This manual describes the expansion of functions such as remote operation of the operation panel and RS485 communication by using the RJ-45 connector (combination socket) for the operation panel of the inverter main body and the RS485 communication card (optional).
The document provides detailed instructions for using the RS485 communication option of the FRENIC‑Mini and FRENiC‑VP series. It covers safety precautions, connection methods, protocol options, and function code usage.
It also includes specifications of the RJ‑45 connector, cable requirements, supported protocols (Modbus RTU and Fuji general inverter protocol), and wiring diagrams for proper installation and troubleshooting. This manual is written in Chinese.
