Description

Operating as a high-performance motion control component within the MELSERVO-J3 range, the MR-J3-60A4 servo amplifier provides high-resolution speed, torque, and position control for automated machinery. Engineered by Mitsubishi Electric, this unit works in conjunction with compatible AC servo motors to maintain precise positioning even during complex operational profiles. Its integrated control algorithms facilitate stable operation and suppress high-frequency mechanical vibration, making it a reliable choice for advanced industrial positioning setups.

Features

Natural-cooling structural design ensures silent operation and eliminates mechanical failures associated with cooling fans.
Built-in dynamic brake provides immediate motor deceleration during emergency stops or power interruptions.
Wide input voltage tolerance accommodates standard global industrial voltage grids with fluctuating electrical supplies.
Separate control circuit power supply inputs enable diagnostic operations and parameter tuning while the main power circuit is offline.

Applications

Packaging, cartoning, and high-speed labeling machinery.
Multi-axis material handling systems and automated storage/retrieval gantry configurations.
Semiconductor fabrication systems requiring precise vibration suppression.
Metal forming, cutting, and CNC tooling machines.

Installation Guidelines

Mounting Orientation: Install the amplifier vertically on a flat, solid metal panel to optimize natural heat dissipation.
Clearance Requirements: Maintain a minimum clearance of 40 mm above and below the module, and at least 10 mm on either side for adequate airflow.
Grounding: Ensure the protective earth terminal (PE) is securely grounded to prevent electromagnetic interference and maintain electrical safety.
Wiring Isolation: Route the main AC power lines and motor outputs separately from low-voltage signal/encoder cables to avoid cross-talk.

FAQ

What is the primary cooling method of the MR-J3-60A4?

The MR-J3-60A4 servo amplifier features a natural-cooling structure, which relies on convection airflow and does not require cooling fans.

What is the permissible input voltage range for the main circuit?

The main circuit is rated for 3-phase 380 to 480 VAC at 50/60 Hz, with an allowable voltage fluctuation tolerance from 3-phase 323 VAC to 528 VAC.

Does this servo amplifier include a dynamic brake?

Yes, the MR-J3-60A4 is equipped with an integrated, built-in dynamic brake for rapid emergency stopping functionality.

Can the control circuit operate independently of the main power circuit?

Yes, the control circuit uses an independent 1-phase 380 to 480 VAC supply (0.1 A), allowing diagnostics and parameter configuration while the main motor power is disconnected.
