Zero-Speed Controls

A simple, sensorless solution to increase machine safety

Machinery applications involving high-inertia motor-driven rollers or spindles present unique challenges for machine safety engineers who are tasked with minimizing the risks to machine operators and maintenance technicians. Although operator safety "best practices" are a part of any machine safety program, they must be coupled with robust mechanical means of detecting motor rotation, preventing access to dangerous areas, and otherwise ensuring operator safety.
