Description

Precise motion control in automated manufacturing systems is driven by the MR-J4-20A, a high-performance 1-axis servo amplifier engineered by Mitsubishi Electric. Operating within the 200V class, this unit delivers a rated output of 0.2 kW, rendering it suitable for high-speed, high-accuracy industrial positioning. Built-in features include a sinusoidal wave PWM control system and an integrated dynamic brake, ensuring immediate, controlled deceleration and reliable performance under varying dynamic loads.

The MR-J4-20A utilizes a general-purpose command interface supporting pulse-train and analog inputs for position, speed, and torque control modes. Compatibility with 22-bit high-resolution encoders allows for fine positioning feedback. Integrated safety functions, certified to international functional safety standards, provide safe torque off (STO) capabilities, reducing external circuitry requirements in safety-critical automated layouts.

Features

  • General-purpose interface for pulse train and analog command inputs.
  • Built-in Safe Torque Off (STO) function complying with EN ISO 13849-1 Category 3 PL e and IEC 61508 SIL 3.
  • Support for high-resolution 22-bit encoders (4,194,304 pulses/rev) to achieve smooth and stable low-speed performance.
  • Integrated regenerative resistor with a 10 W capacity, expandable via external units.
  • Advanced control functions including auto-tuning, adaptive vibration suppression filters, and machine analyzers.
  • Dual communication interfaces featuring standard USB for configuration via MR Configurator2 and RS-422/RS-485 for multi-axis networking up to 32 axes.

Applications

  • Packaging machines and labeling systems requiring synchronized axis control.
  • Material handling systems, conveyors, and pick-and-place gantry units.
  • Semiconductor fabrication systems and electronic component assembly.
  • Machine tool feed axes and auxiliary mechanical actuators.

Installation Guidelines

  • Mount the servo amplifier vertically on a flat, non-flammable surface to facilitate efficient natural heat dissipation.
  • Ensure clearance of at least 10 mm on the left and right sides, and at least 40 mm above and below the amplifier for ventilation.
  • Use shielded cables for encoder and control signal wiring to prevent electromagnetic interference (EMI).
  • Connect the protective earth (PE) terminal securely to the control cabinet's main grounding point.
  • Provide external circuit breakers or fuses matching the technical input ratings specified on the device.

Compliance and Certifications

  • CE (LVD, EMC Directives)
  • UL Listed / cUL
  • Functional Safety: EN ISO 13849-1 Category 3 PL e, IEC 61508 SIL 3, EN 62061 SIL CL 3, EN 61800-5-2
