Mitsubishi Electric MR-J4W2-22B MELSERVO-J4 2-Axis Digital AC-Servo Amplifier

Description

Designed for high-performance multi-axis motion control, the MR-J4W2-22B servo amplifier enables independent, highly synchronized control of two axes within a single, space-saving housing. This MELSERVO-J4 series dual-axis digital AC-servo amplifier leverages the high-speed SSCNET III/H fiber-optic communication network, making it ideal for systems requiring fast cycle times, precise positioning, and minimized noise susceptibility. By combining two axes into a single unit, the system reduces panel space requirements, simplifies wiring layouts, and lowers overall installation costs compared to traditional single-axis configurations.

Features

• Dual-axis integration allows the control of two separate servo motors from a single physical unit, optimizing cabinet space.
• SSCNET III/H interface supports high-speed, bidirectional fiber-optic communication for real-time synchronous motion control.
• Compatible with high-resolution encoders to achieve exceptional positioning accuracy and smooth velocity profiles.
• Advanced vibration suppression control technology minimizes mechanical resonance during rapid acceleration and deceleration cycles.
• Reduced wiring footprint via shared power and bus lines across both integrated axes.

Applications

• Multi-axis packaging and labeling machinery
• High-speed pick-and-place assembly systems
• Semiconductor manufacturing and wafer handling equipment
• Material handling and cartesian coordinate robotics
• Precision machine tool auxiliary axes

Installation Guidelines

For optimal reliability and performance, install the servo amplifier vertically in an enclosed, dust-free control cabinet. Ensure a minimum clearance of 10 mm on both the left and right sides, and 40 mm above and below the unit to allow for sufficient convective air cooling. Use high-quality fiber-optic cables for the SSCNET III/H network connections, adhering strictly to the minimum bending radius specified by the cable manufacturer to prevent signal attenuation or damage. Ensure the amplifier chassis is properly grounded directly to the main cabinet ground plate.
