In principle, sending a pulse-stream as a velocity command is not so different from sending an analogue voltage. Do you know what communication methods are available at the drive end? > I need to determine what kind of BOB to install in the machine that > both allows them test the machine before shipment and me to easily hook > it up to my computer when it arrives. I would be tempted to ask them to check with their normal interface, then not ship it. But I don't know much about the system. > Also which type on encoder should I ask for. Incremental or Absolute. Incremental is likely to be easier just because it has been done so many times. Do you know what the data format of the absolute encoders is? I personally like absolute encoders, but then I also like a challenge :-). Mesa have an interface for SSI and BiSS encoders, but I don't know of anyone who has actually used them on a machine yet. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
