There are pins designated for that on the 7i76D, what seems to confuse folks is that the spindle speed is an electronic resistor that acts exectly like the arm of the front panel speed pot on the vfd, but the vfd must be programmed to use it that way. Print the 7i76 manual and reread it, it is explained. Less clearly done is the explanation in the vfd manual as most are chinglish or engrish translations that are only half-assedly done. Sometimes they switch halves in mid sentence too, just to make it interesting :-[ > regards > > Andrew > > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
