Product Announcement from Yaskawa America, Inc. - Motion Division


Sigma-5 Servo System-Image

Sigma-5 offers precise positioning at the highest speed with smooth, vibration-free operation and the easiest start up. For machine builders this means:

  • Shortest cycle time - highest throughput
  • Better product quality
  • Less machine wear
  • Shortest initial set-up time

Features

Highest Performance: Sigma-5 offers maximum efficiency, optimized servomotors, powerful serial encoders, servo amplifiers with the latest microprocessor technology, and powerful ASICs (Application Specific Integrated Circuits).

New intelligent software algorithms lay the foundation for the outstanding performance of the new Sigma-5 series. Precise and fast positioning, highest machine speed, vibration-less motion, smooth operation at the lowest rpm, highest quality, and easy handling make the Sigma-5 ideal for all markets. Due to its optimized autotuning function and its automatic filter function that suppresses oscillations, optimum control will be achieved within minutes - even for a wide range of inertia ratios. For the majority of applications, Sigma-5 does not require any manual adjustment.

User-Friendly Software: One of the main goals of Yaskawa is to offer products and solutions with outstanding user-friendliness. A new version of SigmaWin+ software was therefore developed, which allows for both fast and easy selection of the servomotor and easy set-up of the servo amplifier. The user-friendly intuitive set-up software guides the user through the set-up steps. No expert knowledge is necessary to achieve optimum setting results. At a later stage, the most important functions and features of these programs will also be available as part of a Yaskawa software package.

Fast Set-Up and Installation: The user-friendly set-up software, the optimized autotuning function, and the automatic filter function enable optimum adjustment of the servo amplifiers in a very short time. The servo amplifiers of the Sigma-5 series will adjust automatically to a wide range of inertia ratios.

Manual fine-tuning is no longer necessary. Short set-up times and optimum adjustment results will increase production capacity, improve production quality, reduce changeover time, and reduce machine wear as well.

Versatile Communication with Other Controllers: Another advantage is the flexible communication with the machine controller and other motion control interfaces of European Control Manufacturers. Sigma-5 is able to communicate via several open and Ethernet-based fieldbus systems. The option for the open fieldbus system, MECHATROLINK-II, used worldwide with more than 300,000 axes, is also included in the package. The combined use of Sigma-5 and MECHATROLINK-II significantly reduces the time for installation and set-up, increases system reliability, and supports remote configuration and diagnosis.

Compact and Efficient: New Design with Many Benefits: The servomotors of the Sigma-5 series have been completely redesigned. The number of parts was reduced by about 30%. A new coupling between the motor and the encoder has increased vibration resistance by 100% to 5G and simplified service. A new stator design, advanced winding technologies, and high-density magnets have resulted in increased efficiency and reduction in size. As a result, the energy consumption of the new Sigma-5 is down by up to 30%. The perfect adjustment of the Sigma-5 amplifiers to the new efficient servomotors also allowed for a further size reduction in the amplifier electronics.

Suitable for Many Applications

The major benefits of Sigma-5, such as precise and fast positioning, highest machine speed, vibration-less motion, and smooth operation make Sigma-5 ideal for machines in the fields of electronics, semiconductor, packaging, printing, and machine tools. The new Sigma-5 generation will also be a perfect match for the injection molding and metal forming industries, where high throughput and point-to-point positioning are decisive issues.
