Mitsubishi Electric FREQROL-D700 FR-D720-0.4K is a compact micro inverter for controlling three‑phase induction motors at 200‑240 V AC (single‑phase or three‑phase input). Rated output 0.4 kW (0.5 HP). Built‑in RS‑485 communication (Modbus‑RTU, Mitsubishi inverter protocol), general‑purpose magnetic flux vector control for enhanced low‑speed torque (150% at 1 Hz), and STO safety function (SIL2/PLd). Self‑cooling, IP20 enclosure. Designed for upgrading single‑phase equipment to variable speed control and for general three‑phase motor speed regulation in industrial automation.

Applications:

  • Conveyor speed regulation and material handling

  • Fan and blower speed control in HVAC systems

  • Pump speed control and fluid handling

  • Small packaging machinery and food processing equipment

  • General OEM machine automation

System Integration:

  • This inverter belongs to the Mitsubishi Electric FREQROL‑D700 series.

  • Converts single‑phase or three‑phase 200‑240 V AC input to three‑phase 200‑240 V AC output for standard three‑phase induction motors.

  • RS‑485 communication via PU connector supports Modbus‑RTU and Mitsubishi inverter protocol for parameter setting, monitoring, and control.

  • Parameter setting and monitoring via integrated digital dial/keypad, optional FR Configurator software, or FR‑PA07 enclosure surface operation panel.
