Now fill your optical encoder with coolant and see how it goes. I may be sounding like a bit of a resolver fanboi, but that is because I am. I have even taken off an encoder to fit a resolver on one of my lathe servos. With a resolver that perfectly matches the motor it makes BLDC commutation very easy too. On the Z servo of my lathe absolutely all that is needed is: net z-angle hm2_5i24.0.resover.01.angle => hm2_5i24.0.8i20.0.1.angle net z-pid pid.1.out => hm2_5i25.0.8i20.0.1.current -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
