Intended Use | Intended for high-performance vector drive applications. PowerFlex 700 drives handle extruders, winders, cranes and hoists, centrifuges and large conveyors with flux vector control and encoder feedback. | ||
Migration Path | Rockwell Automation has discontinued the PowerFlex 700. Published successor for the PowerFlex 700: PowerFlex 753 (20F) or PowerFlex 755 (20G).
A like-for-like replacement or a repair keeps the existing program, wiring and panel layout; a migration is a project. Both are listed on this page so the choice can be made on lead time and budget. | ||
