Melservo J2 Super

The MELSERVO-J2-Super is a product line by Mitsubishi Electric. It includes servo amplifiers and motors. It is designed to provide users with standard servo functions to fulfill their servo application needs. The MELSERVO-J2-Super offers a general-purpose servo interface. It also features SSCNET serial bus compatible interface for commands. Its modules support higher precision, torque, and motor speed. Its products support built-in positioning function and program operation function. Users can experience super performance with J2-Super modules. It includes a 17-bit absolute encoder (131072p/rev). Which is used for ensuring high performance and stability even at lower speeds. The wiring and motor sizes in the J2 super series are the same as the older MELSERVO modules. In addition, using a high-performance CPU has significantly improved the response rate. The frequency response of the speed loop is also improved to 550 Hz or greater, which can further improve the machine's performance. The MR-J2-Super series is ideal for use in high-speed positioning applications. Furthermore, the absolute positioning method can connect a battery to the servo amplifier. Hence, there is no need to replace the servo motor. Users can now create a complete synchronized system using J2-Super's SSCNET interface with cycle times of up to 0.888ms between controller and amplifier. Model adaptive control, advanced real-time auto-tuning, and an MR configurator are also supported by the MELSERVO-J2-Super. It also has a machine simulation function, which allows users to confirm performance without replacing the motor. The MELSERVO-J2-Super product platform offers superior quality servo amplifiers and motors with standard functions, safety features, and reliable mechanical parts.

General Characteristics

Servo solutions from the MELSERVO J2 Super series are highly efficient. They have high performance and high functionality because of the various features incorporated in their designs.

  • These servo solutions have a 17-bit high-resolution encoder, which gives 131,072 pulses per revolution. This makes the system stable even at low speeds.
  • Generally, servo motors from these servo systems are equipped with an incremental encoder which requires a specific rotor point to be available at the home position. However, the user also has the choice to install an absolute encoder on the rotor shaft, which will eliminate the need for the rotor to return to the home position. This can be done by simply adding a battery to the servo amplifier without replacing the motor in the system.
  • To make the control systems efficient, the MELSERVO J2 Super servo systems have high-performance CPUs.
  • The use of an SSCNET interface with serial bus communication at high speeds makes managing these systems smart and consolidated. This connection makes the system quiet and free of wires, while also making it a part of a synchronized network.
  • These servo systems have advanced model adaptive control, which helps the system auto-tune in real-time. In other words, upon attaching a motor, parameters are estimated by the system itself.
  • These systems also have machine simulation functionality. Therefore, a user can see close to the practical behavior of a motor before replacing one.
  • A user can attach peripheral equipment to this servo system easily. These peripherals include cables, connectors, control modules, and so on.
