Mitsubishi Electric FR-A720-22K Variable Frequency Drive

The Mitsubishi Electric FR-A720-22K variable frequency drive precisely controls speed and torque for three-phase AC motors in industrial automation systems. Used in conveyors, pumps, fans, mixers, and machine tools to deliver smooth speed variation, soft starting, and energy-efficient motor control, it supports motor control upgrades and process optimization for maintenance teams and system integrators. Key specifications: Model FR-A720-22K; drive type: variable frequency AC motor drive; rated output power: 22 kW (≈30 HP); input voltage: 380–480 VAC, three-phase; output current: approximately 40–45 A depending on drive class; control methods: V/f control and sensorless vector control; frequency range: 0–400 Hz; protective features: overcurrent, overvoltage, undervoltage, overload, and short-circuit protection; cooling: built-in fan or heatsink; mounting: panel/cabinet mount; communication: optional fieldbus support (MODBUS, CC‑LINK, DeviceNet); indicators: status and fault LEDs, keypad/display; designed for: industrial motor speed and torque control; operating temperature: industrial environment range. Common applications include conveyor lines, HVAC systems, material handling equipment, extruders, printing presses, and packaging machinery where variable speed operation improves process performance and reduces wear. Common replacements: Mitsubishi FR-F720-22K, Yaskawa GA500-22KW, ABB ACS580-22K.
