MR-J4-40A | Mitsubishi Electric | Amplificateur de servo

Description

Engineered for high-performance motion control systems, the MR-J4-40A servo amplifier belongs to the widely specified Mitsubishi Electric MELSERVO-J4 product series. This drive module regulates the position, speed, and torque of rotary servo motors rated up to 0.4 kW. Operating on a 200V AC supply class, it integrates advanced tuning algorithms to ensure stability and minimize tracking errors in complex mechanical systems.

The MR-J4-40A features compatibility with high-resolution 22-bit absolute and incremental encoders, enabling precise positioning with up to 4,194,304 pulses per revolution. The unit accepts pulse train commands and analog signals, facilitating straightforward integration with host PLCs, dedicated motion controllers, or CNC systems. Its dual-channel analog monitoring interface simplifies diagnostic setup and real-time performance tracking during commissioning.

Features

• Compatible with high-resolution 22-bit encoders for sub-micron positioning accuracy.
• Supports multi-axis configurations via standard pulse and analog command interfaces.
• Real-time auto-tuning function dynamically adapts to varying load inertias.
• Advanced vibration suppression control systems target both low-frequency transient oscillations and high-frequency resonances.
• Dual-channel analog monitor outputs for direct oscilloscope or data logger analysis.
• Flexible input power scheme accepting both single-phase and three-phase 200V AC power.

Applications

• Packaging Machinery: Multi-axis filling, capping, and wrapping systems requiring high-speed synchronization.
• Semiconductor Manufacturing: Ultra-precise pick-and-place systems and wafer handling robotics.
• Material Handling: Automated storage and retrieval systems (ASRS) and high-speed sorting conveyors.
• Machine Tooling: Feed drive control for auxiliary axes in CNC milling and lathe centers.

Installation Guidelines

• Mounting Alignment: Always mount the amplifier vertically on a flat, rigid metal backplane to ensure convective cooling.
• Clearance Requirements: Maintain a minimum clearance of 10 mm on both sides and 40 mm above and below the amplifier chassis.
• Ambient Temperature: Ensure the local enclosure temperature remains between 0 degC and 55 degC. For environments exceeding 45 degC, provide forced-air cooling.
• Shielding and Noise Control: Use shielded twisted-pair cables for the CN1 control lines and CN2 encoder connection. Ensure the shield braid is grounded directly to the panel chassis via grounding clamps.

Compliance and Certifications

• CE Mark (Low Voltage and EMC Directives)
• UL listed / cUL certified
• KC (Korea Certification)
