Variateur servo Mitsubishi Electric MR-J2-70A MR-J2

Description

Designed for highly precise industrial motion control, the MR-J2-70A is a high-performance AC servo drive belonging to the Mitsubishi Electric MELSERVO-J2 series. This module uses an advanced sinusoidal PWM control and current control architecture to provide smooth torque delivery, exceptional positioning accuracy, and responsive speed control across varied load profiles. It is built to seamlessly interface with MELSERVO-compatible AC servo motors, offering robust performance in demanding production environments.

The unit features a dual-mode power input capability, operating on either a 3-phase or single-phase AC supply. Its integrated speed and position control loops allow for fine-tuning dynamics, making it an optimal selection for complex machinery synchronization and automated assembly setups.

Features

• Sinusoidal PWM control and current control system for optimized motor operation.
• Compatible with both 3-phase 200 to 230 V AC and single-phase 230 V AC input configurations.
• High-speed response capability with a speed frequency response of 250 Hz or more.
• Wide speed regulation range utilizing external analog voltage or internal digital parameter controls.
• Robust thermal management designed for tight control cabinet integration.

Applications

• Multi-axis CNC machine tool path control.
• Automated packaging and labeling systems.
• Precision material handling and product conveyor synchronization.
• Textile machinery and high-speed printing presses.

Installation Guidelines

• Mounting: Install the drive vertically on a flat, rigid panel surface inside a dust-free and oil-mist-free control cabinet.
• Clearance: Maintain at least 10 mm of clear space on both left and right sides, and 40 mm above and below the unit to ensure adequate convective airflow.
• Grounding: Connect the protective earth (PE) terminal securely to the system ground bus to prevent static buildup and mitigate electrical noise.
• Wiring: Route high-voltage power lines and low-voltage command cables through separate conduits to prevent electromagnetic interference.
