The FR-D800 is the compact general purpose inverter in the Mitsubishi Electric FR series. It keeps the small body of the FR-D700 it replaces and adds PM motor control, a super light duty rating for fans and pumps, USB-C set-up, life diagnosis and Ethernet models, for conveyors, fans, pumps and general machinery up to 15kW.
Mitsubishi Electric describes the FR-D800 as a next-generation compact inverter that inherits and enhances the functions of the FR-D700. Mitsubishi Electric Europe announced the end of life of the FR-D700 in January 2026, with production ending in January 2027 and repair support continuing until January 2034, and names the FR-D800 as its replacement. Each FR-D700 family has a direct FR-D800 equivalent, outline dimensions are compatible for most ratings, and FR Configurator2 converts FR-D700 parameter settings to the new series.
The range covers 0.1kW to 15kW on three-phase 200V and 400V supplies, and 0.1kW to 2.2kW on single-phase 200V. Each drive switches between V/F, advanced magnetic flux vector and PM sensorless vector control, so one model runs standard induction motors or permanent magnet motors, including other manufacturers’ motors through offline auto-tuning. Two duty ratings are selectable by parameter: normal duty (150% for 60 seconds) for general machinery, and super light duty (110% for 60 seconds), which on fan and pump loads lets you use an inverter one size smaller than the motor.
Standard models communicate over RS-485 with Modbus RTU. Ethernet models add CC-Link IE TSN, CC-Link IE Field Network Basic and Modbus/TCP, with EtherNet/IP or PROFINET depending on the version. Safe torque off is built in, and life diagnosis now extends to the fault contact relay and main circuit elements. For more protocols, sensorless vector control or a built-in PLC function, step up to the FR-E800 Series.

The FR-D800. Mitsubishi Electric gives a direct replacement for each family: FR-D710W to FR-D810W, FR-D720S to FR-D820S, FR-D720 to FR-D820 and FR-D740 to FR-D840. The exact model depends on the rating and whether you need a communication version, so check the part number on the rating plate.
Mitsubishi Electric Europe announced the end of life of the FR-D700 in January 2026. Production ends in January 2027 and repair support continues until January 2034. Drives already installed do not need replacing because the series has been discontinued, but it makes sense to identify the FR-D800 equivalent for spares.
In most cases. Mitsubishi Electric states the outline dimensions are compatible, but some ratings differ and use a mounting attachment, for example on 400V models from 0.4kW to 1.5kW and at 11kW and 15kW. EMC filters are different, and the FM output terminal is replaced by a 0-10V AM output, so check the wiring and filtering as well as the footprint.
Yes. FR Configurator2 converts FR-D700 parameter settings to the FR-D800. Some parameters have been renumbered or removed, so review the converted settings before running the drive.
0.1kW to 15kW on three-phase 200V, 0.4kW to 15kW on three-phase 400V and 0.1kW to 2.2kW on single-phase 200V. On fan and pump loads, the super light duty rating lets you use an inverter one size smaller than the motor.
Ethernet models do. They support CC-Link IE TSN, CC-Link IE Field Network Basic and Modbus/TCP, plus EtherNet/IP on -EPA models or PROFINET on -EPB models. Standard models have RS-485 with Modbus RTU.
Yes. PM sensorless vector control is new to the series, so the same inverter can run an induction motor or a PM motor, including other manufacturers’ motors after offline auto-tuning.
Both are compact inverters. The FR-D800 covers straightforward speed control up to 15kW. The FR-E800 goes up to 22kW and adds real sensorless vector control, a built-in PLC function, more Ethernet protocols and higher safety levels on its safety communication models.
