ServoWire® Digital Drives Digital Servodrives ORMEC -1- SERVOWIRE® DRIVES ServoWire® digital drives provide high performance servo operation utilizing digital networking technology based on IEEE-1394 (FireWireTM). This network not only provides high speed, but also ease of use through costeffective, industry-standard cabling. Each ServoWire® drive supports a wide variety of high performance, encoderbased servomotors. Consult ORMEC for OEM applications of user-supplied brushless rotary or linear motors---as well as DC brush-type and voice-coil motors. Eight drive models range from 600 to 15,000 watts, and offer continuous current output from 2.4 to 60 amps RMS/phase. 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 or 230 VAC input power, and provide both output short circuit and overvoltage protection. All-digital design eliminates the troublesome analog interface between controller and drive systems, replacing it with a modern high speed network based on the IEEE-1394 standard. Performance ServoWire® drives combine alldigital operation with DSP technology to produce fast update rates and current loop bandwidths up to 1200Hz. High bandwidth current loops teamed with high resolution motor feedback combine for quick and accurate torque, velocity and position control. 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 MotionDeskTM software. Motor types 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. ServoWire® Drives -- At A Glance Eight models: offering continuous output currents from 2.4 to 60 amps RMS/phase. All-digital design: eliminates all manual drive setup including pots and jumpers Small footprint: provides high power density and reduces space requirements. Sinusoidal commutation: improves low speed torque ripple and system efficiency. Trapezoidal commutation & DC operation: provide user flexibility. Integral shunt regulators: add protection (All models except SAC-SW203 & SW205). UL/CE approvals: UL Listed and CE Mark (low voltage directive & EMC). Status Indicators: Large two-digit display for showing network ID and drive status plus six LED indicators which show condition of sensors, travel limits and motor over-temperature. ServoWire® Network Interface: Two connectors provide an all-digital control link to ServoWire® Drive Network. Network interface is galvanically isolated from the drive and powered by the ServoWire® Axis Module. Drive Power Inputs: Universal voltage input power accepts 115 or 230 VAC nominal featuring separate logic and bus power supplies with overvoltage protection. Flexible Drive I/O: ServoWire® drives provide three high speed sensor inputs, up to six optically isolated programmable limit switch (PLS) outputs- -(one of the PLSs can be used as a userconfigurable fail-safe brake control output), two overtravel limit switch inputs, plus two high quality analog outputs for monitoring motor velocity and torque. Convenient screw terminal pluggable connectors. External Regen & Bus Connections: Allows bus power to be shared between drives and/ or the addition of an external resistor for dissipating regenerative energy from the system (All models except SAC-SW203 & SW205). Brushless Motor Feedback Interface: Versatile encoder feedback interface accommodates differential or single-ended hall tracks, quadrature feedback, and optionally support the multi-revolution, absolute encoders available on ORMEC’s D-Series motors. Auxiliary Encoder Input Option: Provides an additional connector for a pacer encoder when applications require addition positioning information for web control applications. Also to be used for distributed feedback applications. Configurations for each drive containing the motor parameters, all operational limits for torque and speeds, I/O configurations, load inertia and servo loop tuning parameters are stored in the ORION® controller as part of a system project and automatically downloaded at power up over the ServoWire® network. Simple cabling accommodates up to eight drives per network, and provide for quick and reliable installation.
