Why Engineers Specify This Model
- Ultra-Compact Footprint — Fits into tight control panels without sacrificing performance; ideal for retrofit projects with limited enclosure space.
- Low Acoustic Noise — High carrier frequency PWM reduces motor audible noise, critical for office-adjacent HVAC and medical facility applications.
- Single-Phase Input → Three-Phase Output — Enables three-phase motor operation from single-phase supply, eliminating the need for a phase converter in sites without three-phase infrastructure.
- Built-in EMC Filter — Reduces conducted emissions, simplifying CE compliance for machine builders exporting to European markets.
- Simple Parameter Setup — Intuitive digital operator with copy function accelerates commissioning and reduces downtime during replacement.
- OMRON Ecosystem Compatibility — Seamlessly integrates with OMRON PLCs (CP1, CJ2, NX series) via RS-485 Modbus RTU for centralized SCADA control.

Application-Specific FAQ
Q: Can the 3G3EV-AB007M-E run a 0.75 kW three-phase motor from a single-phase 220 V supply?
A: Yes. The AB007M-E variant accepts single-phase 200–240 V input and outputs three-phase voltage to the motor. This is one of its primary design advantages for sites without three-phase infrastructure.
Q: Is this inverter suitable for constant-torque loads like conveyors?
A: Yes, with proper derating. For continuous constant-torque duty below 30 Hz, ensure adequate motor cooling (forced ventilation or a motor with a separate cooling fan) and verify the drive’s thermal overload settings.
Q: What is the difference between 3G3EV-AB007M-E and 3G3EV-AB007?
A: The “-E” suffix denotes the export/international version with built-in EMC filter and CE/UL certification. The base model without “-E” may lack the integrated filter and is intended for the Japanese domestic market.
Q: Can I connect this drive to an OMRON PLC via Modbus?
A: Yes. With the optional RS-485 communication card, the 3G3EV supports Modbus RTU protocol, enabling speed reference, run/stop commands, and fault monitoring from any OMRON or third-party PLC/SCADA system.
Q: What spare parts should I stock for preventive maintenance?
A: Recommended spares include the cooling fan (if fan-cooled variant), electrolytic capacitors (service life ~10 years at 40°C), and the digital operator. Contact us for a preventive maintenance kit quote.
