Omron’s versatile RX variable speed drives provide the high performance and advanced functions demanded in a general-purpose inverter, and enable the 3G3RX series to meet most of your needs.

Simple Positioning Control with the Inverter

Simple positioning control can be handled by the Inverter, which costs less than a servo system. This also means that you can replace servo systems with Inverters in applications where high-speed, high-precision positioning is not required.

Position commands, speed commands, and acceleration/deceleration times are set in parameters to perform up to 8-step positioning. The Teaching Function can also be used to store positioning points in memory by actually moving the machine. There are two types of positioning motions to select from: positioning commands with absolute values and interrupt feeding.

Automatic Energy-saving function

This function automatically minimizes the Inverter output power during constant speed operation. It has a large energy-saving effect when used with fans and pumps.

Vector Control

To enable the inverter to produce a 200% starting torque at 0.3 Hz, the 3G3RX include the following control methods:

– Sensorless vector control
– Sensorless vector control in O Hz domain
– Vector control with a encoder feedback

PID Control

PID control allows the Inverter to control equipment such as fans and pumps using temperature, pressure, flow-rate and other process amounts, without the need for external devices like Temperature Controllers.

Momentary Power Interruption Restart

When there is a momentary power interruption during operation, the motor will smoothly restart instead of coasting to a stop.

Stall prevention

When rapid acceleration or a change in the load results in a sudden over-current, the Over-current Suppression Function automatically limits the output current to ensure that steady operation continues.

Braking process

All models of 22 kW or less are provided with the Braking Process Function as standard equipment. This function shortens motor stopping time by 30% without the use of braking resistors, and controls applications that are subject to sudden acceleration or stopping.
