Rotary module for robots R series

Introduces the single-axis robot type R, rotation axis model. R type Rotation axis type model Position repeatability accuracy of +/-30seconds (0.0083°). The R type can be used as the rotation axis when combined with other robots, or utilized for a wide range of applications such as index tables. Harmonic drive delivers high-strength and high-accuracy. Feature Resolver with excellent environment resistance is used for the position detector. A resolver is used for the position detector. The resolver has a simple and rigid structure without using electronic components and optical elements. Detection problems due to electronic component breakdown, dew condensation on or oil sticking to the disk that may occur in optical encoders do not occur in the resolver. The resolver provides excellent durability. Additionally, as the absolute specifications and incremental specifications use the same mechanical specifications and common controller, desired specifications can be selected only by setting parameters. Furthermore, even when the absolute battery is consumed completely, the robot can still operate as the incremental specifications. So, even if a trouble occurs, the line stop is not needed to ensure the safe production line. Furthermore, the backup circuit has been completely renovated and now has a backup period of one year in the non-energizing state. Long service life greatly reduces the maintenance cost. As the acceleration is determined by the weight parameter, the service life can be assured when the weight and position of center of gravity are known. YAMAHA's robot uses high rigidity ball screw or guide, it provides excellent durability.
