The Omron 3G3RX-A4220-E1F is a high performance AC variable frequency drive (VFD) from the Omron RX inverter series, designed for precise speed and torque control of three-phase motors in demanding industrial automation applications. Built for machinery, process control and heavy-duty motor control, the RX range provides advanced drive functionality for applications requiring dependable performance and flexible configuration.
This inverter supports open loop and closed loop vector control, helping deliver accurate motor response, strong starting torque and smooth speed regulation across varied load conditions. Its built-in control features and automation-friendly design make it suitable for integration into PLC-controlled systems, industrial control panels and OEM machinery.
With a rated motor power of 22 kW, rated output current of 48 A and a three-phase 380–480 V AC supply, the 3G3RX-A4220-E1F is ideal for larger industrial motors used in conveyors, pumps, fans, compressors, mixers, hoists and production machinery. The IP20 cabinet-mounted format is intended for installation within protected electrical enclosures.
Variable frequency drives such as the Omron 3G3RX-A4220-E1F regulate motor speed by adjusting output frequency and voltage. This improves process control, reduces mechanical stress and can help lower energy consumption in applications where motors do not need to run continuously at full speed.
The RX series is designed for industrial users requiring robust motor control, strong torque characteristics and dependable operation across demanding machinery applications. With vector control capability and flexible parameter settings, the 3G3RX-A4220-E1F provides a reliable solution for both standalone equipment and integrated automation systems.
