**RESOLVED** SPINDLE SPEED options with CENTROID SOftware.
Posted: Thu Mar 17, 2011 2:02 am
I am leaning towards purchasing the CENTROID software as opposed to using MACH3 on my mill conversion. I am ok with MACH and use it on other tools but the more I play with the CENTROID DEMO the more I like the feel of it.
The big question for me is what is possible as far as having actual spindle speed shown and maintained within the software? My spindle is currently a 3phase /3hp motor running on 1phase 220V with a MITSUBISHI VFD. It does have a mechanical 2 speed gearbox for hi and low range (currently no switches to use as inputs to plc) . reduction is approx 6.3:1 The spindle doesn't currently have any sort of speed sensor so I am free to add what is required. Also I guess the question is do I need it at all? Can the software merely check the output frequency of the drive and interpolate the speed from that assuming the loads are relatively light and not slowing the rotation?
I wonder what others have done on their conversions
