altYET US (Manchester, NH) introduced the XtraDrive® servo system, configured for compatibility with all brushless servo motor technologies. The unit features patented non-linear control technology (NCT) for performance and stability; NCT technology allows for zero settling time, and augments non-linear gain control and system productivity. The control structure accommodates changing load requirements, and features an integrated amplifier with an embedded 1.5 axis controller. The system operates as a standalone unit or can be driven by an external PLC or multi-axis controller for step and directional input, analog velocity, or torque control and networking capability. Options include extended I/O, Devicenet, SERCOS, MACRO, and Profibus.
