I could put the Resolver to Hall signal code up on the Wiki, but I a lot less confident that it is "right". Specifically I am not sure which of the zeros of the resolver is considered zero degrees and how the Hall signals typically correspond to that angle. It also needs adjusting for different numbers of motor poles. If you are happy to fiddle with the table that correlates Hall signals to resolver angle then I can publish the Arduino code somewhere. It is something that seems fairly risk-free to tinker with, as the worst-case is that the motor just stalls and vibrates. -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
