One my 10T controller understands some interpolations and another - no. It even has less options in IPL mode.
That, wich can interpolate is with red caps motors, wich can't - yellow caps motors. Numbers of motherboards I don't remember now. I can impart later.
What do you think, is it possible to swap EPROM software from red caps fanuc with yellow caps fanuc? Or find, in one's way, upgrade EPROM soft for "emasculated" controller?
