Hmm - that looks like the Quick Turn 20 universal we just got. Has the T2 control (1985). We are in the process of starting the conversion. I had just assumed they where 'normal' resolvers.but had decided to swap them out for encoders. We plan on using some AMC drives for the axis and try to keep the VFD until it fails. (looks like at least one of the original axis drives had been tampered with as they had been chasing a problem with the x axis - new ball screw, new resolver...)
