback here ? the encoder should realising, that the rotation of the control and the rotation of spindle are not fitting together and give an error message or correct the position / speed, etc.

and the spindle servo isn´t very rigid right now ...

hi

now i found a complete manual with around 150 pages - but no new information regarding the pulses. the solution was quite easy. i tried 0,625 in the "deg/rev" box and this works quite well. no idea, why i didn´t tried it yesterday.

controlling the axis is also fine, first test programm was ...

hi Uwe,

thanks. The Servo is switching to Position Mode when activating M51. i see the centroid output activ and the servo become rigid. so this seems to be successful.

this is the manual i have from the servo, no parameter to configure puls per rev or something like that:

hi guys,

since my lathe is running now very good and stable i want to go the next step and implement the C-Axis with Live Tooling.

i use a 3,7KW Spindle Servo, which supports switching from speed to position mode

i wired it like this:

In Fact it was an issue in my offline Intercon. When i sent it to my machine, It worked well.
Thanks everyone.

But it was turned without radius compensation. Works in my case, but would be great, if this could be implemented in a Future Release.

Thanks

Michael

It is hard to guess without seeing a copy of your Intercon program, but my guess is that you used a Profile cycle, and entered a non-zero "stock to leave" value on the Z axis.

With such steep walls on both left and right, you will want to leave the Z axis "stock to leave" amount at zero. Just use ...

hi guys, i have a question.

i want to turn a Poly-V Pulley on my lathe. so i did a 3D Model in CAD first

and afterwars i did the programming in intercon:

as you can see, i have some crossing from the roughing path and the ...

hi, yesterday an similar issue, but this time more critical, because it was not visible before in the graph.

i made a very simple inner profile with 17,5mm inner diameter, file looks good in the graph. the tooling itself was good, tool was at 17.5, but the way back it goes at 17.8 in diameter and i ...
