Mitsubishi Electric MR-J4-10B MELSERVO-J4 Servo Amplifier

Description

Precise closed-loop control in automated motion applications is provided by the MR-J4-10B digital AC servo amplifier. Engineered as part of the high-performance Mitsubishi MELSERVO-J4 series, this controller delivers a rated output of 0.1 kW and operates on a 200V class supply. The unit utilizes the high-speed SSCNET III/H motion network to achieve synchronous, high-resolution communication with motion controllers and system CPUs, making it ideal for multi-axis configurations requiring strict synchronization.

This amplifier integrates advanced machine tuning features, including real-time auto-tuning, adaptive vibration suppression filters, and robust control algorithms that automatically adjust to changing mechanical loads. It supports standard rotary servo motors, linear motors, and direct drive motors while executing high-accuracy full-closed loop control via dual-wire communication interfaces. Standard safety configurations feature Safe Torque Off (STO) capability to meet stringent global machinery safety directives.

Features

• High-speed SSCNET III/H communication interface supporting cycle times down to 0.222 ms.
• Integrated Safe Torque Off (STO) function certified to SIL 3 and PL e safety standards.
• Advanced vibration suppression control II and adaptive tuning filters to minimize mechanical resonance.
• Supports full-closed loop control using high-resolution external encoders.
• Dual-channel analog monitor outputs for real-time diagnostic observation and tracking.
• Built-in dynamic brake for rapid deceleration and safety shutdown protection.
• USB interface for direct connection to PC-based setup and commissioning software.

Applications

• Semiconductor and electronics assembly machinery.
• Packaging, labeling, and food processing lines.
• Multi-axis CNC machine tools and precision metalworking equipment.
• High-speed pick-and-place robotic systems.
• Textile processing and automated industrial assembly lines.

Installation Guidelines

• Mounting Orientation: Install the servo amplifier vertically on a flat, rigid back panel to ensure proper heat dissipation.
• Clearance Distances: Maintain at least 10 mm clearance on both the left and right sides of the unit, and 40 mm clearance above and below for optimal airflow.
• Grounding: Ensure a solid, low-impedance ground connection to the Protective Earth (PE) terminal. Use a dedicated ground wire to minimize electromagnetic interference (EMI).
• Enclosure Protection: For environments with high concentrations of dust, moisture, or oil mist, install the amplifier inside a sealed electrical enclosure meeting IP54 or higher standards.

Compliance and Certifications

• CE Mark (Low Voltage and EMC Directives)
• UL Listed / cUL Listed
• TUV Certified (IEC 61508 SIL 3, EN ISO 13849-1 PL e)
• KC (Korea Certification)
