IWATA, July 27, 2015 – Yamaha Motor Co., Ltd. (Tokyo: 7272) announced today that it will release two new robot drivers*1, the RDV-X and RDV-P, in September 2015.
With these models, Yamaha Motor has achieved a reduction of approximately 40% in the single-axis robot position settling time, while still retaining compatibility with existing models. In addition, the compact design enables a space saving of approximately 45% in the installation width within the control console, compared with existing models.
As the latest models in the existing RDX and RDP series, the RDV-X and the RDV-P support the servo motor single-axis robot FLIP-X series and the linear motor single-axis robot PHASER series, respectively. Both robot drivers employ the pulse train input method*2 already widely used in current products.
A.Robot drivers are the control devices which drive industrial robot products at high speeds and with a high degree of accuracy.
B.Pulse train input method refers to a standard, widely-used method where the motor rotation amount is controlled with a digital pulse input.
The response frequency has been increased to approximately double that of existing models. This improvement has enabled reductions of approximately 40% in the single-axis robot position settling time.*1
Yamaha Motor has reduced the width of the driver unit by up to 38% compared with existing models, and has also made it possible to install multiple drivers flush with each other by improving heat-dissipation efficiency. These measures have made it possible to reduce the control console internal installation width by approximately 45%.*2
By keeping the parameter settings and pitch for installation holes consistent with existing models, Yamaha Motor has ensured that replacement is simple from both a software and hardware perspective.
