That looks like an attractive turnkey solution, but it also makes the Mesa 8i20 2.2kW brushless drive look like a bargain. The Keling KL34BLS-98 is $134, and about equivalent to that 400W Teco motor and a (very overkill for that motor) 8i20 is $239. The cabling costs need to be considered too, of course, and encoders. Having checked, the $150 Pico brushless motor amp is possibly a better fit for that sort of motor size. I like the 8i20 with EMC2. It's a properly dumb drive, where EMC2 says "give me this current at that electrical angle" and it just does it, allowing you to move all the control into EMC2. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Get a FREE DOWNLOAD! and learn more about uberSVN rich system, user administration capabilities and model configuration.
