This manual describes the basic operation methods and precautions for Mitsubishi frequency converter FR-F500J series. Including installation method, wiring and terminal specifications, operation/control, frequency setting meter and display meter adjustment, function list, alarm and protection function, specification, appearance dimension drawing and so on.
This manual covers safe handling and installation of the Mitsubishi Electric FR‑F500J (and FR‑F540J) frequency converters. It explains the required precautions such as installing on non‑flammable surfaces, avoiding contact with live terminals, and ensuring proper grounding before operation.
The document also details wiring of control circuits, RS‑485 communication setup, parameter configuration (frequency range, motor current, etc.), and motor overload protection. Emergency‑stop procedures and maintenance tips are included to help technicians keep the inverter operating reliably. This manual is written in Japanese.
