Mitsubishi Electric MR-J3-10A MELSERVO-J3 AC Servo Amplifier

Description

Engineered for high-performance motion control, the MR-J3-10A AC servo amplifier belongs to the widely deployed Mitsubishi Electric MELSERVO-J3 series. This unit features a general-purpose interface supporting analog speed/torque control or pulse-train positioning commands, making it highly versatile for various automation architectures. It integrates seamlessly with compatible rotary and linear servo motors, delivering high-speed frequency response up to 2100 Hz to minimize settling times in high-speed applications.

The unit supports high-resolution 18-bit encoders (262,144 pulses/rev) to achieve exceptional speed stability and positioning accuracy. It features advanced vibration suppression and adaptive real-time auto-tuning, which automatically optimizes control loop parameters during operation to match shifting mechanical loads. Minimum wiring overhead is achieved through plug-and-play configuration and automatic motor recognition capabilities.

Features

• High-Speed Response: 2100 Hz speed frequency response for dynamic positioning profiles.
• High Resolution Feedback: Supports 18-bit absolute/incremental encoders for maximum speed constancy.
• Resonance Control: Advanced Vibration Suppression Control II mitigates mechanical resonance in complex structures.
• Auto-Tuning: Continuous real-time auto-tuning adjusts automatically to changing load inertias.
• Compact Profile: Highly integrated physical footprint reduces control cabinet space requirements.

Applications

• Semiconductor manufacturing machinery
• High-speed packaging and labeling lines
• Multi-axis pick-and-place robotic systems
• Precision machine tool axes and XY tables

Installation Guidelines

• Mounting: Mount vertically inside a control panel using the designated mounting holes. Maintain at least 40 mm clearances at the top and bottom, and 10 mm clearances on the left and right sides.
• Ventilation: Ensure the ambient air temperature within the cabinet does not exceed 55 degC. Install cooling fans if mounting multiple amplifiers side-by-side.
• Grounding: Always ground the amplifier PE terminal to the protective earth panel grid to minimize electro-magnetic interference (EMI).

Compliance and Certifications

• CE Marked (EMC Directive & Low Voltage Directive)
• UL Listed
• cUL Listed
