Time to Move On: Why the Mitsubishi FR-D800 is the Smarter Choice For FR-D700 Users
The Mitsubishi FR-D700 has been a solid workhorse for years. Reliable, compact, and easy to use, it earned its place in thousands of UK factories. But times change, and using the latest advances in technology, Mitsubishi Electric has raised the bar with the new FR-D800 series.
We know any change takes effort. So, why should you make the switch to the FR-D800?
1. Quicker Wiring and Easier Setup
Any Engineer who hates fiddly terminals will welcome the new Mitsubishi FR-D800. With spring clamp terminals, wiring is faster, cleaner, and more secure. Combined with the flip-type front cover and integrated wiring cover, and you’ll spend less time on installation and more time keeping production running.
2. Ready for Today’s Motors (and Tomorrows)
The existing FR-D700 can only handle induction motors, but the FR-D800 adds support for high-efficiency permanent magnet (PM) motors, like the latest Mitsubishi EM-A Series  . With auto-tuning built in, getting the right performance out of your motor is straightforward, whether it’s Mitsubishi or not.
3. Our Exclusive Launch Offer
At LC Automation, we know just how good the Mitsubishi FR-D800 really is, and we're here to help you make the switch. As an added benefit, every new FR-D800 inverter drive you purchase before 30th November 2025 will come with a free Mitsubishi MCB Breaker. Which breaker do I need? Don't worry, we have done the hard work for you. Each FR-D800 model on our website has the correct MCB specified at the bottom of the page, or download our offer sheet for more info.
4. Designed with Sustainability in Mind
Energy efficiency has been at the heart of Mitsubishi Electric's Inverter Drives from the start, and the ultra-compact FR-D800 is driving that legacy forward. The FR-D800 reduces standby power and works seamlessly with the latest high-efficiency motors, helping to cut your CO2 emissions as well as your energy costs.
5. Easier Maintenance and Better Reliability
Enhanced monitoring functions make it easier to spot issues before they become problems, keeping downtime to a minimum.
6. Tough Enough for Harsh Environments
An expanded ambient temperature range and coated PCBs mean the FR-D800 is able to cope with more demanding industrial conditions than the D700.
