ServoWire® SD Servodrives ServoWire® SD Servodrives ServoWire SD 230 Series • Network Drives: Eight models offer continuous output currents from 2.5 to 60 amps RMS/phase • 600 to 15,000 watts of output power • 115 or 230 VAC input See page 22 for specifications ServoWire SD 460 Series • Network Drives: Six 460 Volt models offering continuous output currents from 5 to 50 amps RMS/phase • 2,400 to 24,000 watts of output power • 230 or 460 VAC input bus; 115 or 230 VAC for logic power See page 24 for specifications ServoWire SDdrives are designed to offer high performance motion control using all-digital servodrives connected via an open standard FireWire network. Two series of drives offer solutions with power from 600 to 24,000 watts, and continuous current output from 2.5 to 60 amps RMS/phase. ServoWire SD Drives ServoWire SD drives provide high performance servo operation utilizing digital networking technology based on IEEE-1394b (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 servomotors. Consult ORMEC for OEM applications of user-supplied brushless rotary or linear motors—as well as DC brushtype 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 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-1394b standard. Performance ServoWire SD drives combine alldigital operation with DSP technology to produce fast update rates, and correspondingly high performance. The high bandwidth control loops in the ServoWire SD Drives, along with highresolution motor feedback, combine for quick and accurate torque, velocity and position control. Position, velocity and torque loops are all closed in the ServoWire SD drives. This distributed control architecture allows for high performance without placing a heavy computing burden on the SMLC. Programmable Drive Configuration ServoWire drives have no pots, jumpers or field component changes whatsoever. Even factory adjustments are digital, automatically calibrated and stored in Flash memory. All user configurations are done in software using axis configuration tools in our ServoWire Pro software. Motor types ORMEC -20- SERVOWIRE SD SERVODRIVES Model 425 Shown are selected from a database of ORMEC standard products or the custom motor editor can be used to add other motor types to the database. Configuration data for each drive, containing motor parameters, all operational limits for torque and speed, I/O configurations, load inertia and servo loop tuning parameters, are stored in the SMLC and can be downloaded by the application program as needed over the ServoWire network. Simple cabling accommodates up to sixteen drives per network, and provides for quick and reliable installation. Standard Motor Interface ServoWire SD drives interface to motors that use encoders or resolvers. The encoders supported are quadrature encoders with hall track information, or serial encoders. The drives provide for smooth output torque by using threephase sinusoidal commutation. Field Oriented Control (FOC) and Space Vector Modulation (SVPWM) contribute to optimize performance at all motor speeds.
