Introduction

In modern manufacturing facilities, motor drives for industrial stationary and mobile robots can help increase factory output, efficiency and safety. But as employees in factories work alongside increasingly numerous (and increasingly powerful) automated robots, system designers must meet more strict safety requirements. Powering on and using standard or emerging technologies must be safe under any and all circumstances to enable true collaboration between employees and robots. Additionally, appropriately powering off or making operating adjustments in the event of a failure is a primary element of safety. The safe power design for these robots or other electronics is essential to achieve system-level functional safety requirements.
