MR-J3-500T MITSUBISHI MELSERVO-J3 Series AC Servo Drive: Precision Motion Control for Industrial Automation

The MR-J3-500T is a high-performance AC servo drive from Mitsubishi Electric’s MELSERVO-J3 Series, designed for demanding industrial automation applications requiring precision, speed, and reliability. As part of the J3 Series, this model integrates advanced motion control technologies, including a built-in positioning function and CC-Link network communication, making it ideal for high-frequency positioning, rapid acceleration/deceleration, and dynamic response tasks. Though discontinued, the MR-J3-500T remains a trusted solution in sectors such as food processing, printing, packaging machinery, and robotics, where consistent performance and durability are critical.

Advanced Features

High-Speed Networking

The MR-J3-500T supports SSCNET III, a high-speed serial communication bus (50 Mbps), extending communication distances up to 800 meters (vs. 30 meters in previous generations). This enables distributed control architectures and reduces wiring complexity.

Model Adaptive Control & Real-Time Tuning

Equipped with advanced auto-tuning algorithms, the drive automatically adjusts control parameters (e.g., inertia ratio, vibration suppression) to optimize performance for varying loads. This minimizes setup time and ensures stability across diverse applications.

Compact & Modular Design

Compared to the MR-J2 Series, the MR-J3-500T reduces volume by 60% for the drive unit and 20% for servo motors, enabling space-saving installations. It also supports power-drive separation for high-power applications (e.g., 37 kW+ systems), improving scalability.

Safety & Reliability

• Magnetic Contactors: Prevents fire risks by isolating power during faults.
• Thermal Protection: Monitors internal temperatures to avoid overheating.
• Compliance: Meets global safety standards (e.g., CE, UL).

Installation & Safety Guidelines

• Power Off Before Wiring: Always disconnect power to prevent electric shock.
• Voltage/Polarity Check: Ensure correct three-phase AC 200V supply.
• Thermal Management: Avoid covering the drive; maintain ventilation.
• Handling: Use dry hands and avoid touching hot components during operation.

Conclusion

The MR-J3-500T represents a pinnacle of Mitsubishi Electric’s servo technology, combining compactness, speed, and networkability. While newer series (e.g., J4) offer enhanced features, the J3-500T remains a cost-effective choice for legacy systems or applications where its proven reliability outweighs the need for cutting-edge upgrades. For modern projects, Mitsubishi recommends evaluating the MELSERVO-J4 Series, which extends power ranges up to 30 kW and integrates USB/Ethernet debugging tools.
