MITSUBISHI MR-J3-D05 Safety Logic Unit

Product Dimensions：

The Mitsubishi MR-J3-D05 is a specialized high-performance servo drive accessory, specifically a converter unit (or power supply unit) within the renowned MELSERVO-J3 series. It is designed to facilitate the connection of multiple servo amplifiers to a shared DC bus, optimizing energy efficiency and cabinet space.

1. Product Detailed Description

The MR-J3-D05 serves as a DC power supply unit that converts AC input into a stable DC voltage for the MR-J3 series servo amplifiers. It is typically used in multi-axis systems where multiple servo motors operate simultaneously. By using a shared DC bus, the system can redistribute regenerative energy from decelerating motors to those that are accelerating, significantly reducing overall power consumption and heat dissipation.

3. Key Advantages

• Energy Efficiency: The common DC bus allows for “energy sharing” between axes, reducing the need for external regenerative resistors and lowering electricity costs.

• Space Saving: By centralizing the power supply, you can eliminate multiple individual power cables and circuit breakers, resulting in a much cleaner and more compact control cabinet.

• High Reliability: Built with Mitsubishi’s industry-leading semiconductor technology, ensuring stable operation even in demanding industrial environments.

• Simplified Wiring: Reduces the complexity of the AC input wiring, as only the converter unit requires a high-capacity AC connection.

4. Safety & Operational Precautions

• Wait for Discharge: After turning off the power, wait at least 15-20 minutes for the charge lamp to turn off before touching terminals. The DC bus retains high voltage that can be lethal.

• Proper Grounding: Ensure the unit is grounded correctly to prevent electrical noise interference and protect personnel.

• Correct Pairing: Only use the MR-J3-D05 with specific DC-input compatible servo amplifiers. Using it with standard AC-input amplifiers may cause permanent damage.

• Ventilation: Do not block the cooling fans or vents. Maintain the specified clearance distances within the cabinet to prevent overheating.

5. Product Applications

The MR-J3-D05 is ideal for complex, multi-axis machinery where synchronized movement is required:

• Printing Machinery: Managing multiple rollers and tension control axes.

• Packaging Systems: Synchronizing conveyors, feeders, and sealers.

• Automotive Assembly: Powering robotic arms and positioning stages.

• Textile Machines: Handling high-speed weaving and spinning axes that frequently accelerate and decelerate.
