This is probably a question to lathe users.
Hello. I am finishing a lathe where I do not have spindle feedback, by my option. The spindle works fine at the desired speed, it is not so important.
I know the speed of the spindle based on the frequency that the inverter is outputing to the AC motor. Until this no problem. I probably have +-100 rpm but that is ok for my work.
The problem is that I need CSS. For what I have read, it is necessat to have the spindle feedback.
If I consider that the real speed is equal to the spindle speed set up by mach, CSS should work.
There is any way arround this one ?
Thank you

Looks like the CSS function would just monitor OEM DRO 202 instead of 39 but I wouldn't know where or how to change it.
Would be a neat option though.

In fact there is an option in the ports&pins -> spindle setup -> special funtions
that have: Use spindle feedback in sync modes
If it is unchecked, it should do exacly what I want, but it does not work, still expects the feedback.
Probably this is not implemented ?
Anyone ?

OK, dumb question: What is CSS??
