The Mitsubishi Electric FR-AF840-05470-60 is a high-performance, three-phase 400V inverter belonging to the renowned FR-A700 series. With a rated capacity of 3.7 kW, this inverter is engineered to meet the demanding requirements of advanced industrial applications, offering exceptional drive performance and operational flexibility.

The FR-A700 series, to which this model belongs, is widely recognized for its suitability in high-load applications such as crane systems, elevators, printing and packaging machinery, textile and dyeing equipment, material winding processes, and various other general-purpose industrial uses. It provides a superior level of drive performance, ensuring stable and efficient operation even under challenging conditions.

A standout feature is its proprietary sensorless vector control mode, which enables precise and powerful operation at low speeds without the need for an encoder. This makes it ideal for machinery requiring smooth rotation and high torque from standstill, while reducing system complexity and cost.

The inverter also includes a dedicated torque control mode, allowing for direct regulation of motor torque. In speed control mode, a torque limiting function can be activated to protect mechanical systems and loads from excessive force, enhancing both safety and equipment longevity.

Furthermore, when combined with an encoder, the FR-AF840-05470-60 supports full vector control. This configuration enables advanced capabilities such as accurate position control, high-speed, high-response speed regulation, zero-speed control, and servo lock functionality—making it suitable for sophisticated automation tasks that demand precise motion control and dynamic torque responses.
