Versatile general-purpose inverter

21 May 2019

Omron has launched a new series of high-performance frequency inverters to meet the changing demands of system integrators, machine builders and manufacturers. The RX2 series help ensure productivity, quality and reliability, along with easy customisation. The inverters are designed for applications such as filling control, press working and tension control, for both permanent magnet (PM) motors and induction motors.

As large companies in the EU carry out audits to searching for ways to reduce energy consumption, it is important to investigate each component and step in the production process for possible improvements. Omron responds to this need with innovative automation solutions that help companies and governments to achieve their energy-efficiency goals.

Inverters are used to control the frequency of power supplied to AC motors to adjust the rotation speed as well as acceleration of the motors, depending on the requirements of the application. At the same time, inverters can help ensure that processes are carried out in the most economical way possible.

Evolved heritage & easy replacement

The new RX2 series offers auto-tuning that maximises PM motor performance which, in turn, leads to energy savings. The double rating of its predecessor RX, which included the normal duty (ND) and heavy duty (HD) ratings, is now upgraded to triple rating. This makes it possible to use a single inverter for a wide range of motor applications, minimising footprint and maximising performance.

The RX2 series maintains the same mounting dimensions as the previous RX model, offering an easy replacement to existing control panel and mounting locations. In addition, the existing CX-Drive software can also be used. By utilising the same software, parameter settings and programmes used in previous models, it is easy to migrate to the new RX2 inverters.

Thanks to the built-in noise filter, which corresponds to the European EMC Directive (IEC61800-3 2nd Environment Category C3 and UL Power Conversion Equipment/UL61800-5-1), users do not need additional external hardware, avoiding further costs. The new full-colour LCD interface makes setup and operation intuitive and easy, while the parameter copy function allows users to quickly copy settings to other RX2 inverters. The RX2 inverter can also perform simple sequence control programmed using the CX-Drive support software.

Optimised costs, safety & connectivity

Crane control, tension control, and other large-scale processes that require fast control speeds can be configured without a PLC (Programmable Logic Controller), optimising costs. In addition, the RX2 features Safe Torque Off (STO) as a standard feature to meet machine safety needs. It is certified to IEC 61800-5-2:2016 STO SIL3 and ISO 13849-1:2015 Cat.4 PLe safety standards. The RX2 inverters can be connected to the NX and NJ machine automation controllers from Omron to improve development and production productivity (EtherCAT option coming soon).

“Our new RX2 inverters offer high performance. We strive for constant evolution with our inverters responding to market needs such as increased energy efficiency,” says Alberto Fuentes, European Drive Product Marketing Manager. “The RX2 is even more intuitive and faster to use than the previous RX models, and for existing customers, it couldn’t be easier to upgrade.”
