Hi,

I'm tempting fate here a little bit. We shipped the 1,000th G203V REV4
today and I have yet to hear of anyone blowing one up.

The G203V is a 7A/phase, 80VDC rated microstep drive meant to run big motors. Big motors beat little drives up unless the little drives are used very carefully but not everyone does. The ace up the G203V's sleeve is it has every protection circuit from here to Sunday making it a little harder to beat it up.

All orders have been for 20 units and less; statistically there should
have been between 40 to 80 drive problems in this units per order size
catagory were they G201s.

I have had only one G203V REV4 support feedback where someone applied
72VDC reveresed power supply polarity and promptly blew the internal fuse.
He tracked down the fuse part number, replaced it and the drive ran
just fine afterwards.

That's it for all G203V REV4 support requests/feedback to date. Just
that single one. Is anyone actually using them? This is kind of eerie
for a new design.
