Which is one of the reasons I'm still putzing with register settings. I'm running it, but only fwd at an LCNC set speed ATM. rev is being ignored. Looking at the block diagram on page 12, there is no voltage on the fwd-rev terminal when the spindle is off. There was with the old 110 volt vfd, opens at the 7i76 had +10 volts on them and sensed the ground to enable fwd or rev. So I'm still reading thru the exceedingly fine print for a clue as to why there is not a voltage there so the ground from the 7i76D can be sensed. Either a wrong setting someplace, or I have a defective vfd. Needs additional investigation but its 2 to 3 steps up a stepladder and my back's crushed discs limits the time I can stand and balance there to 2 or so minutes at a time. But that's my problem, not yours ;-) When I do find it, I'll mark it down in the back of the booklet. Thanks Andy.
