Hi Doug. Are the resolvers right on the motors and is there also a tach in the end? Your motors are probably newer than the DC ones I've got here. I opened these up the other day and removed the tach at the back. The shaft is 12mm so I'm cutting a little adaptor plate to match up where the magnet poles screwed in and putting USDigital E3 encoders inside where the tach was. That will allow me to use the existing sealed motor covers. Since the cable will plug right through the peckerhead (motor junction box), I can still wire in flex. That mod means I can't use the Kollmorgen drives because they required the tach.
