Abstract

A servo driven mechatronic system simulator and analyzer utilizing preconfigured motion equipment profile databases to predict the behavior of a motion system based on a user selected configuration. The user can adjust the parameters and rerun the simulation and analysis many times in an efficient manner until the optimum operating conditions of the desired system are reached. The user can then archive the system design and implement the system with a greater level of confidence in the ability of the design to meet the requirements of the application.
