Frequency inverter drives are a key component of Mitsubishi Electric's factory automation systems. More than 30 years on and with over 14 million units sold worldwide, Mitsubishi Electric is still continually contributing innovations to variable-speed drive technology. The latest 64-bit RISC processors, advanced software models and the latest power electronics make today's variable-speed drive solutions from Mitsubishi Electric both powerful and easy to use. Mitsubishi Electric delivers innovative, open, flexible and reliable drive solutions geared to the special needs of individual markets and customers.

Mitsubishi frequency inverters satisfy all the standards and specifications of the European Union's 2006/95/EC directive on low-voltage equipment and the 2006/42/EG machinery directive. All products have a CE certificate subject to 89/336/EEC, and also UL, cUL and DNV certificates and the certification for the Russian market. All important protective functions are included as standard equipment, and all Mitsubishi frequency inverters conform to both the ISO 9001 quality standard and the ISO 14001 environment standard.

Energy saving and regenerating frequency inverters

Mitsubishi inverters are real energy savers achieving maximum drive capacity utilisation with minimum power consumption. Flux optimisation ensures that the connected motor only gets exactly the amount of magnetic flux required for optimum efficiency. This is particularly important at low speeds as motors are normally using a voltage/frequency control system. SLV Vector Control with Online Auto tuning and automatic slip compensation, V/f control with a fully-programmable characteristic and Mitsubishi Electric's advanced OEC (Optimium Excitation Control) technology all help to make these frequency inverters masters of energy conservation. They can achieve maximum power savings of up to 60% compared to conventional mains operation, thus minimising system operating costs.

The FR-A741’s regenerative braking system makes it much more efficient than conventional drive systems, giving it the potential for significant energy savings. They are particularly well suited for tasks involving frequent cyclical acceleration and deceleration and in all applications where braking resistors are normally used. The combination of the integrated AC reactor and no need for an external braking unit eliminate a large amount of additional wiring. These inverters need up to 60 % less main circuit wiring and occupy up to 40 % less space than conventional solutions, depending on the output capacity.

The FR-F740 frequency inverter drives from Mitsubishi Electric are designed for the special needs of pumps and fans. These inverters can significantly enhance the energy balance of pump and fan applications - particularly in the low-speed range and in low-load operation, where energy savings of up to 60% can be achieved. Additional savings are made possible by Mitsubishi Electric's innovative OEC (Optimum Excitation Control) technology. This system ensures that the optimum magnetic flux is always applied to the motor, thus reducing losses. The result is maximum utilisation of motor capacity at maximum efficiency.

Product range

The series covers a very broad output range from 0.1kW all the way up to 630kW. Lines include the smallest FR-D700 series for simple applications, the medium-range FR-E700 series and the high-performance FR-A700 series. The product range is complemented by the FR-F740 series that is optimised for the special requirements of pump and fan applications in the HVAC sector.

All frequency inverters feature simple operation and configuration and optimised control and data management facilities. The integrated control terminals, the one-touch digital dial and the multi-language control panel with copy function provide instantly-comprehensible information on current drive status and clear error message displays.

Networked systems are very easy to configure thanks to support for standard open network bus systems including Profibus/DP, DeviceNet, CC-Link, CANopen and LonWorks. Serial RS-422 and RS-485 interfaces and the optional USB port enable multidrop applications with up to 32 stations and connection of the latest PC and process visualisation systems.

OMRON provides high level of quality and reliability, and quick customize your inverter to match your precise requirement.
Product Lineup


JX Series - The smallest get integrated

Easy network integration
The RS-485 Modbus is built into the RS-485 port in the inverter front, making it very easy to add inverters into the network without any extra option boards. Therefore, saving money and space.

Easy communications setting
Modbus commands are implemented even in low end CP1 PLC family by Modbus-RTU Easy Master functionality, making it easier than ever to integrate the inverters into the network.

Noise Measures for Peripheral Equipment
As a noise measure, a built-in radio noise filter is a standard feature on every model* that saves on costs and space compared with the standard external filter solution. *Excluding single-phase/three-phase 200-V models.

No additional devices required
Even advanced functionality such as PID control is standard with the JX inverter making it a convenient solution for applications such as pumps & fans where pressure, flow and other processes need controlling.

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.

Side-by-side Mounting Saves Space
When several Inverters are to be mounted in a control panel, side-by-side mounting makes it possible to mount them closely together, thus saving space.

Note: Some models have restrictions in the ambient temperature, carrier frequency, and output current.
