Hello, all, I've been thinking about how to best deal with CNC control of spindle speed on a machine with manually-changed belts and gears. I think I can rig optical sensors for the belt that would report what belt ratio is set. Detecting the position of the backgear handle is easy. So, the question is what to do when the belt/gear ratio is inappropriate for the requested Sxxxx speed? The most optimum would be a message pops up saying "Backgear is engaged, can't reach 2720 RPM, press R to resume when problem is corrected." That is most likely not easy to do with the current EMC2 setup. Probably the worst workaround would be to set the VFD for the maximum safe speed and muddle through, and hope the operator notices it doesn't "sound right". So, anybody have any ideas on how best to handle having EMC deal with the case where the belt/gear is put in the wrong selection for the requested speed?
