Product Overview

The Omron 3G3MX2-A4075-V2 is a 7.5 kW (10 HP) variable frequency drive from the MX2 series, engineered for three-phase 380–480 VAC industrial motors. It combines high-performance vector control with a compact footprint and built-in safety, making it well suited to pumps, fans, conveyors, mixers, and general-purpose machine automation.

Drive control modes include V/f, sensorless vector, and closed-loop vector with optional encoder feedback card, supporting both constant-torque and variable-torque loads. The integrated Safe Torque Off (STO) function meets SIL3 / PLe per IEC 61800-5-2, allowing the drive to be used in safety-related stop functions without additional contactors.

An integrated EMC filter (C3) reduces conducted emissions for industrial environments, and the detachable LED keypad supports parameter upload/download for fast commissioning of multiple drives. Built-in Modbus RTU is standard; optional communication cards add EtherNet/IP, DeviceNet, PROFIBUS-DP, and CompoNet.

Comprehensive motor protection covers overload, overvoltage, undervoltage, overcurrent, ground fault, output phase loss, and heatsink overtemperature. The built-in brake chopper accepts an external braking resistor for dynamic-stop applications.

Best-Fit Applications

  • Centrifugal pumps and water-treatment skid control
  • HVAC supply / return fans, AHU and chiller fans
  • Conveyor systems in packaging and material handling
  • Mixers, agitators, and blenders in process industries
  • Compressors and dryer blowers
  • Machine-tool spindle drives
  • General industrial motor speed control up to 7.5 kW

Buying Checklist

  • Confirm supply: three-phase 380–480 VAC; for 200 V class use AB-series, for single-phase input use AB- or A2-series.
  • Verify motor FLA is within 17.5 A (ND) / 15 A (HD) at 400 V.
  • Plan for an external braking resistor if the application requires dynamic braking or fast deceleration.
  • Select encoder feedback card if closed-loop vector control is required.
  • Order optional comms card (EtherNet/IP / DeviceNet / PROFIBUS) if the PLC network requires it.
  • Install on a panel with adequate clearance for cooling airflow; ambient must stay below 50 °C (ND).

FAQ for 3G3MX2-A4075-V2

What size breaker and wiring does the 3G3MX2-A4075-V2 need?
Use a 25 A type-D or K circuit breaker on the input side, sized at 150–200 % of VFD input current to absorb inrush. Run shielded motor cables and keep them separated from signal wiring. Always include a line-side contactor driven by the safety circuit for emergency-stop compliance.
Can this VFD run from single-phase input?
No — A4 models require three-phase input. For single-phase 200 V supply use the 3G3MX2-AB015-V2 (200 V class single/three-phase input, derated). For 400 V single-phase input, use a step-up transformer or select a different MX2 model.
Does the 3G3MX2-A4075-V2 include STO?
Yes — Safe Torque Off is built in and rated SIL3 / PLe per IEC 61800-5-2. It removes drive output torque within milliseconds of the safety input opening, allowing integration into category-3 / PL d and higher stop functions without external contactors.
What braking options are available?
The drive includes a built-in brake chopper. Connect an external braking resistor sized to the application's deceleration energy and duty cycle. For vertical-axis holding, add an electromagnetic brake on the motor — the drive does not provide mechanical holding.
Can I use the 3G3MX2-A4075-V2 for pump pressure control?
Yes. The built-in PID controller maintains constant pressure, flow, or level using a 4–20 mA or 0–10 V transducer. Typical energy savings versus valve-throttling are 30–50 %. Sleep / wake and multi-pump lead-lag functions are supported via the MX2's application macro library.
