Mitsubishi MR-JET: Cost and Performance Balance in Mid-Range Motion Control

[Erkan Teskancan]

Mitsubishi Electric's MELSERVO-JET (MR-JET) series offers a mid-range servo drive and motor platform for machines that fall between entry-level and high-performance motion control systems. This series provides robust and reliable performance, free from unnecessary cost and complexity.

MR-JET is ideal for applications where entry-level servo solutions are insufficient, but expensive and complex high-level systems are not required. With simple wiring, flexible connection options, and accurate performance, it offers a suitable alternative for modern, cost-focused machine designs.

### MR-JET Features

• Precise Motion Control: High accuracy preventing position deviation during acceleration and deceleration, lost motion compensation reducing delays caused by motion direction, and path tracking eliminating tracking error.
• Compact and Clean Design: Space-saving in the panel with top and bottom mounted wiring, a compact amplifier that can be mounted side-by-side, and minimized machine space with short motor length and low connector height.
• Single Cable Motor Design: Reduced installation time and wiring errors with a single-touch lock connector integrating power, encoder, and brake cabling.
• Battery-Free Encoders: Reduced long-term maintenance needs thanks to encoders that do not require battery replacement.
• Advanced Connectivity Support: CC-Link IE TSN® for time-synchronized Ethernet communication at 1 Gbps and EtherCAT® supporting communication cycle times down to 125 microseconds.
• Motor Types: Compact rotary HK series motors with 24-bit battery-free ABS encoders and linear motors capable of reaching speeds of 6.5 meters per second.
• Fast Setup and Operation: Stable motion in 0.3 seconds after Servo On, one-touch adjustment with auto-gain optimization, vibration reduction up to 1 Hz, and built-in point table positioning eliminating the need for a motion controller with PLC or GOT control.

The MR-JET series stands out as a reliable solution offering seamless integration into modern automation infrastructures, suitable for applications such as packaging, converting, printing, machine tools, material handling, and general manufacturing.
