Description

To facilitate precision motor control in heavy-duty machinery, the Mitsubishi Electric FR-A840-05470-2-60 is engineered as a three-phase 400V variable frequency drive within the high-performance FR-A800 Series. This high-capacity inverter features a multi-rating design that allows operations across Super Light Duty (SLD), Light Duty (LD), Normal Duty (ND), and Heavy Duty (HD) profiles, optimizing performance based on load requirements. Equipped with a 3C2 conformal board coating for enhanced atmospheric resilience, this unit operates reliably in harsh industrial environments without plated conductors.

Features

Quadruple Rating System: Configurable ratings allow one VFD to adapt to different load demands, maximizing motor compatibility up to 280 kW.
Conformal Coating (3C2): Internal control and power printed circuit boards are coated to protect against corrosive gases and industrial particulates.
Advanced Vector Control: Supports Real Sensorless Vector (RSV) control, vector control with encoder feedback, and PM sensorless vector control.
Safety Integration: Features built-in Safe Torque Off (STO) functionality to meet basic machinery safety standard regulations.
USB Host Interface: Direct parameter copy and trace data diagnostics via integrated USB ports using standard flash drives.

Applications

Heavy-duty municipal and industrial water treatment pumps.
Large-scale ventilation fans and air handling units.
High-inertia material handling conveyors and crane hoist controls.
Industrial extruders, mixers, and processing centrifuges.

Empirical Engineering Insights

Alternative Models & Compatibility

This unit is the direct functional replacement for the older generation FR-A740-05470 frequency inverters. If migrating from the A700 series, you can import settings directly via FR Configurator2 software. Please note that physical footprint differences and terminal orientations require verify panel space allocations, as mounting adapters may be necessary for retrofit enclosures.

Application Pitfalls & Engineering Notes

At full SLD rating (547A), internal losses generate significant thermal dissipation. If installing this unit inside an enclosed cabinet, the enclosure design must accommodate forced external air extraction or clean air intake systems. Running this drive in temperatures consistently exceeding 40 degC without setting correct derating profiles will trigger premature overtemperature warnings (E.THT / E.FIN faults).

Commissioning & Wiring Tips

Due to the high switching frequencies and large output currents, utilizing symmetrical shielded symmetrical three-phase motor cables is mandatory to prevent electromagnetic interference (EMI) with control instrumentation. Ensure the shield is terminated 360 degrees on both the drive-side gland plate and the motor junction box. High ground leakage currents are expected; ground conductors must conform strictly to local electrical codes for high-current hardware.

Installation Guidelines

CRITICAL WARNING: Hazardous voltage levels are present on internal DC bus terminals for up to 10 minutes after main supply de-energization. Verify that the charge indicator LED on the front chassis is completely extinguished and use a calibrated digital multimeter to measure and confirm 0V across DC bus terminals before making physical contact with any electrical terminals.

Ensure vertical orientation on an unpainted, flat, non-flammable back panel to optimize airflow and drive chassis grounding.

Connect the main AC input lines to power terminals R/L1, S/L2, and T/L3, ensuring correct phase configuration.

Verify torque specifications on all main circuit power terminals before restoring primary input power.

#FR-A800 Series #Variable Frequency Drives

What is the physical significance of the -2-60 suffix in this model code?

The -2 suffix designates the CA (type) variant, while -60 indicates that the internal circuit boards feature a protective 3C2 conformal coating for harsh environments, but do not feature plated copper conductors.

Can this drive be used with Permanent Magnet (PM) motors?

Yes. This drive supports both induction motors and PM motors via built-in PM sensorless vector control, eliminating the need for an external encoder in many applications.

What are the continuous output current ratings across different duty cycles?

The continuous current output is rated at 547A for Super Light Duty (SLD), 442A for Light Duty (LD), 361A for Normal Duty (ND), and 288A for Heavy Duty (HD).
