I took a brief look at the Rutex site and they claim a faster and
better PID for more stable control. Faster than what?? I think than
their old one ?

They show a screen shot of the stable motor operation. And, I gather
that screen is from the software monitoring the motor paramters ?

Also, the people who have po-poo'd G-320's seem to all complain about
tuning. (one was upset that he couldn't tune it without having to
spend the extra $$ for an encoder) but also, everyone who has used a
scope to tune them speaks highly of the drive.

Since there are a few pc-scope free-ware programs, I assumed that
people are using them to tune the servo drives, and that being the
case, I also assumed that someone would have done a "ho-to" about it.

I also assume that 90% of the people tune them quickly and easily or
at least satisfactorily, from the methods at hand.
