Re: Servo drives- Mariss Rutex PID and Tuning with a O-Scope

Tuned or mistuned, a servo will arrive at the correct place. All
tuning does is optimize the settling time. This for most applications
is of little consequence.

Rutex is a competitor to our drives but I can say nothing bad about
them because they have always been a fair and honest competitor. Like
us, they build good drives at a good price.

There are people that prefer them just as there are people that
prefer our drives to theirs. It's a Coke versus a Pepsi kind of
thing. I'd rather not be goaded into putting a fair and good
competitor into a bad light. The world is big enough for the likes of
us and them and a dozen more.
