1-1 Overview of Functions
The High-function General-purpose Inverter (Model: 3G3RX2) is a human- and environmental-friendly
inverter suitable for a variety of applications. It provides various features, such as convenient functions
intended for ease of use and diverse I/O. In addition, the 3G3RX2 Series complies with safety stan-
dards for any nations such as IEC Standard. You can use this product as a world standard inverter.
The 3G3RX2 Series Inverter has the following features.
The 3G3RX2 Series provides high performance and high functionality, which are the requirements of a
general-purpose inverter. It enhances the capability to support applications and addresses diverse
needs with optimal performance.
 Adoption of the Triple Rating Function (Normal Duty, Low Duty and Very Low
Duty)
At 3G3RX2 the previous heavy and light load modes were renewed to Normal Duty (ND), Low
Duty (LD) and Very Low Duty (VLD) to provide the triple rating function.
The Low Duty is available for a fan, pump, or other device that operates at the rated motor torque or
less in a normal state. Setting the Low Duty causes the rated current of the inverter to increase,
enabling the inverter to drive a motor that is one size larger in capacity.
However, pay attention to when selecting an inverter because the overload capacity decreases to 1
minute, 120% of the rated current.
Precautions for Correct Use
Switching the Normal, Low and Very Low Duty changes the setting ranges and default data
of the related parameters. Refer to 6-1-1 Inverter Load Rating Settings on page 6-3 for details.
 Implementation of the Programming Function
The 3G3RX2 Series has the built-in simple sequence function (DriveProgramming), which enables a
stand-alone inverter to perform simple sequence control.
You can create programs easily in flowchart or text language method by using the CX-Drive.
For details, refer to the DriveProgramming User’s Manual (Cat. No. I622).
 Implementation of the Vector Control Functions
With sensorless vector control, the inverter realizes a high starting torque at 200% of the motor rat-
ing in 0.3 Hz.
With 0-Hz sensorless vector control, the inverter can also output a high starting torque at 150% of
the motor rating in even lower frequencies.
The inverter has various vector control functions as listed below, in addition to V/f control.
• Sensorless vector control
• 0-Hz sensorless vector control
• Sensor vector control
