Harnessing the Power of Regenerative Options in MEL-SERVO MR-J2S-B Servo Systems

by Bryan Hellman July 11, 2024

In the realm of industrial automation, energy efficiency and system performance are paramount. The MEL-SERVO MR-J2S-B series servo amplifiers by Mitsubishi Electric offer advanced regenerative options that can significantly enhance both. This blog will explore the regenerative features of the MR-J2S-B series, including brake units and return converters, and how they can be leveraged to optimize your servo systems.

Introduction to Regenerative Options

Regenerative options in servo systems refer to the ability of the servo amplifier to capture and reuse energy generated during deceleration or braking. This not only improves energy efficiency but also reduces heat generation, contributing to the longevity and reliability of the system. The MEL-SERVO MR-J2S-B series includes several regenerative features designed to optimize performance and efficiency in various applications.

Understanding Regenerative Energy

During deceleration, servo motors act as generators, converting kinetic energy back into electrical energy. Without regenerative options, this energy is typically dissipated as heat through resistors, which can lead to energy loss and increased cooling requirements. Regenerative options enable this energy to be returned to the power supply or reused within the system, enhancing overall efficiency.

Key Regenerative Features of the MR-J2S-B Series

1. Regenerative Brake Units:

Function: Regenerative brake units absorb the energy generated during deceleration and convert it back into reusable electrical energy. This reduces the energy dissipated as heat and enhances system efficiency.
Benefits: By capturing and reusing regenerative energy, brake units help lower energy consumption and reduce operating costs. They also minimize the need for additional cooling, extending the life of the servo amplifier and motor.

2. Return Converters:

Function: Return converters direct the regenerative energy back into the power grid or another part of the system, rather than dissipating it as heat. This is particularly useful in systems with multiple servo amplifiers, allowing energy to be shared and reused effectively.
Benefits: Return converters enhance overall energy efficiency and reduce the environmental impact of the system. They also help in stabilizing the power supply by managing energy flow more effectively.

Implementing Regenerative Options

1. Selecting the Right Components:

Brake Units: Choose a brake unit that matches the power and energy requirements of your servo system. Ensure it is compatible with the MR-J2S-B series and can handle the expected regenerative energy levels.
Return Converters: For systems with multiple servo amplifiers, consider implementing return converters to optimize energy reuse. Ensure proper sizing and compatibility with your existing infrastructure.

2. Installation Guidelines:

Proper Placement: Install brake units and return converters close to the servo amplifiers to minimize energy loss and ensure efficient energy transfer.
Wiring and Connections: Follow the manufacturer's guidelines for wiring and connections. Use high-quality cables and connectors to ensure reliable performance and minimize energy loss.

3. Configuration and Tuning:

Parameter Settings: Use the MR Configurator software to configure the regenerative options. Adjust parameters such as deceleration rates and energy thresholds to optimize performance.
Testing and Validation: Conduct thorough testing to ensure the regenerative options are functioning correctly. Monitor system performance and make necessary adjustments to achieve the desired efficiency and reliability.
