Mitsubishi Electric FR-A820-1.5K FREQROL-A800 Variable Frequency Drive

Description

To manage demanding motor control challenges in modern production environments, the FR-A820-1.5K variable frequency drive from the Mitsubishi Electric FREQROL-A800 series provides highly adaptable vector control performance. Configured for three-phase 200V class operations, this inverter supports multiple operating duty ratings (SLD, LD, ND, HD) to match specific torque and load characteristics. Integrating advanced magnetic flux vector control alongside real sensorless vector control, it achieves high precision speed and torque regulation without requiring physical speed encoders under standard operations.

The unit features versatile communication capabilities, permitting integration with network topologies like CC-Link, CC-Link IE Field, DeviceNet, PROFIBUS-DPV0, and Modbus RTU. Designed for longevity and reliable deployment, it contains built-in diagnostic and protection circuits that prevent damage from overcurrent, overvoltage, and thermal overloads, ensuring operational continuity in harsh environments.

Features

• Multi-Rating Architecture: Supports Super Light Duty (SLD), Light Duty (LD), Normal Duty (ND), and Heavy Duty (HD) configurations to optimize performance for varied load profiles.
• Advanced Control Algorithms: Selectable V/F control, advanced magnetic flux vector control, real sensorless vector control, and PM sensorless vector control.
• Integrated Protection Suite: Protection against overcurrent, regenerative overvoltage, motor overload, fin overheating, input/output phase loss, and short circuits.
• High Carrier Frequency PWM: Employs Soft-PWM control to minimize acoustic motor noise and optimize operating efficiency.
• Extensive Dynamic Interfacing: Equipped with 12 contact inputs, 5 open collector outputs, 2 relay outputs, and dual analog inputs for versatile system mapping.

Applications

• Pumping and industrial water management systems
• Conveyors, material handling, and logistics machinery
• Industrial fans, blowers, and HVAC systems
• Machine tool axes and general packaging equipment

Installation Guidelines

• Mounting Position: Install the inverter vertically onto a flat, vertical surface using M4 or M5 mounting screws to ensure proper performance of the cooling fan assembly.
• Heat Dissipation Clearances: Maintain at least 50 mm clearance on both sides and a minimum of 100 mm clearance above and below the unit to prevent thermal blockages.
• Vibration and Shock: Ensure the mounting site exhibits vibrational forces below 5.9 m/s² (10 to 55 Hz in X, Y, and Z directions).
• Power Line Protection: Install appropriate circuit breakers or fast-acting fuses upstream from the R/L1, S/L2, and T/L3 power inputs to guard against short circuits.
