Fuji Electric FRN0431G2W-4GU

Built for Industry 4.0 environments where connectivity, safety certification, and precision are non-negotiable, the Fuji Electric FRN0431G2W-4GU is a FRENIC-MEGA (G2) series advanced variable frequency drive (VFD) for 460V three-phase applications, rated at 350 HP / 415A (Normal Duty), 250 HP / 325A (Heavy Duty).

The FRENIC-MEGA G2 generation introduces key advancements over the G1 platform: native support for permanent magnet (PM) motors — both Interior PM (IPM) and Surface PM (SPM) — enabling pairing with high-efficiency PM motors for system efficiency well above standard induction motor installations. Built-in Safe Torque Off (STO, SIL2/PLd certified) eliminates external safety contactors in many machine safety architectures, meeting IEC 62061 and ISO 13849 requirements.

High-response vector control provides fast torque response with or without encoder feedback. Communication: RS-485 Modbus RTU standard; optional PROFIBUS-DP, DeviceNet, EtherNet/IP, CC-Link, and PROFINET for Industry 4.0 integration. Additional features: enhanced EMC, extended operating temperature range, improved cooling, and comprehensive diagnostics.

The FRN0431G2W-4GU is well-suited for precision process control and tension winding, permanent magnet motor applications for improved efficiency, and safety-critical machinery requiring certified Safe Torque Off (STO). UL/cUL listed and CE marked.
