If swapping the A & /A with the B & /B pairs does not reverse the encoder direction, its possible you have some other problem like differential pairs mis-connected, say: ENC A 7I33 A ENC /A 7I33 B ENC B 7I33 /A ENC /B 7I33 /B Or maybe some general electrical problem... Its also possible that theres a problem with the 5I23 configuration (which one are you using?) but thats fairly unlikely. I can test it with a 7I33 on Monday. > > I'm using the Mesa 5i23 along with the 7i33 and 7i37 card. > > Donnie > > Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
