Mitsubishi Electric MR-J4-200B MELSERVO-J4 Servo Amplifier

Description

Designed for high-precision motion control applications, the MR-J4-200B functions as a high-performance rotary servo, linear servo, and direct drive motor controller within the MELSERVO-J4 platform. This unit interfaces seamlessly via the high-speed SSCNET III/H synchronous network, enabling highly synchronized multi-axis operations with minimal transmission delay.

Operating on a 200V class voltage input, this unit delivers a rated output capacity of 2000W (2.0 kW). It incorporates advanced diagnostic and machine-tuning capabilities, including real-time vibration suppression and a "tough drive" function that prevents sudden shutdowns by automatically adjusting parameters during transient overloads or temperature spikes.

Features

• High-speed SSCNET III/H communication interface for precise multi-axis synchronization and rapid control cycles.
• One-touch tuning functionality that automatically configures gain and vibration suppression for optimal mechanical load matching.
• Built-in Safe Torque Off (STO) function complying with EN ISO 13849-1 Category 3 PL e and IEC 61508 SIL 3.
• Real-time friction and vibration monitoring to support predictive mechanical maintenance schedules.
• Forced cooling mechanism combined with an IP20 protective structure for reliable performance inside control cabinets.

Applications

• Automated assembly and multi-axis robotics systems
• Packaging, wrapping, and labeling machinery
• Semiconductor and flat-panel display manufacturing equipment
• High-speed material handling and gantry positioning units
• Precision machine tool axes

Installation Guidelines

• Mounting Orientation: Install vertically on a flat, rigid panel to allow adequate convection airflow.
• Clearance Requirements: Maintain a minimum clearance of 10 mm on either side of the amplifier and at least 40 mm above and below the unit for force cooling dissipation.
• Grounding: Connect the Protective Earth (PE) terminal of the amplifier directly to the main cabinet ground busbar using a low-impedance conductor.
• Cabinet Environment: Keep the ambient operating temperature between 0 and 55 Celsius. Ensure the environment is free from conductive dust, corrosive gas, and high moisture levels.
