Mitsubishi Electric MR-J3-100B MELSERVO-J3 Servo Amplifier

Description

Engineered for high-precision industrial motion control, the Mitsubishi Electric MR-J3-100B is an AC servo amplifier belonging to the high-performance MELSERVO-J3 product group. This drive utilizes the high-speed, synchronous SSCNET III fiber-optic communication network, ensuring reliable real-time synchronization between the controller and the servo motor in multi-axis motion configurations.

Capable of driving 1.0 kW capacity rotary servo motors, this unit integrates advanced electronic architecture including real-time auto-tuning and advanced vibration suppression control. It supports high-resolution 18-bit absolute/incremental encoders, delivering exceptional speed stability and positioning accuracy for sophisticated mechanical processes.

Features

• High-speed SSCNET III optical communication interface with a cycle time of 0.44 ms.
• Compatible with 18-bit absolute position encoders resolving up to 262,144 pulses per revolution.
• Advanced vibration suppression control function to minimize machine resonance during high-speed positioning operations.
• Adaptive filter II and advanced real-time auto-tuning system that dynamically adjusts control gains to match changing load inertia.
• Integrated dynamic brake function for rapid motor deceleration during emergency stops or fault conditions.
• Plug-and-play configuration with automatic servo motor identification via the connection cable.

Applications

• Packaging machinery and form-fill-seal systems.
• Multi-axis semiconductor manufacturing and wafer-handling equipment.
• CNC machine tool feed drives and precision engraving machinery.
• Automated pick-and-place gantry robots and material handling lines.

Installation Guidelines

• Mounting Orientation: Install the servo amplifier vertically on a flat panel to ensure optimal heat dissipation through the integrated cooling fan.
• Clearance Requirements: Maintain a minimum of 10 mm clearance on the left and right sides, and 40 mm clearance above and below the unit for adequate ventilation.
• Grounding: Ensure the drive is solidly grounded to the control cabinet's primary ground bus to reduce high-frequency electromagnetic interference.
• Network Cabling: Use only recommended MR-J3BUS SSCNET III fiber-optic cables, respecting the minimum bending radius of 25 mm to prevent optical signal degradation.
