Accuracy Investigations of Multifunctional Two-coordinate Drive

Abstract

In this article there is analyzed one of the most important characteristics of two-coordinate drive systems, i.e. position absolute and repetition accuracy. The influence of control methods, that ensure optimum rapidity and increase durability of the system and power efficiency, on position repetition accuracy is evaluated. The experimental measurements were carried out using industrial drives. From experimental results and statistical evaluations it can be concluded that position absolute and repetition accuracy of two-coordinate drive system do not come worse using control methods, that ensure optimum rapidity and optimization of mechanical actions to the mechanical part of device and optimization of power consumption.
