Re: 2 Fried G210's in a single day :-(

Followup:
Well, I just got off the phone with Mariss and I won't even go into
how much I did wrong, but suffice it to say that a couple things
were indeed wrong with my setup.
If you think Mariss knows alot from his posts on the board, then
don't call him unless you've taken your Ginko Galoba because you
will be saturated with information very quickly.
He was extremely helpful and hopefully the problems are resolved.
My only wish is that the manuals were a bit more explicit in what is
a "tune up" sort of thing and what is a "blow up" kind of thing.
For instance, I did not put the capacitor in the power line since
my leads are more than 18" from the power supply (didn't have any
handy), but I wrongly figured this was to somehow smooth out the
voltage but might only loose a bit of performace without
them...wrong... they are critical to the safety of the drive.
Another thing I learned from Mariss is that fuses between the DC
supply and the drive act as resistors and increase the need for this
cap.
To go on...
I also learned that when you use only 4 wires of a 6 wire motor,
that you are in essence changing it from a parallel configuration to
a series and need to limit the current. My understanding was that
the motor was rated at 8 amps from the factory, and that it was
series wired from the factory, meaning that it would require 8 amps
in the state it was in unless I *changed* the wiring so I didn't
have any current resistor in there....mistake. Not connecting those
two extra wires put my current needs at 4 amps.

There's a bit more, but I'll refrain.
I just wish the manual contained some warnings directed at us who
know little about motors and motor windings. It's pretty much all
there in the manuals, but I didn't get the significance of certain
parts over others.

The bright side is that Mariss doesn't abandon his customers and is
willing to try to come off of planet electron for a few minutes to
explain in layman's terms how to do it the right way....which in my
case is close to an hour of explaining.
Geckodrive just needs to add a few more "Drive's for Dummies"
sections to their manual but their customer support is beyond
compare and if I were in the position to rate it, it would receive
the highest possible that I could give.
