General Mach Discussion / Re: motor tuning for vfd spindle

My Bridgeport mill just has manual speed control, was going to hook it up to Mach at some point but once I get the Beaver Mill finished I will probably sell the Bridgeport so I am not going to bother at this time.
On the lathe the speed is controlled via clutches in the gearbox and Mach switches between the clutches over ModBUS so really maybe these are not good examples for you in as much as the actual speed control, however both read exactly what they are supposed to and if anything the reading fluctuates by 1 RPM. I dont have spindle speed averaging checked so I know that is a true reading.
