Description

Optimizing industrial motor drive efficiency, the Mitsubishi Electric FR-A840-02600-2-60 functions as a high-capacity variable frequency drive within the premier FR-A800 Series. This unit provides exceptional vector control performance and is built specifically for three-phase 400V class applications. Equipped with conformally coated circuit boards (Class 3C2), it offers robust defense against harsh ambient environments containing dust or corrosive gases, though it does not utilize plated conductors. With an SLD (Super Light Duty) rating of 260A, it is engineered for precise speed and torque regulation of induction and permanent magnet motors in heavy industry.

Features

Advanced Real Sensorless Vector Control and Vector Control for ultimate motor response and speed accuracy.
Conformally coated circuit boards conforming to IEC 60721-3-3 Class 3C2 for increased environmental resilience.
Built-in PLC functionality allowing customized program execution and standalone machine control.
Integrated Safety Torque Off (STO) functional safety compliance to minimize system downtime.
Energy-saving tuning algorithms that optimize excitation currents according to real-time load requirements.

Applications

Large-scale pump and fan systems requiring precise flow and pressure regulation.
Heavy-duty conveyor lines and material handling machinery.
Extruders, mixers, and centrifuges in chemical and plastics processing.
Hoists, cranes, and gantry systems requiring precise low-speed torque control.

Empirical Engineering Insights

Alternative Models & Compatibility

When upgrading from legacy FR-A740 series drives, parameter conversion can be performed seamlessly via FR Configurator2 software. Be aware that the physical footprint and mounting centers of this 58 kg chassis may differ slightly from older generations. Always verify enclosure depth limits to accommodate the cooling fan projection.

Application Pitfalls & Engineering Notes

Due to its high power rating, heat dissipation must be carefully planned. This unit rejects significant thermal energy under full-load operation. In enclosed electrical panels, forced exhaust ventilation or air conditioning is mandatory to keep ambient air surrounding the inverter below 50 degC. For high-inertia loads, a dynamic braking resistor or regenerative unit must be correctly sized to avoid overvoltage trips (E.OV3).

Commissioning & Wiring Tips

Ensure the input power factor correcting DC reactor (FR-HEL) is installed if compliance with harmonic guidelines is required. Terminal layout control wiring must be run in shielded twisted-pair cables, keeping low-voltage analog cables separated from 400V motor and mains cables by at least 30 cm to prevent EMI noise coupling. Set parameter 9 (Electronic Thermal O/L Relay) matching the exact motor nameplate current immediately upon initial power-up.

Installation Guidelines

CRITICAL WARNING: Ensure all primary AC power sources are completely de-energized and locked out before attempting installation or maintenance. Wait a minimum of 10 minutes after input power disconnect to allow the high-voltage DC bus capacitors to discharge safely. Measure DC bus voltage across terminals P/+ and N/- to verify it is below 45V DC before making contact with terminal connections.

Mount the inverter vertically to a rigid, flat, and non-flammable vertical backplate to allow natural heat rising and effective forced-fan convection.

Connect input power lines to R/L1, S/L2, and T/L3. Connect motor cables to U, V, and W terminals. Ensure proper earth grounding to the dedicated PE terminal to reduce stray leakage currents.

Wire control circuit terminals according to application requirements, keeping analog reference inputs separate from high-current AC cabling.

Securely fasten the terminal cover, restore input power, and proceed with auto-tuning parameters via the integrated parameter unit keypad or FR Configurator2.

#FR-A800 Inverters #Variable Frequency Drives

What is the meaning of the -60 suffix on this VFD?

The -60 suffix indicates that the drive's control boards have a conformal coating conforming to Class 3C2 (IEC 60721-3-3) for environmental defense against gases and moisture, and it is built without plated conductors.

What are the power and voltage capabilities of this unit?

This is a 400V class inverter designed for three-phase AC supplies between 380V and 500V. It features a Super Light Duty (SLD) output current rating of 260A.

Does this drive require any special venting configurations?

Yes. Due to its 58 kg weight and high thermal output, it requires forced-air ventilation inside enclosed electrical cabinets to maintain ambient temperatures below 50 degC.

Can this inverter be used to replace older FR-A740 models?

Yes, it can replace equivalent capacity FR-A740 models. Parameters can be imported and converted using Mitsubishi Electric's FR Configurator2 software.
