1-1 Overview of Functions
The Multi-function Compact Inverter (Model: 3G3MX2- -V1) provides a variety of functions such as
PM motor control and simple position control. It is also designed for open field networks to extend appli-
cation usability.
In addition, the 3G3MX2-V1 Series complies as standard with both the EC Directives and UL/cUL Stan-
dards. You can use this product as a world standard inverter.
The 3G3MX2-V1 Series Inverter has the following features.
Although this inverter is compact, it provides high functionality for enhanced application support and
addresses diverse needs with optimal performance.
z PM motors
In addition to conventional induction motors, this inverter provides the PM motor mode that supports
highly efficient PM motors, which results in more efficient control than the conventional energy-
saving control.
This is combined with the OMRON’s unique auto-tuning function and initial pole position estimation
function that estimates the magnetic pole position of a PM motor during startup to enable its smooth
start.
This control is suitable for applications with reduced torque characteristics (which do not require
torque at low speeds) such as fans and pumps.
However, it cannot be used for applications with constant torque characteristics such as general
transfer equipment and elevating axes, where the starting torque exceeds 50% of the rated motor
torque.

Implementation of the dual rating function
This inverter has the dual rating function that consists of the heavy load mode and the light load
mode.
This enables the efficient utilization of the inverter depending on your application.
• Heavy load mode
The heavy load mode is used for a transfer machine, elevator, or other device that temporarily
requires a torque exceeding the rated torque. This mode enables high torque control similar to
that achieved with the previous product.
The overload capacity is 150% of the rated current for 1 minute.
• Light load mode
The light load mode is used for a fan, pump, or other device that operates at the rated motor
torque or lower.
Setting the light load mode causes the rated current of the inverter to increase, enabling the
inverter to drive a motor whose capacity is one size larger.
However, check when selecting an inverter because this also decreases the current overload
capacity to 120% of the rated current for 1 minute.
