Inverters – FR-S 520 SE / FR-S 540 E

An Intelligent Solution for Every Drive Task



The FR-S 500 series of frequency inverters from Mitsubishi Electric provide an easy entry to the world of modern variable-speed drive technology. These inverters are ideal for simple drive tasks with V/f control up to 3.7kW output, with a comprehensive range of intelligent functions that cover the requirements of a wealth of applications in trade and industry.

With their compact design and clear layout the FR-S 500 inverters make installation and configuration fast and simple - also on a DIN rail adapter in the switchgear cabinet if you want.

The integrated control unit with the one-touch Digital Dial facilitates efficient entry of all drive parameters. Or you can choose the alternative alphanumeric control panel with multi-language support and a copy function. Both displays provide at-a-glance information on the current status of the drive system and clear error messages.

Inverters – FR-D 700

The micro-drive solution


Simple and safe operability, compact design as well as improved performance features were the focus during the development of the new FR-D700 frequency inverter. A drive was created that set new standards in the field of compact drives.

Improved functions and device properties such as simplified cabling thanks to spring clamps, the integrated Digital Dial with LED display, improved performance yield in the low-speed range as well as the integrated emergency stop function make the FR-D700 the new standard in the ultra compact class.

The FR-D700 is especially advantageous for standard applications by virtue of its user- friendliness. It is the correct choice in both simple and more sophisticated applications. Typical applications are feeder and conveyor drives, machining tools or gate and door drives.

Failure safety with self-diagnostics

This inverter actively monitors its own functional safety. If, for example, the fan rpm decreases to 50 %, a pre-alarm is triggered. An internal measuring program monitors the ageing of the capacitors and an operating hours counter enables the operator to plan the best time for servicing. Protection and overload functions like the phase failure monitoring system for both the input and output circuits ensure trouble-free operation.

Additional energy savings

The FR-D700’s OEC function helps to further optimize current and hence power consumption of the motor. The result is an additional decrease in energy requirement compared to a conventional inverter.

Long service life

The FR-D700 is designed for a service life of over 10 years. This is made possible, among other things, by high-performance heat- resistant capacitors, cooling fans with sealed bearings and special lubricating grease. The flow of cooling air comes into contact only with the heat sinks and not electronic components. This ensures that no dust or dirt can collect on the components. The circuit boards are protected against aggressive environments with single or double layer conformal coating – another feature that ensures longer service life.

Upgraded functional scope

To protect both staff and valuable machinery, the FR-D700 has innovative functions that enable it to respond with great sensitivity to a variety of external factors.

Simple operation

  • Simple cabling
  • Easy parameterization
  • Integrated control unit
  • Simple network connection
  • Change cooling fan in only 10 seconds
  • Controlled deceleration during brief power failures
  • Automatic restart after power failures
  • Integrated emergency stop function

More standard functions

  • Sensorless vector control
  • Autotuning
  • 200% overload capacity
  • Side by side mounting
  • Integrated brake chopper
  • Password function
  • Dancer control for winders
  • Traverse function

Inverters – FR-E 700

The Compact Drive Solution



The new powerhouse

With 11 million frequency inverter drives already sold, Mitsubishi Electric now introduces its latest generation of compact inverters, the new FR-E700 series. In addition to better features and performance than their predecessors, the models in the new series are also more compact and even easier to install.

Improvements include an integrated USB port, an integrated one-touch Digital Dial control with a display, improved power usage at low speeds and an expansion slot compatible with the many option cards from the 700 series. All this makes the FR-E700 an economical and highly-versatile solution for a wide range of applications from textiles machines to door and gate drive systems to material handling systems.

Intelligent functions for every application

  • Sensorless Vector Control
  • Advanced autotuning
  • Overload capacity increased to 200% for 3 seconds
  • Brake chopper
  • Torque limiting
  • External brake handling
  • Integrated control unit
  • Powerful software
  • Integrated USB port
  • Self-diagnostics for reliable operation
  • Side by side mounting

Responsive technology

To protect both staff and valuable machinery the new FR-E700 series is packed with innovative functions that enable the inverters to respond with great sensitivity to a variety of external events.

  • Controlled deceleration for brief power failures
  • Automatic restart after power failures

An investment in the future

Long lifetime – Frequency inverter drives from Mitsubishi Electric are famous for their reliability and longevity. The FR-E700 is designed for a service life of over 10 years. Among other things, this is made possible by high-performance heat-resistant capacitors, cooling fans with sealed bearings and special lubricating greases. The flows of cooling air only come into contact with the heat sinks, not with the electronic components, ensuring that no dust or dirt can collect on the components.

The circuit boards are very well protected against aggressive environments with single or double coatings of varnish – another feature that ensures a longer service life.

Fast servicing – The fans are designed as compact units that can be replaced in less than 10 seconds for cleaning or in the event of failure. Even replacing the entire inverter is a quick and simple operation – there is no wiring work at all because the terminal block is removable.

Versatile design

Compact installation – The installation footprint is the same as that of the predecessor models but the FR-E700 units can now be installed directly next to one another. Heat dissipation has been optimised by designing the heat sinks so that they can now be installed outside the switchgear cabinet.

Flexible connection and expansion – FR-E700 inverters can be connected to RTU Modbus and network systems like Profibus/DP, CC-Link, DeviceNet and LonWorks.
