As an authorised Mitsubishi Electric distributor, we continue to support customers with the FR-D800 series, the proven next-generation compact inverter that has successfully taken over from the long-standing FR-D700.
Since its introduction, the FR-D800 has established itself as a reliable and forward-thinking evolution of the D700 platform. It retains the compact footprint, simplicity and dependability that made the D700 so widely specified, while delivering meaningful improvements in performance, energy efficiency and ease of use.
Compact by Design, Powerful by Nature
The FR-D800 maintains one of the smallest footprints in its class, helping machine builders and panel designers reduce enclosure sizes and maximise valuable cabinet space. Side-by-side installation capability further supports compact panel layouts, while practical design improvements, such as the flip type front cover and integrated wiring cover, streamline installation and reduce assembly time.
Wiring is faster and more secure thanks to spring clamp control terminals, and parameter setting has been simplified with a USB Type-C connection that allows configuration directly from a PC, even without main circuit power applied. These refinements make commissioning quicker and more straightforward for engineers both in the workshop and on site.
Performance to Match Modern Applications
The FR-D800 has been engineered to support a wide range of motor types and applications. In addition to standard induction motors, it supports PM motors, including high efficiency IE5 models, helping users achieve greater energy performance. Advanced magnetic flux vector control and PM sensorless vector control enables stable, precise operation, even in demanding low-speed or high-torque environments.
With output frequencies up to 590 Hz under V/F control and enhanced regenerative braking capabilities, the FR-D800 is well suited to conveyors, lifting systems, pumps, fans, HVAC equipment and high-speed machinery. Built-in brake transistor models further improve deceleration performance while reducing the need for additional components.
Reliable EMC Compliance with Dedicated Filter Solutions
Electromagnetic compatibility is a critical consideration in modern machinery design, particularly where sensitive control equipment, communication networks or export requirements are involved.
To support compliant and trouble-free installations, Mitsubishi Electric offers dedicated EMC filter solutions designed specifically for use with the FR-D800 series. These filters help suppress conducted noise and reduce electromagnetic interference, supporting conformity with European EMC directives and international standards.
The availability of matched filter options simplifies panel design and specification, ensuring predictable performance and helping machine builders avoid costly redesign or site issues during commissioning. With clearly defined installation guidelines covering wiring layout, earthing and cable routing, achieving compliance is both straightforward and reliable.
For OEMs exporting machinery globally, the combination of FR-D800 performance and approved EMC filter solutions provides additional confidence that systems will meet regulatory requirements across different markets.
Designed for Energy Efficiency and Decarbonisation
Energy efficiency is a central focus of the FR-D800 series. The inverter supports high efficiency motor operation and includes built in energy monitoring functions, allowing users to measure power consumption and CO₂ emission reduction. This makes it easier to quantify savings and support sustainability targets.
The introduction of double rating functionality (ND and SLD) allows more precise inverter selection based on load type. For variable torque applications such as fans and pumps, users can optimise sizing, reducing both initial system cost and ongoing energy consumption.
Advanced optimum excitation control further enhances efficiency by improving motor performance during constant speed operation, helping manufacturers reduce running costs without sacrificing productivity.
Built for Safety and Global Compliance
The FR-D800 supports functional safety through its integrated Safe Torque Off (STO) function and complies with key international safety standards, including SIL2 and PLd/Cat.3. This allows machine builders to meet regulatory requirements more efficiently while simplifying overall system design.
With global certifications and compliance with major standards, the FR-D800 is ready for use in export driven OEM applications and international installations.
Smarter Maintenance, Reduced Downtime
Maintenance has also been enhanced with built in diagnostic and monitoring tools. The inverter can monitor the condition of key internal components, including capacitors and cooling systems, supporting predictive maintenance strategies. Load characteristic measurement functions help detect abnormal mechanical conditions, such as clogged filters or belt wear, before they lead to system failure.
Advanced trace functionality captures operating data immediately prior to a fault, simplifying troubleshooting and reducing downtime. For applications where continuity of operation is critical, features such as automatic restart after instantaneous power failure and emergency drive mode provide additional resilience.
Importantly, for existing FR-D700 users, parameter conversion tools within FR Configurator2 help streamline upgrades, making the transition to the FR-D800 straightforward.
A Natural Evolution of a Proven Platform
The FR-D800 is more than just a replacement for the FR-D700, it represents a considered evolution. It combines compact design, enhanced performance, improved energy efficiency, integrated EMC compliance options and smarter maintenance capabilities into a single, versatile drive platform.
As an authorised Mitsubishi Electric distributor, we are here to support you with specification advice, upgrade planning, EMC compliance guidance, energy efficiency optimisation and technical assistance. Whether you are designing new machinery or planning a retrofit, the FR-D800 offers a future-ready solution built on a proven foundation.
