Mitsubishi MR-J3-200BRJ004U519: Linear Servo Motor Amplifier

Drive high-performance linear servo motors with precision. The Mitsubishi MR-J3-200BRJ004U519 is a specialized 2-kilowatt servo amplifier. It is engineered to control linear servo motors, providing direct thrust force for applications like pick-and-place, precision assembly, and linear transport systems.

Detailed Technical Specifications

• Product Model: Mitsubishi MR-J3-200BRJ004U519 (MELSERVO J3 Series).
• Power Rating: 2000 W (2 kW) rated output, 11 A rated current.
• Motor Type: Compatible with linear servo motors (thrust force up to 300 N with liquid cooling).
• Power Supply: 200-230V AC, 200V class. Configurable for single-phase (2P) or three-phase (3P) input.
• Communication: SSCNET III/H high-speed serial communication network.
• Built-in Features: Dynamic brake and regenerative resistor.
• Operating Temperature: 0°C to +55°C.
• Cooling: Designed for use with liquid-cooled linear motor stators for optimal performance at high thrust.

Installation & System Integration

• Motor Pairing: Must be matched with a compatible Mitsubishi linear servo motor model. Verify thrust constant and motor inductance compatibility.
• Cooling System Requirement: For continuous operation at the full 300 N thrust, a liquid cooling system for the linear motor is mandatory to dissipate heat.
• Network Setup: The SSCNET III/H network uses fiber optic cables for noise-immune, high-speed communication between the drive and the motion controller.
• Power Configuration: The input phase (2P or 3P) is set via internal jumpers or parameters. Ensure correct configuration for your facility's power.
• Regenerative Load: The internal regenerative resistor is typically sufficient for linear motor applications, but verify based on move profile and load mass.

Expert FAQs

• What is the primary advantage of using a linear servo system over a rotary servo with a ball screw?
  Linear servos provide direct linear motion, eliminating backlash, mechanical wear, and efficiency loss from screws or belts. They enable higher speeds, accelerations, and precision over long travels.
• What does "thrust force 300 N (liquid-cooling)" indicate?
  This is the maximum continuous thrust force the paired linear motor can produce when its stator is actively cooled by a liquid system. Without liquid cooling, the continuous thrust rating would be significantly lower due to thermal limits.
• When would I choose single-phase vs. three-phase input?
  Use three-phase input when available, as it provides more balanced power and is generally preferred. Single-phase input is used when three-phase power is not accessible at the machine, but note it may have implications for total available power and harmonic distortion.
• How does SSCNET III/H differ from standard SSCNET III?
  SSCNET III/H offers higher transmission speeds and enhanced synchronization performance, which is critical for high-precision, multi-axis linear motion systems where precise coordination between axes is paramount.
• Is an external motion controller always required?
  Yes. This is an amplifier, not a controller. It requires a Mitsubishi motion controller (like a Q series or R series CPU with motion module) to send trajectory commands over the SSCNET III/H network.
