I was just looking at that. I seem to have a problem that I can't find a solution to. Basically the IRAMS module is ignoring me. I can scope the H(1,2,3) and L(1,2,3) pins and see a nice 0-5v square wave on one H pin, the same on a different L pin and all the other pins held high. However the power stage seems to ignore that. It will sit there with the motor not moving. if I touch wires to the motor terminals in the requested configuration then the motor turns, and in the right direction, so I am confident the control signals are right, if only the IRAMS would do as it is told. -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
