Indramat's DKR05 Intelligent ac Vector Drive provides the dynamic performance of a servo drive while reportedly delivering 30 times the torque. It meets the high performance needs of newspaper printing presses, converting machines, high-power machine tools, and high-horsepower engine and transmission test stands. The drive comes in models offering 150, 200, and 300 hp, at motor speeds to 2,700 rpm, and connects directly to 380/460V ac power lines, with regeneration back to the three-phase powerline. DKR05 uses the fiber-optic digital SERCOS interface to provide high-speed, noise-immune, real time between the control and digital drive, which further reduces wiring.
