Mitsubishi Electric Automation Expands Servo Product Line; MR-J2 Super Line Features 400-Volt Series, More Control Types and Networking Flexibility.

VERNON HILLS, Ill. -- Mitsubishi Electric  Automation has expanded its high performing MR-J2- Super (MR-J2S) AC servo product line, making it one of the industry's broadest servo offerings in a single platform.

With the addition 200-230V AC models, the (MR-J2S) lineup now includes a full range of 380-480V AC models and now covers 50W to 110kW capacities. The MR-J2S is available in many different control versions, including analog speed or torque control, digital pulse train, SSCNET, CC-Link, DeviceNet and PROFIBUS-DP high speed networks. The feature rich MR-J2S servo series is also available in several stand-alone motion controller formats.

Long at the forefront of servo auto-tuning technology, Mitsubishi Electric Automation continues to improve this invaluable feature by adding a command frequency response of 550Hz, and loop update times as fast as 55uS for superior overall performance and responsiveness. A wide selection of servo motors - including standard high resolution absolute encoders - allow for greater design flexibility. An easy, high speed network (SSCNET) interface with other Mitsubishi Electric automation platforms, Windows(TM)-based set-up software, and ultra-intuitive MR-Configurator design and diagnostic tools make it a motion system of the highest reliability and performance.

Key enhancements to the MR-J2S include:

Improved Application Versatility. Input voltage selections of 200-230VAC or 380-480VAC allow designing to the needs of a global market. Control options include analog speed, analog torque, pulse-train position, high speed networks such as SSCNET and CC-Link, and built-in motion controller types. All are UL, cUL and CE approved.

Real-time Adaptive Tuning. This feature has revolutionized servo technology, and in 1993 Mitsubishi Electric Corporation was the first to develop and patent this technology, which uses modeled algorithms to dynamically tune the servo. This means that no human intervention is needed to keep the servo running at optimal performance, which is especially useful in applications with ever-changing loads. Real-time adaptive tuning also provides significant time- and cost-savings to designers and machine builders during initial setup.

Superior Frequency Response and Feedback Update Times. These are key factors in determining the overall performance of a servo system. The MR-J2S leads the pack with a frequency response of 550Hz and position, velocity, and current feedback loops of 220uS, 110uS and 55uS respectively, all of which are closed at the intelligent amplifier.

SSCNET. Mitsubishi Electric Automation's high speed serial network dedicated to motion control, SSCNET connects the MR-J2S servo amplifier with the wide range of Mitsubishi Electric scaleable motion products. SSCNET is a robust network that not only supports complex coordinated motion, but also parameter transfer data collection, and extensive real-time diagnostics. The plug-and-play connection offers an inexpensive, time-saving high performance solution.

Advanced Servo Motors. Mitsubishi Electric servos offer a wide range of speed and inertia ratings, enabling a better match to the machine design. With a capacity range of 50w to 55kW, the motor line-up allows the MR-J2S to address applications of any size. All motors come standard with 131,072 ppr absolute encoders. The high resolution encoder is great for positioning as well as low speed stability, and adds the convenience of retaining position while powered down with only a battery needed to activate it.

MR-Configurator. This Windows(TM)-based software package is used to setup, program, and test the MR-J2S. Initial setup and programming is easy and quick with the user-friendly software, which has an extensive help function and drop-downs. MR-Configurator also has many diagnostic functions such as a machine simulator to aid in mechanical design, a machine analyzer to find resonant frequencies of the load and set notch filters, an alarm monitor with history data, and the ability to assign and monitor I/O.

The MR-J2S is an important component in the vast offering of products that enable Mitsubishi Electric Automation to provide single-source automation solutions. Whether standing alone or part of a complete system, the MR-J2S is a servo system that is accepted worldwide for its proven performance, innovation, and ease of use.
