In response to the accelerating trend of networked applications in the industrial sector, and to adapt to market changes and customer needs in this new era, Panasonic has intensified its marketing efforts for RTEX bus technology since 2017. It also established the RTEX CLUB (RTEX Partner Club), dedicated to working with Chinese industrial control manufacturers to promote the industry's intelligent and IoT-enabled processes. Recently, we visited Shenzhen Langyuxin Technology Co., Ltd. to gain a firsthand understanding of the development process of Panasonic's RTEX bus solution.
Shenzhen Langyuxin Technology Co., Ltd. is a high-tech enterprise dedicated to the research, development, production, and sales of industrial automation control systems and robotic arm control systems. Especially in the development of multi-axis controllers, Langyuxin is one of the earliest manufacturers in China to adopt RTEX bus technology. Regarding this, Song Pengcheng, the company's general manager, stated: "Multi- axis controllers are a relatively mature market. Whether it's pulse-type or CANopen fieldbus-type, there are already excellent technical solutions. Our choice to enter this market using Panasonic's RTEX bus technology is precisely because of its high stability, high response speed, and high-precision control characteristics. These features can solve many application difficulties in the industry, bring higher system application value to users, and help us establish a differentiated advantage in products and technology in the market."
By adopting Panasonic's RTEX bus technology, Langyuxin provides the following application value to users in the robotic arm industry in its new multi-axis controller solution:
This significantly reduces the overall investment cost for users. This is also a significant advantage of the current Ethernet bus technology solution. The system uses standard network cables for installation and cabling, making system connection very convenient, saving manpower, time and cost for cabling and soldering, and making installation and debugging convenient, with a low system failure rate (less maintenance).
Strong anti-interference capability . Panasonic's RTEX bus technology boasts excellent noise immunity, especially in high-end manufacturing environments such as in-mold inlay processes for computer casings. It ensures that equipment can maintain precise movement positions even after long-term operation, thus meeting the high-speed and high-precision requirements of these high-end applications.
Achieving high-speed, high-precision motion control is crucial. In high-end manufacturing environments, system response efficiency is paramount and a key performance indicator for users. For example, in the robotic arm industry, the typical simulated object-grabbing cycle is approximately 0.6 seconds, while in the system built by Langyuxin using the Panasonic RTEX bus, the simulated object-grabbing cycle can reach 0.3 seconds, providing strong support for efficient production on actual production lines.
Easy to use and debug. The system establishes a data connection with the servo system, integrating the servo system's status display, rigidity and flexibility adjustment, and position adjustment into the controller, greatly reducing the workload of technicians.
Leveraging the superior performance of Panasonic's RTEX bus technology in terms of response speed, motion control precision, and noise reduction, coupled with the high stability of Panasonic's servo systems, Langyuxin's RTEX bus multi-axis controller solution has been applied in numerous fields such as automatic packaging, in-mold embedding/labeling, and glass production lines, helping these manufacturing companies achieve high-speed and high-precision production efficiency.
In the development of Panasonic's RTEX bus-based products, compared to traditional products, the use of data communication simplifies the development process by reducing complex algorithms for sending, receiving, and interference mitigation. It also offers excellent scalability, which helps control hardware development costs. More importantly, Panasonic's RTEX chip is a motion control bus technology specifically developed for motor drives. Its protocol is relatively simple, and it incorporates numerous optimized motion control algorithms and functional modules, allowing developers to directly utilize them. This significantly shortens the development cycle and improves product development efficiency.
Of particular note is that, thanks to Panasonic's extensive R&D experience, manufacturers can obtain comprehensive, rapid, and free development support without needing to find third-party developers. For example, Panasonic's dedicated RTEX website provides detailed information on everything from RTEX basics and corresponding Panasonic and partner products (excluding motors) to RTEX bus technology development materials. It also offers comprehensive technical reference materials on hardware architecture selection, system design and testing, and potential problems, helping R&D personnel solve numerous challenges in the product development process and ensuring high product development efficiency.
