The Mitsubishi Electric FR-E840-0040-E-N6 belongs to the FR-E800 family of compact inverters for industrial motor control. Its 400 V-class design supports three-phase 380–480 V AC input, while the dual LD/ND rating allows the inverter to be selected according to the required load characteristics. Mitsubishi lists the 0040 frame rating as 0.4 kW under ND operation and 1.5 kW under LD operation.
The FR-E800 provides several motor-control methods, including V/F, advanced magnetic flux vector, real sensorless vector and PM sensorless vector control. It also includes built-in PLC functionality, digital and analog I/O, RS-485 communication, USB connectivity and STO safety functionality. These features make the FR-E840 suitable for machine automation, conveyors, pumps, fans, material handling equipment and other industrial motor-control applications.
For replacement and sourcing applications, the complete model number should be checked carefully because Mitsubishi offers multiple FR-E840 variants with different suffixes and features. The FR-E840-0040-E-N6 should therefore be matched against the existing drive nameplate and application requirements before replacement.
