MELSERVO Servo Motors – J5 Mitsubishi Electric Mexico for industrial machines and production lines

Today we'll talk about electromechanics applied to Mexico's industrial sector. In recent weeks, we've had many inquiries about selección y el control de los servomotores Mitsubishi Electric MELSERVO – J5.

The Mitsubishi Electric Servo Amplifiers They are a type of motor found in many industrial applications, and although this type of motor requires a closed-loop feedback, an integrated encoder, and a control algorithm, the position and speed control they provide makes them highly adaptable in a wide range of applications in machines and production lines.

La cuestión de cómo accionar un servomotor requiere observar cómo se implementa la detección y el tipo de servomotor que se acciona. Veamos en esté artículo los componentes que necesitará para impulsar y controlar los servomotores MELSERVO – J5 Mitsubishi Electric, así como algunas opciones de componentes para su próximo sistema electromecánico.

 

Basic aspects of how to control a servomotor

Before you start controlling a servo motor, especially those who are new to working with servo motors They should know that a servomotor is not a specific type of motor. Rather, the term «servo» means slave and refers to how a motor is driven and its position, speed, and acceleration are controlled. In a servo motor, control is applied through a feedback loop between the motor and the controller, and the motor's position/speed is detected with encoders integrated into the motor. Some sensors that provide this function are through the integration of potentiometers, Hall effect sensors for position determination, or LED sensors with a photogate and photodiode.

The servomotor is composed of three parts:

• The servo motor.
• The servo amplifier.
• The control system.

Servomotor control involves two critical elements as part of the driving and control circuit:

• Actuation signalPWM (Pulse Width Modulation) signaling is one of the most commonly used systems for controlling servomotors. This system involves generating a square wave where the duration of the high pulse is varied, while keeping the period the same (usually), with the aim of modifying the servo's position as desired. It is used in servomotors to force the rotor to turn to a specific position. By adjusting the duty cycle, the rotation rate can be adjusted.

  Servomotors are driven by sending a PWM signal through the control wire while powering the motor. Depending on the pulse width, the rotor of the servomotor can rotate a certain angle, meaning the duty cycle determines the shaft's final position. Servomotors can be powered by DC or AC voltage, and the encoder signal (if present) closes the feedback loop with the processor or controller.

• Detection and control circuitThe control and detection circuit determines the position and speed of the rotor as the motor operates. High-precision speed can be maintained through feedback control.

 

MELSERVO – J5 de Mitsubishi Electric ha llegado para mejorar el rendimiento

Setting a new standard of performance, the MELSERVO-J5 series Mitsubishi offers cutting-edge technology, with high performance for the Mexican industry with new advanced servo features, enabling users to unlock the untapped potential in their machines and production lines. The predictive maintenance capabilities of the MELSERVO-J5 series are based on the servo itself and are integrated into the base model to achieve new functions.

This servo motor is the improved version of its predecessors, the J4, J3, and J2. We can see its capabilities regarding its safety function and its power supply (100, 200, or 400 V).

The MELSERVO-J5 series products are among the first servo products on the market to support the high-speed industrial Ethernet CC-Link IE TSN, providing advanced communication benefits and easier IoT adoption.

This servomotor can now communicate with other brands and even with other networks such as EtherCAT, which is an Ethernet for control automation technology that brings the power and flexibility of Ethernet to the world of industrial automation, motion control, real-time control systems, and data acquisition systems.

In addition to pulse communication, one of the distinctive features of this servo motor that is worth highlighting and makes it much more interesting is that it works with the CC-Link IE TSN Field network. This is an ultra-high-speed, high-capacity network that provides deterministic (cyclic) synchronous communication and asynchronous on-demand (transient) information communication. Input and output control, motion control, and safety functions can be seamlessly combined.

This network has a transmission capacity of one Gigabit and the real-time protocol allow for easy and reliable data communication, as well as remote I/O communication regardless of transmission delay. Additionally, it allows for high-speed communication for management and tracking of information on devices, as well as the transmission of control data.

Los servomotores están equipados con codificadores de alta resolución (67 108 864 pulsos/revolución) para garantizar un posicionamiento estable y una fluctuación de par reducida. El MELSERVO – J5 de Mitsubishi es compatible con otros motores y amplificadores de marcas diferentes.

Características del MELSERVO – J5 de Mitsubishi

• High performanceThe MELSERVO-J5 series performance is improved across the board with a speed frequency response rate of 3.5 kHz, 256 synchronized axes with the MELSERVO-J5 motion module, and a communication cycle time of 32.5 µs, to enhance machine performance. Capabilities range from 22 kW to 55 kW.
• Quick tuning. The MELSERVO-J5 Series, through the amplifier, self-tunes in approximately 0.3 seconds. The machine can operate instantly and smoothly once the servo is enabled. No tuning experience is required because gain values are generated automatically.
• Advanced vibration suppression control. The MELSERVO-J5 series can effectively suppress vibration at both the load and machine base at frequencies as low as 100 Hz.
• CC-Link IE TSN Compatibility. In addition to supporting common industrial networks like EtherCAT, the MELSERVO-J5 series is compatible with CC-Link IE TSN, a high-speed 1 Gbps network that enables synchronization across all connected devices.
• Predictive Maintenance Based on the Servo Itself. The MELSERVO-J5 series provides predictive maintenance driven by Mitsubishi Electric's Maisart AI technology, allowing it to detect the deterioration of mechanical components. This technology exists within the servo and does not require any external control.
• Single cable with new snap-lock connector. The encoder, power, and electromagnetic brake cables are combined into a single cable for MELSERVO-J5 series motors, reducing assembly time. The one-touch locking connector eliminates the need for screw tightening, making wiring easier.
• 26-bit battery-less absolute encoder. This standard feature can achieve around 64 million pulses per revolution, allowing for precision positioning without the need to replace batteries.
