FR-L740-5.5K-CHT MITSUBISHI Servo Controller

Product  Description：

Mitsubishi Electric Servo Controllers, primarily known under the MELSERVO brand (such as the MR-J5 and MR-JET series), are high-precision electronic devices used to control the position, speed, and torque of servo motors. These controllers act as the sophisticated "drive" unit that receives command signals from a master controller and executes precise mechanical movements with sub-micrometer accuracy.

Product Parameters

The performance of Mitsubishi Servo Controllers is characterized by industry-leading response speeds and resolution:

• Velocity Frequency Response: Advanced models feature a frequency response of up to 3.5 kHz, significantly reducing settling time and improving machine throughput.

• Encoder Resolution: Supports high-resolution absolute encoders, often reaching 26-bit (67,108,864 pulses per revolution) for exceptionally smooth motion.

• Power Ratings: Available in a wide range of power outputs from 50W for small precision tasks to 37kW and above for heavy-duty industrial applications.

• Communication Interface: Integrated support for CC-Link IE TSN, EtherCAT, and SSCNET III/H, enabling gigabit-level synchronization between multiple axes.

• Input Power Supply: Compatible with single-phase or three-phase 200V-240V AC, and high-voltage three-phase 400V AC variants.

• Safety Features: Built-in functional safety functions such as STO (Safe Torque Off), SS1 (Safe Stop 1), and SLS (Safely-Limited Speed) compliant with international standards.

Product Advantages

Mitsubishi Servo Controllers offer several competitive advantages that enhance machine performance and longevity:

• Advanced Vibration Suppression: Features "Adaptive Filter II" and "Tuningless" functions that automatically detect and suppress mechanical resonance and load vibrations without manual adjustment.

• Predictive Maintenance: Equipped with AI-driven sensing technology that monitors the health of mechanical components like ball screws and belts, alerting users to potential failures before they occur.

• One-Touch Tuning: The auto-tuning function allows even non-experts to optimize the gain parameters of the servo system by clicking a single button in the setup software.

• Compact Footprint: Innovative circuit design and high-efficiency power modules allow for side-by-side mounting, which drastically reduces the space required in control cabinets.

• Energy Recovery: Supports common DC bus configurations that allow energy generated during motor deceleration to be shared with other axes or returned to the power line.

Product Applications

These controllers are the preferred choice for high-speed, high-precision motion control across various fields:

• Semiconductor Manufacturing: Used in wafer handling robots and wire bonding machines where nanometer-level precision is non-negotiable.

• Lithium-ion Battery Production: Governing the high-speed winding and coating processes required for manufacturing modern EV batteries.

• Printing and Converting: Synchronizing multiple rollers to maintain precise tension control in high-speed printing presses and paper converting lines.

• Packaging Machinery: Controlling "Form-Fill-Seal" machines where rapid, synchronized motion is required for high-volume output.

• CNC and Laser Cutting: Driving the X, Y, and Z axes of machine tools to ensure smooth curves and accurate dimensions in metal fabrication.

Important Precautions

To ensure safe operation and prevent damage to the drive or motor, the following precautions are mandatory:

• Correct Motor Matching: Always ensure the servo controller model matches the specific motor series and capacity. Using a mismatched motor can lead to uncontrollable movement or fire.

• Regeneration Management: For applications involving high-inertia loads or frequent deceleration, ensure an external regenerative resistor is properly sized and connected to prevent overvoltage errors.

• Electromagnetic Interference: Servo drives generate high-frequency noise. Use shielded cables for encoder and power lines, and ensure the controller is grounded to a single point to prevent signal interference.

• Proper Cooling: The controller generates significant heat during high-duty cycles. Maintain the specified clearance between units and ensure the cooling fans are not obstructed by dust or debris.

• Wiring Safety: Wait at least 15 to 20 minutes after turning off the power before touching terminals. High-voltage capacitors inside the controller remain charged for a significant period.
