Specification

The Omron 3G3MX2-A2055-E is a robust, 5.5 kW variable frequency drive (VFD) in the MX2 series, designed to optimize energy efficiency and motor performance in demanding industrial environments. This AC drive features a 200-240 VAC, 3-phase input, delivering a rated output current of approximately 24 A at 5.5 kW for standard induction motors. It supports both V/f and sensorless vector control modes, enabling precise speed and torque regulation even at low speeds, with a starting torque of 150% at 0.5 Hz. The unit includes a built-in dynamic braking transistor (rated for 100% braking torque), an integrated EMC filter for compliance with EN 61800-3, and a protective IP20 enclosure suitable for clean, dry control cabinets. Communication via RS-485 Modbus RTU allows easy integration with Omron PLCs and SCADA systems. The drive also features a multi-function digital keypad with a 4-digit LED display, 8 programmable digital inputs, 2 analog inputs (0-10 VDC / 4-20 mA), 2 relay outputs, and 1 analog output. Overload protection is rated at 150% for 60 seconds, with a carrier frequency adjustable from 2 to 15 kHz. The 3G3MX2-A2055-E is ideal for applications such as conveyor belts, centrifugal pumps, and small HVAC fans, offering energy savings and smooth start/stop control.
