  8. Engineered Precision Motion Design Benefits From Systems Approach 8/23/2017

    When controlling motion at the sub-micrometer or nanometer levels for alignment and handling applications, it is imperative to have high reliability, robustness, minimized latency, and high-speed synchronization with external devices to reach sub-micrometer path accuracy. The higher the dynamics and throughput targets of a multi-axis precision motion system, the more holistic the design approach must be in order to achieve success. A systems approach where the mechanics, control electronics, and software are designed by the same team provides a great amount of benefits for the user.
