Customised to your machine

Design and integration costs are often higher than the costs of the equipment hardware.  When developing the RX inverter drives, Omron recognised that along with quality and reliability, the ability to easily and quickly customise the inverter to your application is critical.

By combining ease of use with a series of standard on-board application specific functions makes the RX suitable for a wide range of high performance inverter applications up to 132 kW 400 V a.c. three phase.

Superior motor performance

RX offers superior motor performance by operating in either open or closed loop mode. In sensorless vector mode, 200% starting torque is available at speeds as low as 0.3 Hz, and in closed loop mode, with the option card fitted, full torque is available down to zero speed.

These make the RX series ideal for a full range of applications including conveyors, mixers, hoists, pumps and many more.

Application functionality

The RX series is pre-programmed with specific application functionality. Brake control, positioning and electronic line shaft synchronisation are included as standard to enable you to develop the solution in the shortest time.Application functionality

For example, simple positioning is handled by the inverter without the need for an external controller. Functions include homing and position teaching.

RFI filter built-in

All 400 V a.c. RX series drives have a EN61800-3 cat C2 RFI filter built-in, which saves on space and cost when compared to externally mounted filters.

Automatic energy saving function

When inverter drives are used to control flow applications such as fans and pumps, which can generally accept a reduction in motor speeds, significant energy savings can be achieved. See article on the cube law for more information.

In addition to these savings, inverters such as the RX will always adopt the optimum energy saving setting for the application, thereby potentially providing additional cost savings.

Integrated solution

For basic networking applications, a Modbus RS485 interface is built into the RX drive.  This makes it easy to integrate into a system, with PLC, HMI, temperature controllers etc. The user then has access to all aspects of the device, and can change programming at the touch of a button.  In addition to Componet, a wide range of communications modules such as Profibus DeviceNet and EtherCAT can also be accommodated.

Other features include:

– Double rating VT 120%/1 min and CT 150%/1 min

– Built-in logic programmability

– Built-in application functionality
