The MD320/MD320N series inverter is a new generation of modular high-performance inverters representing the future development direction of inverters introduced by Huichuan Technology. The series adopts a three-layer modular structure standard, including a high-performance motor control module, a general function module, and an industry-specific module. Through modular design and multi-module combination, a customized platform tailored to customer needs is created. The series of inverters have control modes such as V/F, sensorless vector control (SVC), and vector control (VC), as well as various basic functions such as PID control, multi-speed, and swing frequency. Customers can choose different function modules according to their needs to meet different performance and functional requirements.
This manual introduces the MD320/MD320N series frequency transformers, highlighting their modular three‑layer design, high‑performance motor control, and vector control technology. It includes safety notices, product specifications, and the modular structure that allows flexible configuration for various applications.
The document covers mechanical and electrical installation, wiring diagrams, parameter settings, quick‑menu operation, communication options, fault diagnosis, and warranty terms. It also provides appendices for PG card usage, I/O expansion cards, serial communication protocol, and version change records. This manual is written in Chinese.
