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).

Rockwell's PowerFlex 700 to PowerFlex 750-Series migration guide carries a parameter cross-reference; parameters are re-entered or mapped, not copied, because the 750-Series parameter numbering differs.
The HIM and communication adapters change: 20-HIM-A3/A5 give way to 20-HIM-A6/C6, and 20-COMM-x adapters to 20-750-xxx option modules (the 755 has EtherNet/IP embedded).
Frame sizes and mounting differ between a PowerFlex 700 and the equivalent 753/755, so check the panel layout and the 750-TD001 dimensions before ordering.

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.
