ELECTROMAGNETIC COMPATIBILITY OF ROBOT CELLS FOR INDUSTRIAL APPLICATIONS

摘要

The failure-free operation of modern robot cells is guaranteed only if the electromagnetic compatibility (EMC) of all devices and the overall system is ensured. So EMC is one of the finest premises to high reliability of robot cells. However, today's EMC directives only refer to individual components and devices. The system as a whole is meant to comply with the EMC protection requirements if all of its parts meet the EMC directives and are assembled according to the manufacturers instructions. But normally properties intra complete robot cells are still unknown, because robot cells arc structured individual as special machines. For this reason and due to the fact that setting up facilities to resolve EMC problems in a plant is very expensive, EMC of complete robot cells will be researched. The following problems are explored in the paper: How can interconnection and arrangement of certified individual components affect EMC characteristics of the robot cell? What methods are required to conclude EMC values of the whole cell from EMC values of individual components? Are EMC guidelines for individual devices sufficient, or are additional EMC guidelines for cells and facilities necessary? Solving these problems, it is possible to raise reliability of robot cells.
