ServoWire SM Drives

ServoWire SM drives provide high performance servo operation utilizing digital networking technology based on IEEE-1394 (FireWire). This network not only provides high speed, but also ease of use through cost-effective, industry-standard cabling. Each ServoWire drive supports a variety of high performance, encoder-based servomotors. Consult ORMEC for OEM applications of user-supplied brushless rotary or linear motors—as well as DC brush- type and voice-coil motors. All ServoWire drives utilize reliable IGBT-based intelligent power modules and provide a cost effective solution for today’s motion control applications.

ServoWire drives operate on DC, 115, 230 or 460 VAC input power, and provide both output short circuit and overvoltage protection. All-digital design eliminates the troublesome analog interface between PC and drive systems, replacing it with a modern high-speed network based on the IEEE-1394 standard.

Performance
ServoWire SM drives combine all-digital operation with DSP technology to produce fast update rates, and correspondingly high performance. The high bandwidth control loops in the ServoWire SM Drives, along with high resolution motor feedback, combine for quick and accurate torque, velocity and position control. Position, velocity and torque loops are all closed in the ServoWire SM drives. This distributed control architecture allows for high performance without placing a heavy computing burden on the SMLC or host PC.
