Q. How do safe motion systems work? What role does advance motion control technology play?

A. Reliability theory has been applied to adjustable speed drive technology to define the reliability required for safety applications. There is an acceptance in industry for concept of integrity levels. Higher CPU power, reliability of components and a high level of diagnostics to detect dangerous faults before a failure can prevent a safety function from occurring has allowed these functions to be realized. Application of redundancy and diversity to complex control systems provides a means to predictable and acceptable failure rates.
