FR-E700: The new FR-E700 series, in addition to better features and performance than their predecessors, the models in the new series are also more compact and even easier to install. Improvements include an integrated USB port, an integrated one-touch Digital Dial control with a display, improved power usage at low speeds and an expansion slot compatible with the many option cards from the 700 series. All this makes the FR-E700 an economical and highly-versatile solution for a wide range of applications from textiles machines to door and gate drive systems to material handling systems.
