Yamaha Motor Releases New YK1200XG SCARA Robot and RCX341 Dedicated Controller - Achieving Industry-Leading Cycle Times with a 1,200mm Arm Length and a Maximum Payload of 50kg -

IWATA, September 10, 2024 -- Yamaha Motor Co., Ltd. (Tokyo:7272) announced today that it is expanding its SCARA robot YK-XG series with the addition of the YK1200XG model and will launch it alongside the RCX341 dedicated controller in October this year.

The YK1200XG is a SCARA robot designed for the assembly and transport of large and heavy objects. It features a 1,200mm arm length and achieves industry-leading cycle times* with a maximum payload of 50kg.
The RCX341 dedicated controller, while maintaining the compact design of the previous RCX340, increases the maximum output current, providing stable support for the high-speed transport of heavy loads by the YK1200XG.

The YK-XG series SCARA robots are characterized by a completely beltless structure, significantly reducing lost motion, and maintaining high precision over extended periods. Additionally, the direct connection of the end rotational axis to the reducer allows for high permissible inertia on the R-axis, enabling high-speed operation even with offset workpieces. With the addition of the YK1200XG, the lineup now spans a wide range, from 120mm to 1,200mm arm lengths, placing it among the industry's top-class offerings.

The YK1200XG and RCX341 will be exhibited at the Logis-Tech Tokyo 2024, one of the largest logistics equipment and facilities exhibitions in Japan, held at Tokyo Big Sight from Tuesday, September 10th to Friday, September 13th.
*Based on SCARA robots with a 1,200mm arm length. September 2024, current Yamaha Motor data. Standard cycle time: 0.92 seconds (with a payload of 40kg).

《Market Background》
Yamaha Motor is a comprehensive small robot system supplier offering a wide range of products, including linear conveyors, single-axis robots, SCARA robots, vision systems, and controllers for automated production lines. Leveraging the Company's extensive lineup, it strives to enhance efficiency and quality in increasingly complex, diverse, and fast-paced production environments, providing the best solutions to meet our customers' diverse needs.
Among these, since beginning the manufacturing and sale of SCARA robots in 1984, the company has taken initiatives to pursue both lower prices and performance in terms of high speed and high-precision capability, working on the diffusion of robot products in a highly-competitive market.
The YK1200XG is designed to meet the growing global demand for automotive battery manufacturing processes, driven by the rise of electric mobility. As a result, it combines high operational performance and cost-effectiveness, making it ideal for handling weights of 20 to 50kg, the most frequently used range in automotive battery manufacturing and assembly transport lines.

《YK1200XG Main Features》
◎ High Speed
The YK1200XG, with an arm length of 1,200mm and a maximum payload of 50kg, achieves one of the industry's fastest standard cycle times for SCARA robots*. In addition to this standard cycle time, Yamaha Motor also emphasizes tact time in practical applications. By reviewing the reduction ratio and the maximum motor rotation speed, Yamaha Motor has significantly increased the maximum speed compared to previous models. Additionally, the direct connection of the end rotational axis to the reducer ensures an overwhelmingly higher R-axis allowable inertia moment than typical structures that use reducers and belts, enabling high-speed operation even with offset workpieces.

◎ Internal Structure Realizing High Rigidity
The ZR-axis direct coupling structure enables a completely beltless design. The beltless structure significantly reduces lost motion. It can be used for long periods without maintenance, eliminating concerns about belt damage, stretching, or aging.

《RCX341 Main Features》
◎ High Output with Compact Design
Based on the RCX340, known for its advanced functionality that enables high-level facility construction, the Company has reviewed the internal structure of the controller and the inverter circuit. While the casing size remains the same at W355mm x H195mm x D130mm, the maximum output current has been increased. This supports high-speed handling of heavy objects.
The regenerative unit has also been designed to match the controller's height and depth at W80mm x H195mm x D130mm, considering installation within the control panel.
