The Omron 3G3MX2-A4055-ZV1 is a multi-function compact inverter from the MX2 series, sized for 3-phase 400 V AC supplies and rated to match an 11 kW motor on the constant-torque (CT) duty curve. It is built as a panel-mount or closed wall-mount drive with an IP10 minimum enclosure rating, so it lives inside a cabinet rather than out on the machine skin. Voltage class 4 denotes 3-phase 400 V AC; maximum applicable motor capacity is 11 kW on the CT rating. Match the driven motor's nameplate kW to that 11 kW CT figure before adding it to the BOM.
What to check before it lands on the BOM
Confirm the motor's full-load amps and the application duty cycle against the CT rating, then match the braking resistor sizing if the load profile includes vertical axes or short decel ramps — the MX2 platform handles sensorless vector control down to low speeds, but regen energy still needs somewhere to go. For cabinet layout, leave the heatsink path clear and respect the panel-mount IP10 minimum, which means a dust-tight enclosure is the installer's responsibility, not the drive's.
