Product Overview
The Omron 3G3MX2-AB007-V2 is the 0.75 kW single-phase-input variant of Omron's MX2-series multi-function compact inverter, designed for use where only single-phase 200-240 VAC mains is available (typical residential / light-commercial installations in EU/US/JP) but a three-phase 230/460 VAC motor is required. It is manufactured by Omron Corporation. Hengyixin Automation ships this drive from Xiamen with the matching motor or PSU pairing recommended in the related products row below.
Single-phase 200-240 VAC ±10 % input at 50/60 Hz Output: three-phase 200-240 VAC variable frequency, 0.5 to 590 Hz Single-phase 200-240 VAC ±10 % input at 50/60 Hz Output: three-phase 200-240 VAC variable frequency, 0.5 to 590 Hz
Single-phase 200-240 VAC ±10 % input at 50/60 Hz Output: three-phase 200-240 VAC variable frequency, 0.5 to 590 Hz
This is the firmware revision that brought MX2 in line with Siemens G120C / Allen-Baldor VS1SD feature parity.
Key Features
- Single-phase 200-240 VAC ±10 % input at 50/60 Hz
- Output: three-phase 200-240 VAC variable frequency, 0.5 to 590 Hz
- Integrated EMC filter — no external line filter needed under 100 A supply
- V/f control
- SKU: 3G3MX2-AB007-V2
- Series: 3G3MX2 MX2-Series Multi-Function Compact Inverter, V2 firmware
- Voltage: 200 TO 240 VAC
Best-Fit Applications
- Conveyor-belt speed control in a small packaging line — 0.75 kW three-phase induction motor driven by 3G3MX2-AB007-V2, run command from.
- Fan / blower speed control on an HVAC unit — 0.75 kW three-phase fan motor with single-phase 200V supply, PID.
- Pump pressure control in a water-treatment skid — 0.75 kW centrifugal pump with PID on pressure transmitter, sleep-mode function to.
Buying Checklist
- Pick 3G3MX2-AB015-V2 for 1.5 kW single-phase 200V VFD — for slightly larger single-phase-supplied installations
- Pick 3G3MX2-AB004-V2 for 0.4 kW single-phase 200V VFD — for smaller conveyor and pump motors
- Pick 3G3MX2-AB022-V2 for 2.2 kW single-phase 200V VFD — maximum single-phase size before bridging concerns

FAQ for 3G3MX2-AB007-V2
What does the V2 firmware add over the original 3G3MX2-AB007 (V1)?
The V2 firmware revision added three significant features beyond the original V1: (1) sensorless vector control (open-loop vector control using the motor's electrical model to estimate rotor flux angle, delivering 200 % of rated torque at 0.5 Hz for low-speed high-torque applications like hoists and mixers — V/f control needs an encoder to do the same); (2) PM (permanent-magnet) motor open-loop control, including standstill start capability, for sinusoidal-back-EMF brushless motors without requiring an encoder (the drive reads the rotor's resting.
Can a single-phase-input VFD really drive a three-phase motor?
Yes — that's the entire purpose of the AB family (and the equivalent 240V series from other VFD vendors). The drive's input rectifier stage accepts single-phase AC and produces a DC bus (~ 280-340 VDC for a 200V input); the inverter section synthesizes three-phase AC at variable frequency from the DC bus via three pairs of IGBTs (one high-side and one low-side per phase).
What is sensorless vector control and when do I need it?
Sensorless vector control is a motor-control algorithm that estimates the rotor's magnetic flux angle from the motor's electrical model (winding resistance, inductance, and measured current/voltage). With the rotor angle known, the drive can control torque and flux independently — delivering rated torque at zero speed and holding the motor shaft against a constant load without rotating.
How do I wire Modbus RTU to the 3G3MX2-AB007-V2?
Wire the 3G3MX2-AB007-V2's RS-485 Modbus terminal block as follows: terminal SP (Send-Positive) → cable shield via twisted pair to PLC / HMI / master RS-485 device A terminal; terminal SN (Send-Negative) → cable shield via twisted pair to master RS-485 device B terminal; terminal RP (Receive-Positive) → not used on this drive (only on 3G3MX2 with dual RS-485 ports); terminal SN → connects to common ground; on multi-drop configurations (up to 32 slaves per master), add a 120 Ω termination.
