I have put my Hall-sensor emulation code on the Wiki (as a link on the same page). It is happily running my servo upstairs at this moment. There is something odd that unless the speed is set just right it keeps stopping. If I check the Hall signals with it stopped there is a perfectly good Hall code, but there is +30V on all of the motor terminals. I think this is either a peculiar drive fault, or possibly the rather oversized motor for the drive (30V drive, 300V motor) might be latching-up one of the drivers with back-emf (Is this possible? It is purest speculation) http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ResolverToQuadratureConverter -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
