Product Overview
The 3G3MX2-A4110-V2 is the 11 kW step in Omron's MX2 V2 lineup — sitting between the 7.5 kW A4075-V2 and the 15 kW A4150-V2 in the 400V three-phase class. The -V2 suffix matters: it identifies the 2024 firmware revision with updated motor auto-tune algorithms and improved low-speed torque. Non-V2 (legacy) drives are still in the field and Omron continues to support them, but new installations should use V2. In normal duty (ND) the A4110-V2 drives 11 kW motors at constant torque; in light duty (LD) it can drive 15 kW motors at variable torque (fans, centrifugal pumps). The rated output current is 24.0 A in ND / 31.0 A in LD. Sensorless vector control gives decent low-speed torque without an encoder feedback card — adequate for most conveyor and pump applications, but for precise low-speed servo-grade holding, you'd step up to a servo drive (R88D-KN or 1S-series). On the input side, the drive takes 3-phase 400 VAC at 50/60 Hz. IP20 rating means panel-mount only — for washdown or outdoor, you need a separate enclosure. For EU CE compliance with harmonic current limits, Omron recommends a 3G3AX-NFI21 line input reactor in front of the drive, sized to the 24 A continuous current. Programming is done via the digital operator on the front panel (basic) or via the CX-Drive / Sysmac Studio software over USB (recommended for parameter backup and cloning). Common commissioning parameters to check: A001 (control source — terminal vs keypad), A002 (run source), b001 (accel time), b002 (decel time), and C001–C007 (multi-function inputs). A common pitfall: the A4110-V2 is rated for 11 kW continuous, but peak load (high inertia start, sticky material) can trip the drive. Set b003 (overcurrent level) to 150% and use the b004 (overcurrent time) parameter to allow the motor to come up to speed. For decel braking, the A4110-V2 has a built-in braking transistor but no braking resistor — you must add a 3G3AX-RB1500 or equivalent external resistor for fast decel of high-inertia loads.

FAQ for 3G3MX2-A4110-V2
What's the difference between 3G3MX2-A4110-V2 and 3G3MX2-A4110-EV2?
The -V2 is the standard model with no EMC filter; the -EV2 has a built-in EN 61800-3 category C2 EMC filter. For EU installations where the drive sits in a residential or light-industrial environment, the -EV2 saves you from buying an external line filter. For industrial panels with their own filtering, the -V2 is the cheaper choice.
Does the 3G3MX2-A4110-V2 need a braking resistor?
For most pump and fan applications (low inertia, gentle decel), no. For high-inertia loads like large flywheels, conveyors running downhill, or rapid-stop applications, yes — the drive has a built-in braking transistor but the resistor is external. Use a 3G3AX-RB1500 or equivalent, sized for the decel energy.
Can the A4110-V2 control a 15kW motor?
Yes, in light-duty (LD) mode the drive is rated 15kW variable torque. Set the drive to LD via parameter C027 = 1, then re-enter motor nameplate data. The drive will accept a 15kW motor on a fan or centrifugal pump where the torque curve is quadratic. Do not use LD with a 15kW constant-torque load like a compressor.
How do I program sensorless vector control on the MX2?
Set A044 = 1 (sensorless vector), then run auto-tune via the motor nameplate data. The drive measures stator resistance and saves it. After auto-tune, low-speed torque typically improves 30–50% vs V/f mode. For applications needing full torque at zero speed, you need an encoder feedback card and a different drive family.
