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.
