Grounding and Shielding is an often misunderstood process. It is common to hear quotes ranging from “it’s just black art!” to “the rules change all the time!” and “there’s no way to understand it!” These emotional statements are repeated but not true. There is a process, it hasn’t changed, and the more one knows about coupling mechanisms the more one will see that it’s sound engineering principals.

The need for Ethernet-based communication within the factory has grown over the last 10 years. Detailed information about the tasks and performance of machines at every stage is critical to productivity. As capabilities have expanded from performance reporting to predictive maintenance warnings and beyond, the need to connect multiple controllers within the same machine and elsewhere in the factory has also grown.

Sizing and selecting a servo motor system for a machine design begins by understanding the components that make a servo motor or servo-drive system. Servo systems are closed-loop, controlling some desired motion. They incorporate a feedback device that provides constant information between the motor and drive to precisely control position, speed and torque to the mechanism being driven.
