Description

Engineered for high-performance motion control, the MR-J2S-700A functions as a versatile AC servo drive within the Mitsubishi Electric MELSERVO-J2-Super product line. This amplifier utilizes a specialized sinusoidal PWM control and current control system to deliver high-precision torque, speed, and positioning capabilities. Designed to interface seamlessly with compatible rotary servo motors, this unit features a built-in dynamic brake and an integrated fan-cooling system to maintain thermal stability during high-duty cycles. The device supports position, speed, and torque control modes, offering robust flexibility for sophisticated industrial automation architectures.

Features

  • Advanced sinusoidal PWM control/current control system for smooth and precise motor operation.
  • Built-in dynamic braking mechanism for rapid motor deceleration and enhanced system safety.
  • Dual positioning feedback integration supporting high-resolution encoders up to 131,072 pulses per revolution.
  • Comprehensive protective architecture including overcurrent shutdown, regeneration overvoltage, overload detection, and encoder fault protection.
  • Integrated fan-cooling design maintaining reliable performance in open-frame IP00 installations.

Applications

  • Multi-axis CNC machine tools and precision metalworking machinery.
  • High-speed packaging, labeling, and filling equipment.
  • Semiconductor fabrication systems and robotic pick-and-place units.
  • Material handling systems and automated warehousing line controls.

Installation Guidelines

  • Mount the unit vertically on a rigid, vibration-free backplane to ensure optimum chimney-effect airflow.
  • Observe standard clearance requirements of at least 10 mm on the sides and 80 mm at the top and bottom of the amplifier.
  • Verify input line voltages are within the permissible 170-253 VAC range before applying power.
  • Route low-voltage control signals (CN1/CN2 cables) separately from high-voltage motor output and AC power cables to prevent electromagnetic interference.
  • Ensure proper system grounding by connecting the ground terminal of the amplifier to the primary protective earth (PE) system.
