Yamaha Motor Launches YK400XE SCARA Robot

Delivers Increased Payload and Decreased Cycle Time but Maintains Similar Price

IWATA, September 6, 2019 — Yamaha Motor Co., Ltd. (Tokyo:7272) announced today that it will launch the new YK400XE model 400mm arm length SCARA (horizontal articulated) robot from September 17, 2019.

Despite its low price, the YK400XE is the successor model to the high-precision and high-functionality YK400XR. Thanks to improved rigidity via strengthening of the drive system and arm as well as improved performance of the RCX340 controller, the maximum payload is now 4kg, 1.4 times that of previous models, and the standard cycle time is 0.41 seconds, an approximately 10% reduction. Together, these improvements deliver increased production capacity. In addition, installation positions are fully compatible with the previous model, making upgrading work simple.

Despite the increased maximum payload and improved motion performance, the price is similar to the previous model.

The YK400XE will be exhibited at the China International Industry Fair trade show to be held in Shanghai, China, from September 17 to 21, 2019.

YK400XE Main Features

Maximum Payload of 4kg

Revisions to the drive system and arm structure have increased rigidity and delivered a maximum payload of 4kg, 1.4 times that of previous models. This model is suitable for a wide range of applications, such as assembling, packing, sorting, and inspecting small parts.

Standard Cycle Time of 0.41 Seconds

Revisions to the arm structure have reduced vibration and optimized motion, achieving a standard cycle time of 0.41 seconds, an approximately 10% reduction compared to previous models. The high-speed, low-vibration, and agile movements contribute to improved productivity.

Improved Trajectory Performance

Trajectory accuracy has been improved via the greater performance of the RCX340 controller and the adoption of parameters optimal for the performance area (the actual usage range), thus also delivering greater optimization for operations such as the assembly and sealing of precision parts.

Low Price

Despite improving the basic specifications such as payload, motion performance, and trajectory accuracy, the price is equivalent to the previous YK400XR model. This accessible price enables production site efficiency increases, labor saving, and stable quality.

Full Compatibility with Installation Positions

Installation positions are fully compatible with the previous YK400XR model, making upgrading work simple.

Yamaha Motor SCARA Robots

Research and development of Yamaha Motor’s SCARA robots began with the aim of using them in our motorcycle production lines. Because of this, Yamaha Motor has a 43-year history* in SCARA robots, since the first was installed in one of our factories in 1976. Since then, our product lineup has been expanded, now featuring industry-leading product variations from 120mm to 1,200mm arm length, supporting factory automation in a wide range of industries and fields.

*Sales began in 1984
