The Mitsubishi FR-E720EX-0.4K is a micro-class variable frequency drive from the FREQROL E700 EX series, designed for space-constrained small motor control applications. It operates with 200-240VAC 3-phase input, delivering 0.4kW (0.5HP) rated power with 3A rated current. The EX designation indicates the micro/compact variant of the E700 series, offering the same core functionality in an ultra-compact form factor. Output frequency ranges from 0.2 to 400Hz with selectable V/F and vector control modes. Built-in Modbus RTU communication via RS-485 enables digital network integration. With IP20 protection, it is designed for DIN-rail or panel mounting. Typical applications include small conveyors, packaging machines, labeling equipment, small mixers, laboratory automation, and compact machinery where footprint and cost-efficiency are critical design considerations.
**Q: What is the difference between FR-E720EX and standard FR-E720?**
A: The "EX" suffix designates the micro/compact variant of the E700 series. It offers the same core VFD functionality (0.2-400Hz output, vector control, Modbus RTU) in a more compact physical footprint, optimized for space-constrained panel installations.
**Q: Can the FR-E720EX-0.4K run on single-phase power?**
A: No, this model requires 3-phase 200-240VAC input. For single-phase applications within the micro series, use the FR-E720S series which accepts single-phase input.
**Q: Is Modbus RTU communication included as standard?**
A: Yes, the FR-E720EX includes built-in RS-485 Modbus RTU as standard, enabling direct parameter reading/writing and command control from PLCs or HMIs without additional hardware.
**Q: What motors are compatible with this drive?**
A: The drive is compatible with standard 3-phase induction motors rated 0.2kW to 0.4kW. Use an appropriately sized motor overload protection device in accordance with local electrical codes.
**Q: Is this drive being phased out?**
A: The E700 EX series is a mature product. The current successor is the FR-E800 series which offers enhanced connectivity (built-in Ethernet) and expanded motor control capabilities while maintaining a similar compact footprint.
