Looking for a DC Servo Drive recommendation (affordable $) to drive my 3-axis plasma table...The controller is Galil DMC-2183, motors are Baldor MK-2250-BLBCN. My Baldor TSD servo drives keep throwing over current limits and I constantly have to power them on/off or reset....they are old and my POTs adjustments are highly over sensitive....Can anyone recommend a good affordable replacement?

thanks,
Brian
