Omron MX2 Series Inverters: 3G3MX2-A4110-ZV1 and 3G3MX2-A4150-ZV1

The Omron 3G3MX2-A4110-ZV1 and 3G3MX2-A4150-ZV1 are high-performance variable frequency drives from the acclaimed MX2 series. These inverters are designed to control three-phase induction motors with exceptional precision, energy efficiency, and dynamic response. Both models incorporate built-in PLC functionality, making them smart drives capable of executing logic sequences without an external controller.

Power Ratings and Specifications

The 3G3MX2-A4110-ZV1 is rated for 11 kW (15 HP) at 400 V class, while the 3G3MX2-A4150-ZV1 delivers 15 kW (20 HP). Both operate on a three-phase input voltage of 380-480 VAC, 50/60 Hz. The output frequency range is from 0.1 to 400 Hz, with a speed control accuracy of ±0.2% of base speed. Overload capacity is 150% for 60 seconds, ensuring robust torque for demanding loads.

Advanced Motor Control

These drives employ sensorless vector control and V/f control modes, allowing optimal torque and speed regulation across the entire speed range. Auto-tuning simplifies motor parameter identification, and the built-in braking transistor supports dynamic braking for rapid deceleration. The drives also feature energy-saving algorithms that reduce power consumption under partial load conditions.

Built-in PLC and Logic Capabilities

One of the standout features is the integrated PLC function, which supports up to 32 user-defined programs using ladder logic. This enables the drive to handle simple machine sequences, timing, and interlocking directly, reducing the need for separate PLC hardware. The logic engine runs concurrently with motor control, ensuring real-time responsiveness.

Communication and Networking

Both models include standard RS-485 Modbus RTU and optional fieldbus modules for Profibus, DeviceNet, EtherNet/IP, and CANopen. The drives can be networked in a daisy-chain or star topology, and they support parameter read/write via communication, enabling remote monitoring and control from a central SCADA system.

User Interface and Programming

A backlit LCD digital operator provides local control, parameter setting, and status display. The intuitive menu structure allows quick access to motor parameters, PID settings, and fault logs. The drives also support PC-based configuration software for offline programming and cloning of parameters across multiple units.

Applications

Typical applications include conveyors, fans, pumps, mixers, extruders, and cranes. The MX2 series is especially suited for industries such as food and beverage, plastics, textiles, and water treatment, where precise speed control and reliability are critical.

Protection and Environmental Durability

These inverters are protected against overcurrent, overvoltage, undervoltage, overload, and overtemperature. They have an ingress protection rating of IP20 (open type) and are designed for operation in ambient temperatures up to 50°C with derating. Conformal coating on PCBs enhances resistance to humidity and contaminants.

Installation and Commissioning

Mounting is via panel or DIN rail, with clear terminal markings for power, motor, and control wiring. Commissioning is facilitated by the auto-tuning routine and guided start-up wizard. The drives store fault history with time stamps, aiding in diagnostics and preventive maintenance.

In summary, the Omron 3G3MX2-A4110-ZV1 and 3G3MX2-A4150-ZV1 inverters offer a powerful combination of motor control and PLC logic, making them versatile building blocks for modern automation systems.
