The author details hardware specifications related to the operation of machine service drives and outlines troubleshooting methods for problems concerning machine nonlinearities, inertia, drive stiffness, and friction. He highlights recently developed simulation methods used to predict, assess, and improve the performance of service systems and their components and covers the function and assembly of drive systems, drive resolutions and drive ratios, and duty cycles."--Publisher description ER -
