Update, I found some old photos of the motor’s id plate. I thought it was rated at 6000 rpm at 110 volts, but it was really only 3000rpm at 110volts. When I adjusted the maximum rpm in PNCConf, suddenly I was getting a solid “At Speed” indicator.
John, I will still try measuring the analog voltage at various rpms and if I can get at it I will measure the DC voltage out. Peter, Thanks for the suggestion about the encoder phasing, I don’t think it was going to work without fixing that. Gene, Could you go ahead and send me your configs. I can have a jackshaft driven by toothed belt with a 3 step pulley or a pair of three step pulleys on the motor and spindle. So six possible gearing combinations. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
