Description

Designed for demanding industrial motor control, the Mitsubishi Electric FR-A820-11K-1 variable frequency drive provides exceptional precision and dynamic torque response within the high-performance FREQROL-A 800 series. Operating on a three-phase 200V class input, this unit features flexible multi-rating capabilities (SLD, LD, ND, and HD) to match the exact overload profile of your machinery. Equipped with advanced magnetic flux vector control and real sensorless vector control, it achieves peak torque performance down to near-zero speeds, making it ideal for high-inertia startup applications.

Key Features

  • Four-Tier Overload Ratings: Configurable for Super Light Duty (SLD), Light Duty (LD), Normal Duty (ND), and Heavy Duty (HD) to maximize motor sizing and thermal efficiency.
  • Comprehensive Vector Control: Supports multiple control topologies including V/F control, advanced magnetic flux vector control, real sensorless vector control, and PM sensorless vector control.
  • Extended Network Integration: Seamlessly communicates over RS-485 and supports CC-Link, CC-Link IE Field, DeviceNet, PROFIBUS-DPV0, and Modbus RTU protocols.
  • Robust Protection Suite: Built-in safeguards against overcurrent, overvoltage, input/output phase loss, motor overload, and heatsink overheating.
  • IP20 Enclosure Rating: Closed-type protective structure designed for clean panel installation with efficient forced-air cooling.

Heavy Industrial Applications

  • Cranes, Hoists, and Elevators: Precise torque control and high starting torque at low speeds prevent load slippage.
  • Conveyors and Bulk Handling: Smooth S-pattern acceleration and deceleration limits mechanical strain on belts and gearboxes.
  • Extruders and Centrifuges: High-speed response and excellent speed stability under fluctuating load conditions.
  • Industrial Fans and Pump Systems: Energy-saving optimum excitation control adjusts output voltage dynamically to minimize current draw under variable torque loads.

Empirical Engineering Insights

Alternative Models & Compatibility

The FR-A820-11K-1 is the direct legacy replacement path for the older FR-A720-11K series. Mounting footprint dimensions remain highly compatible; however, if upgrading from an A720, utilize Mitsubishi FR Configurator2 software to extract and convert the parameter block. Be aware that the A800 series introduces a dedicated 24 VDC control circuit power input, allowing you to maintain communications and safety feedback even when primary three-phase power is disconnected.

Application Pitfalls & Engineering Notes

When sizing this drive for high-altitude environments, you must derate the output current by 1% for every 100 meters above 1000 meters sea level (up to a maximum of 2500 meters). To prevent nuisance overvoltage trips (E.OV3) during aggressive deceleration profiles, monitor Parameter 8 (Deceleration Time). If short stopping sequences are mandatory, install an external brake resistor connected directly across terminals P/+ and PR, and ensure Parameter 30 (Regenerative function selection) is configured correctly.

Commissioning & Wiring Tips

To configure analog terminal input behaviors, always verify the status of the voltage/current selection slide switches located behind the control terminal cover. For example, if Terminal 4 is used for a 4-20mA feedback loop, the hardware switch must match the corresponding firmware settings in Parameter 267. Always route your low-voltage control signals through a separate conduit from high-voltage motor output lines (U, V, W) to mitigate electromagnetic interference and potential signal drift.

Installation Guidelines

CRITICAL WARNING: HAZARDOUS VOLTAGE

Isolate all input power connections before mounting or servicing. Wait a minimum of 10 minutes after disconnecting source voltage to allow internal DC bus capacitors to discharge safely. Measure DC voltage across terminal points P/+ and N/-; ensure it is less than 30 VDC before performing physical installation work.

1
Ensure a vertical mounting orientation on a flat, non-flammable backplate, maintaining a minimum clearance of 50 mm above and below the drive to enable free convection and forced airflow.
2
Connect the physical system ground to the designated protective earth (PE) terminal. Avoid loops by grounding all motor shielding directly at the drive ground lug.
3
Confirm control card jumper configurations for sink or source logic to align perfectly with the target PLC input/output cards before powering the drive control circuit.

What are the output capacity ratings of the FR-A820-11K-1?

This inverter supports four-tier rating classes: Super Light Duty (SLD) at 15 kW, Light Duty (LD) at 15 kW, Normal Duty (ND) at 11 kW, and Heavy Duty (HD) at 7.5 kW.

How long must I wait after powering down before servicing this unit?

You must wait at least 10 minutes to allow the internal bus capacitors to discharge. Always measure the DC voltage across the P/+ and N/- terminals to ensure it is under 30 VDC before proceeding.

What is the frequency control range of the FR-A820-11K-1?

In basic V/F mode, the frequency output ranges from 0.2 to 590 Hz. When employing advanced vector or PM sensorless vector modes, the upper frequency limit is 400 Hz.

Can I use an external 24 VDC supply to power the control circuit separately?

Yes, the A800 series features dedicated terminals to accept an external 24 VDC control power input, maintaining safety circuits and diagnostics when main three-phase power is isolated.
