Omron 3G3MX2-AB022-ZV1 Compact Inverter

The Omron 3G3MX2-AB022-ZV1 belongs to the MX2 series of compact AC drives, renowned for high torque at low speeds via sensorless vector control. It is designed for single-phase or three-phase 200V input and delivers 2.2kW (3HP) to three-phase induction motors.

Key Specifications

• Input: 200–240V AC, 50/60Hz (single or three-phase)

• Rated output current: 12.0 A

• Overload capacity: 150% for 60 seconds, 200% for 3 seconds

• Control method: V/f, sensorless vector, PM motor control

• Frequency resolution: 0.01 Hz

• Built-in EMC filter (Class C2)

Sensorless Vector Control

This drive provides 200% starting torque at 0.5 Hz, enabling smooth acceleration of high-friction loads. Auto-tuning automatically identifies motor parameters for optimal vector performance. It also supports permanent magnet synchronous motors (PMSM), improving efficiency in fans and pumps.

Communication and I/O

Standard RS-422/485 port (Modbus RTU). Optional fieldbus: PROFIBUS, DeviceNet, CANopen, CC-Link. It features 7 digital inputs, 1 analog input (0-10V, 4-20mA), 1 analog output, and a relay output (SPDT). A built-in PID controller with sleep function is ideal for pump applications.

Programming and User Interface

The drive includes a simple LED keypad with potentiometer for speed adjustment. Parameter backup/restore can be done using the optional CX-Drive software. Up to 16 preset speeds, 2 acceleration/deceleration ramps, and S-curve profiles are available.

Protections

Overcurrent, overvoltage, undervoltage, overheating, and ground fault protection. The drive also features electronic thermal relay (I²t) and stall prevention during acceleration/deceleration.

Environmental and Compliance

IP20 enclosure (open type), operating temperature -10°C to 50°C. Vibration resistance 5.9 m/s² (0.6G). Certified with CE, UL, cUL, and RoHS.

Typical Applications

Used in small conveyors, fans, pumps, packaging machines, woodworking equipment, and textile machinery. Its compact size (width 108mm, height 128mm, depth 170mm) fits space-limited panels.

Conclusion

The Omron 3G3MX2-AB022-ZV1 offers high-performance motor control in a cost-effective package, combining sensorless vector torque, multiple communication options, and robust construction.
