Hello,

Your query is not clear.

Do you want to vary spindle speed during cutting?

or 

Is your machine spindle speed varying/changing automatically during cutting?

Please specify type of machine & other relevant data like type of spindle drive article number, type of spindle motor, motor nameplate, is motor encoder for spindle speed feedback or external encoder mounted to spindle etc. etc. 

 Do not quit understand what you mean! guess--see attached file for 802D NC programming

Hello,

Is there a way to implement Spindle Speed Variation (Spindle speed constantly goes up and down during a cut) on the 802D?

I found a document for the 828D but this does not work on the 802D.

Is there a cycle or some other way to do this on the 802D?

Thanks.
