Mitsubishi Electric FR-F720-11K Variable Frequency Drive

The Mitsubishi Electric FR-F720-11K is an 11 kW, three‑phase variable frequency drive that precisely controls speed and torque for industrial AC motors, with common applications on conveyors, pumps, fans, and machine tools. It accepts 380–480 VAC three‑phase input and outputs a motor‑matched variable voltage, delivering roughly 22–25 A (drive class dependent) and using V/f control with sensorless vector options to cover a typical 0–400 Hz range. Cooling is via a built‑in fan/heatsink, it mounts in panels or cabinets, and it includes protective features such as overcurrent, overvoltage, overload, and short‑circuit protection, plus optional fieldbus communications (MODBUS/CC‑LINK/DeviceNet) and status/fault LEDs with a keypad display. For upgrades or replacements, Mitsubishi FR-F740-11K is listed as a common replacement offering enhanced performance, while the FR-F720-11K remains a standard choice in manufacturing and building automation environments to improve process control, energy efficiency, and reduce mechanical stress across conveyors, HVAC systems, material handling equipment, mixers, extruders, and production machinery.
