Smart standard drives provide servo performance and precision

28 November 2015

Nord Drivesystems’ advanced frequency inverters and high efficiency geared motors can be combined to provide servo-level performance at very competitive costs when compared with traditional servo systems.

Nord offers a range of cabinet, wall mounted and motor-mounted frequency inverters with optional Posicon position control for use with its IE2/IE3 asynchronous geared motors or permanent-magnet IE4 synchronous geared motors.

Available with absolute or incremental encoder feedback, and with IEC 61131 programming support, Posicon supports medium precision applications where multi-axis coordination, flying shear, master/slave synchronisation or positon/product registration is required.

Nord’s SK 540E is the top-of-the-range control cabinet frequency inverter and integrates a universal encoder interface for SSI, BISS, EnDat profile 2.1, and Hiperface. In addition to absolute or point-to-point positioning functions the inverter offers incremental positioning and features such as teach-in, reference point, offset and target position, while S-ramps are easily programmed for complete application flexibility.

With output power for distributed inverter technology available up to 22kW and cabinet devices up to 160kW, other drive features available include a 200 percent overload capability and STO/SS1 for high safety applications whilst a wide choice of fieldbus extension modules including Profibus, CANopen, EtherCAT and EtherNet IP provides numerous communication integration opportunity.
