Global release of AC Servo System "1S Series" which innovates performance and optimized installation and setup of production line.

June 28, 2016

OMRON Corporation (HQ: Shimogyo-Ku, Kyoto. CEO: Yoshihito Yamada) will make a global release of 16 models of "Middle-range AC servo system with Built-in EtherCAT communications R88D-1SNx-ECT" and of 184 models of "Servo Motor R88M-1x" (hereinafter "1S series") from July 1st, 2016, to further expands the lineup of Sysmac automation platform*1 (hereinafter "Sysmac").

OMRON offers an innovative manufacturing environment to realize the advanced control easily by creating a variety of application functionalities with software and connecting a variety of controller devices. 1S series provides an innovative solution for improving the machine performance and making it easy from design to installation with Automation software "Sysmac Studio" by connecting through machine automation controller "NX/NJ series" and open network "EtherCAT".

Recently, with growing needs for simultaneously startup of production line globally and enhancement of product quality in the production lines of automotive and electronics industries, quick startup for high speed and high accurate production machine is required. Faced on global production sites and a variety of works, the importance of safety measures for production equipment is growing. Under this circumstance, in accordance with application requirements for each customer, each of equipment manufacturers is installing servo system which is key factor for machine performance through design of complicated safety measures and wiring tasks.

1S series provides a unique manufacturing environment which realizes the high speed and high accurate control and achieves from design to installation with "one software" in combination with NX/NJ series and Sysmac Studio, and contributes to an improved machine performance and efficiency of installation.

Key features

Improved machine design

  • Machine design time is reduced by 50% in in-house comparison with previous model with Automation Software" Sysmac Studio"

High-speed and High accuracy control

  • The combination of NX701 and 1S series provide 125us system cycle which is 1/2 in in-house comparison with previous model and industry-leading levels of high speed control.
  • The 23 bit high resolution encoder which is 8 times compared with previous model is available and1S series contributes the development for ultra-high accurate process machine.

Simplification of safety system design

  • FailSafe over EtherCAT (FSoE) is realized by connecting safety control units "NX series" and 1S series via open network "EtherCAT". Safety system can be built easily without wiring for emergency stop of each axis for servo.

Optimization in the control panel

  • Wiring works are reduced by same height throughout the whole power range and the pin layout based on effective wiring.
  • With Battery-free ABS encoder as standard, the mounting of battery is not required and rapid installation of servo system is available.

OMRON brings innovation to manufacturing sites through automation with "integrated," "intelligent" and "interactive" concepts. OMRON is going to work on manufacturing innovation of production site with manufacturers by expanding product lineup for Sysmac and making a world-leading Input-Logic-Output-Robotics + Safety (ILOR+S) technology evolved.

*1 Sysmac automation platform:
OMRON's latest integrated automation platform is dedicated to providing complete control and management of automation plant under one software. Programming based on global standards and global open networks allows for building the globally standardized system. At the core of this platform, the Machine Controller series offers synchronous control of all machine devices and advanced functionality such as motion, robotics and database connectivity. This multidisciplinary concept allows you to simplify solution architecture, reduce programming and optimize productivity.
