Product Description

Description

Engineered to deliver exceptional motor control performance, the Mitsubishi Electric FR-A840-2.2K-1 is a highly reliable variable frequency drive (VFD) from the premium FR-A800 series. Designed for demanding three-phase industrial operations, this inverter provides precise speed and torque regulation for standard AC induction motors as well as permanent magnet motors. With a rated output capacity of 2.2 kW, it offers robust energy-saving capabilities, advanced vector control technology, and extensive network compatibility to ensure seamless integration into modern automation architectures.

The unit features versatile built-in communications, supporting RS-232, RS-422, and RS-485 protocols for direct connection to PLCs, HMIs, and supervisory control systems. Its industrial-grade construction is optimized for reliable heat dissipation and long-term durability in challenging environment conditions, making it an excellent choice for complex machine control and infrastructure applications.

Features

  • Advanced motor control algorithm compatible with both induction and PM motors.
  • Integrated multi-protocol communication interfaces (RS-232/422/485) as standard.
  • High overload capacity suitable for heavy-duty industrial start-up cycles.
  • Compact physical footprint designed for efficient cabinet space utilization.
  • Strict adherence to international safety and quality standards.

Applications

  • Conveyor systems and material handling machinery.
  • Industrial fans, centrifugal pumps, and blowers.
  • Extruders, mixers, and winding machines.
  • Compressor control in HVAC and refrigeration plants.
  • Machine tool spindles and positioning axes.

Installation Guidelines

  • Mounting: Mount the inverter vertically on a flat, non-combustible surface to facilitate natural convective cooling.
  • Clearance: Maintain a minimum clearance of 50 mm above and below the drive, and 10 mm on both sides to prevent thermal buildup.
  • Grounding: Always connect the protective earth (PE) terminal to a dedicated ground point to prevent electrical shock and reduce noise.
  • Wiring: Isolate control signal wires from high-voltage power cables. Use shielded twisted-pair cabling for all RS-485/422/232 communications.

Compliance and Certifications

  • CE (European Conformity)
  • UL Listed
  • cUL Listed
  • RoHS Compliant (Category 6)
