Re: Step/direction servo amps

http://www.granitedevices.fi has the best value in servo drives BY
FAR. They are 100% digital and can be tuned right from your PC.
There is no guessing involved when it comes to how much
overshoot/following error your machine will have. However, these
drives are rated at 15A peak, which is a little below what you want.
However, I think 20A for a servo drive is very high. If you need more
speed, it's the voltage you should worry about. How big a machine are
you talking about where you would need such high power/current levels?
