Mitsubishi Electric FR-A840-00380-2-60 FR-A800 Frequency Inverter

Description

Designed for precise, high-performance motor control, the FR-A840-00380-2-60 is a variable frequency drive belonging to the premium Mitsubishi Electric FR-A800 series. This three-phase inverter provides dynamic vector control and high torque capability, making it well-suited for demanding heavy-duty industrial applications. Operating on a 400/415V AC input voltage, it features dual rating capabilities to maximize operating efficiency depending on load characteristics.

The unit incorporates an integrated Mitsubishi L-Series PLC with up to 6K steps of program memory, allowing users to implement decentralized control schemes directly within the drive. Backwards compatibility with the legacy FR-A700 series ensures minimal system downtime during upgrades. For communication and commissioning, the drive features a built-in USB Type A port, standard support for SSCNet, and direct plug-and-play interfacing with Mitsubishi GOT2000 HMIs.

Features

• Real Sensorless Vector Control and Closed-Loop Vector Control up to 400 Hz.
• Built-in Mitsubishi L-Series PLC functionality with up to 6K steps program memory.
• Dual-rating system optimized for both Constant Torque and Variable Torque loads.
• Optimum Excitation Control technology, reducing motor energy consumption by up to 12%.
• Integrated temperature sensor for continuous thermal monitoring and preventative maintenance.
• Support for external 24V DC control circuit power to maintain diagnostics and communications during main line isolation.
• Equipped with an integrated brake chopper for effective regenerative braking up to 55kW.
• Password-protected parameter configurations and PLC programs to safeguard intellectual property.

Applications

• Winding and unwinding machinery requiring high-precision tension control.
• Crane hoisting, gantry, and travel drives.
• Machine tool spindles and high-speed positioning units.
• Conveyor networks and continuous material handling equipment.

Installation Guidelines

When mounting the FR-A840-00380-2-60, ensure it is oriented vertically on a flat, non-flammable surface. Maintain a minimum vertical clearance of 100 mm above and below the unit, and 50 mm clearance on either side to allow proper heat dissipation from the cooling fans. Wiring must be routed inside dedicated, grounded metallic conduits to minimize electromagnetic interference (EMI). Always ensure a solid, low-impedance system ground is connected directly to the drive ground terminal.

Compliance and Certifications

• Functional Safety: PLd (EN ISO 13849-1) and SIL2 (IEC 61508) as standard.
• CE compliant.
• UL listed and cUL certified.
