The Rockwell TH4108-M/A remote controller manual explains appearance, functions, wiring, and operation for controlling variable frequency drives.
This manual introduces the TH4108-M/A remote controller for variable frequency drives, describing its physical layout, key features, and the RS‑485 communication capabilities that allow remote start, stop, speed control, and direction changes. It also details the optional wireless module and the ability to connect external I/O buttons.
The document provides wiring diagrams for both M‑type and A‑type units, step‑by‑step instructions for setting parameters, and safety guidelines for cable length, grounding, and lightning protection. Users can configure communication settings, address multiple drives on a bus, and adjust operation modes such as master‑control or listening mode. This manual is written in Chinese.
