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.
| Manufacturer | Mitsubishi Electric |
| Model Number | FR-A840-05470-2-60 |
| Input Voltage Class | Three-Phase 380V to 500V AC (50Hz / 60Hz) |
| Super Light Duty (SLD) Current | 547 A |
| Light Duty (LD) Current | 442 A |
| Normal Duty (ND) Current | 361 A |
| Heavy Duty (HD) Current | 288 A |
| Equivalent Motor Rating (SLD) | 280 kW |
| Equivalent Motor Rating (HD) | 160 kW |
| Board Conformal Coating | With Coating (IEC 60721-3-3 Class 3C2 compliant) |
| Plated Conductor | Without Plating |
| Cooling Mechanism | Forced Air Cooling |
| Enclosure Protection Rating | IP00 (Open Type) |
| Operating Ambient Temp. | -10 degC to 50 degC |
| Shipping Weight | 170 kg (374.8 lbs) |
| Terminal Block | Terminal Label | Signal Description & Specification |
|---|---|---|
| Power Terminals | R/L1, S/L2, T/L3 | Main power supply AC input (3-phase, 380V to 500V) |
| U, V, W | Output terminals to 3-phase induction or PM motors | |
| Control / Feedback | A, B, C | Relay output terminals (Fault signaling, AC 230V / DC 30V limit) |
| S1, S2, SIC | Safety stop input circuit (STO function compliance) |
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.
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).
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.
