Inmoco has extended its networked servo drive line from ORMEC, with the introduction of the SD Drive family. Consisting of 14 drives, ranging in size from 3 amps to 60 amps, the ServoWire SD range provides high performance servo operation utilizing high bandwidth digital networking technology based on IEEE 1394b. More robust, efficient and faster than the previous 1394a network, 1394b defines a roadmap to 3.2 G-bit signalling as well as definitions for additional communications media (e.g. fibre optics).
