I would suggest that that would be a downgrade. Buying resolvers new would be needlessly extravagant, they cost a fortune, but if you already have them then they are superior to encoders. In this case the existing drives probably use the resolvers for commutation too. (which might be a problem, as the Mesa Resolver card expects to be providing the excitation. However the drive quite possibly won't notice if the excitation is swapped to the LinuxCNC interface hardware.). Pete: Do you know if the drives use Hall sensors for commutation, use the resolvers for commutation, and pass-through the sine/cosine, or use the resolver and pass out synthetic encoder pulses? -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
