This manual covers all aspects of the Delta VFD‑L series variable‑frequency drives, including delivery inspection, name‑plate information, storage, installation, basic wiring, communication setup, and safety precautions. It is intended for users and service technicians who need to install, configure, and maintain the drives safely and reliably.
Key sections describe the three control modes (communication, panel, external terminal), DIP‑switch configuration, parameter tables, error‑message indications, and recommended maintenance procedures. Technical specifications, mechanical dimensions, and wiring diagrams are provided to aid proper integration into motor‑control systems. This manual is written in Chinese.
