Mitsubishi Electric MR-J2S-200A MR-J2S Servo Amplifier

Description

Engineered for high-performance motion control, the MR-J2S-200A is a digital AC servo drive module from the Melservo J2-Super series. This unit delivers precise control of speed, position, and torque across various industrial automation systems. By utilizing a sinusoidal PWM control and current control system, the drive ensures stable current delivery and optimal torque output throughout the operating range.

The MR-J2S-200A features multiple operational modes, supporting direct analog inputs for speed and torque command configuration, alongside high-speed pulse train interfaces for precise positioning tasks. Integration with a 131072 pulse-per-revolution encoder offers high-resolution feedback, minimizing positioning errors. A built-in dynamic brake is included to guarantee rapid, controlled deceleration and safe stop performance during emergency conditions or power failure events.

Features

• Sinusoidal PWM control and current control system for smooth velocity regulation.
• Built-in dynamic brake for accelerated emergency stop capabilities.
• Comprehensive onboard protective mechanisms covering overcurrent, regenerative overvoltage, overload, and motor overheating.
• High-resolution positioning feedback support of up to 131072 pulses per revolution.
• Dual-receiver pulse input capability supporting both differential receiver and open collector formats.
• Integrated cooling fan design for reliable thermal dissipation in dense electrical enclosures.

Applications

• Multi-axis packaging and sealing machinery.
• Semiconductor fabrication equipment and wafer handling systems.
• High-speed material handling and pick-and-place gantry robots.
• Precision metalworking and CNC machine tool axes.
• Automated assembly systems and rotary indexing tables.

Installation Guidelines

For correct heat dissipation, mount the servo amplifier vertically on a flat panel using the designated mounting holes. Ensure a minimum clearance of 10 mm on both sides and 40 mm above and below the unit to allow unrestricted airflow from the internal cooling fan. Avoid installation environments subject to high humidity, conductive dust, or corrosive gases. Ground the amplifier securely to the main protective earth (PE) busbar to minimize electromagnetic interference (EMI) and prevent electrical shock hazards.
