Technical Specifications:

The MR-J3-40BS is compatible with a range of Mitsubishi servo motors, including HF-MP and HF-KP series. It can effectively manage motors with both 1000 rpm and 2000 rpm ratings, providing flexibility for different application requirements. The design of this servo amplifier is very compact, and it weighs only 2.8kg.

Connections:

The Mitsubishi MR-J3-40BS servo amplifier has several critical connectors to facilitate its integration and operation within industrial automation systems. The Main Circuit Power Supply Connector (CNP1) is designed for connecting the input power supply. The Servo Motor Power Connector (CNP3) is utilized, providing a direct link to the motor for power transmission.

An Encoder Connector (CN2) is employed to connect the servo motor encoder, which is essential for feedback and precise control of the motor's position and speed. For setup, monitoring, and parameter adjustments, the USB Communication Connector (CN5) allows a personal computer equipped with the MR Configurator software to interface with the servo amplifier.

Finally, the I/O Signal Connector (CN3) supports digital I/O signals and analogue monitor output, facilitating the automation system's comprehensive control and monitoring capabilities. These connections collectively ensure the MR-J3-40BS integrates seamlessly into various industrial environments, providing robust and precise control capabilities.

Performance Features:

The MR-J3-40BS utilizes SSCNET, a high-speed synchronous network, for improved communication speed and noise tolerance compared to previous models. This ensures precise and rapid control of the servo motor's speed and direction. The real-time auto-tuning feature allows automatic adjustment of servo gains based on machine characteristics, enhancing performance and ease of use.

The servo motor ensures highly accurate control with a resolution of 262144 pulses per revolution. The system can maintain absolute position information, eliminating the need for a home position return upon power-up or after an alarm event.
