MELSERVO-J3 is Mitsubishi Electric's new generation of servos with high speed, high precision, compact and flexible features. The maximum speed reaches 6000r/min, the positioning time is shorter; the high-resolution encoder 262144p/rev (18-bit) is used as a standard part to achieve stability at low speeds; the gear torque is reduced to reduce the motor torque fluctuation; the absolute encoder is standard, and there is no need to re-originate; the installation area is 40% smaller than the existing model, the structure is more compact; the volume is 20% smaller than the existing model, the connector is smaller, and the user's system is more compact; it meets EN, UL, cUL standards and is waterproof and dustproof.
The MELSERVO-J3 series is an advanced AC servo system that uses fiber‑optic networking for high‑speed, low‑noise communication. It complies with international standards such as EN, UL, CUL and offers IP65 (HF‑KP) or IP67 (HF‑SP) protection levels. The manual describes the system’s features, model configurations, and external devices.
Detailed motor and amplifier specifications are listed, including power ratings, torque, speed, encoder resolution, and mechanical dimensions. Installation guidelines, wiring diagrams, tuning procedures, and usage precautions are provided to help users set up, operate, and maintain the servo system safely and efficiently. This manual is written in Chinese.
