Description

Engineered for high-precision motion control applications, the MR-J3-200B is a high-performance, 2.0 kW AC servo amplifier belonging to the Mitsubishi Electric MELSERVO-J3 series. This unit operates via the high-speed SSCNET III (Servo System Controller Network) fiber-optic communication interface, enabling synchronous multi-axis control with minimal wiring and superior noise immunity. By transmitting data at high speeds, this amplifier ensures ultra-short positioning times and reliable communication between the controller and the drive.

The unit features advanced vibration suppression capabilities, which dynamically adjust to machine resonance and minimize mechanical stress during operation. Equipped with auto-tuning functions, the drive facilitates rapid installation and setup by automatically optimizing control loop parameters. It seamlessly interfaces with high-resolution 18-bit absolute/incremental encoders to provide outstanding velocity stability and positioning accuracy across diverse industrial automation environments.

Installation Guidelines

• Mounting Direction: Mount the amplifier vertically on a flat panel to ensure optimal heat dissipation.
• Clearances: Maintain at least 10 mm of clearance on the left and right sides, and 40 mm above and below the unit.
• Cooling: Install in an enclosure free of conductive dust, corrosive gases, and oil mist. Ensure cooling fans are unobstructed if installed within a sealed cabinet.
• Grounding: Ensure the PE terminal is securely connected to a Class D ground (grounding resistance of 100 ohms or less) to prevent electrical shock and reduce EMI.

Compliance and Certifications

• CE Mark (EMC Directive & Low Voltage Directive)
• UL Listed
• cUL Certified
