Allen‑Bradley 20G11N VFD

Feature & Principle

It is Rockwell PowerFlex 755 high‑performance AC drive. It converts fixed AC input to adjustable frequency and voltage output to realize closed‑loop speed and torque control. Built‑in EtherNet/IP for high‑speed network connection with PLC. It supports dual ND/HD rating, dynamic braking transistor, rich safety and protection functions. Modular design allows option card expansion for encoder feedback and safety control. Widely used for heavy‑duty industrial motor control.
