014-row circular arc groove type 2-point contact guide that is resistant to large moment load is adopted.Note 1
4-row circular arc groove type 2-point contact guide with less differential slip is used for the linear guide. This guide has less ball differential slip due to its structure when compared to the 2-row Gothic arch type 4-point contact guide and maintains a satisfactory rolling movement even if a large moment load is applied or the installation surface precision is poor. The guide has characteristics that are difficult to malfunction, such as unusual wear and provides excellent reliability.
●F/N/B typeNote 2
For the F type, N type, and B type, two guide frames are laid out on the high rigidity aluminum extruded material frame. Two bearing units per rail, four bearing units in total, support a large load firmly. As a large moment load is mainly converted into vertical force, the moment applied to one bearing unit becomes small to ensure excellent durability.
The F8 series uses a newly developed module guide to greatly reduce the crosssectional area (70 % when compared to F10). The rail is laid out in the full width of the frame to ensure the high rigidity even with compact design. Of course, this series also uses the 4-row circular arc groove type 2-point contact guide.
Note 1. Note 1. Except for T4L/T4LH and T5L/T5LH
Note 2. Except for F8 series/F10/B10.
02Resolver 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.
03Long 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. This greatly contributes to reduction of the customer's maintenance cost.
04Controllers suitable for applications are prepared.
In addition to the robot program operation and pulse train control, a positioner that is operated by specifying a point number was added to the product lineup. Additionally, multi specifications that control multiple robots using one controller are also supported. You can select an optimal controller suitable for your application.

|Specified stroke||A stroke smaller than the minimum stroke may be supported. For details, please consult YAMAHA.|
|Lead beyond catalog||The lead may be changed to that not stated in the catalog. For details, please consult YAMAHA.|
|Origin non-motor specifications||Even when not stated in the catalog, the origin may be changed to the non-motor side. For details, please consult YAMAHA.|
YAMAHA has a wide variety of custom order results other than those shown above. If you have any requirement or request, please feel free to contact YAMAHA.
06N type structure
In this structure, movement is via a nut that rotates while clamped to a screw shaft, the ball screw nut is linked to the hollow motor.
07A high-speed transfer is possible even with a long stroke.
As the ball screw does not rotate, the critical speed is not restricted.
This ensures a high-speed transfer even with a long stroke.
08Double carrier available as a standard
Two carriers can be arranged coaxially by utilizing the features of the nut rotation type.
Space saving and cost reduction can be achieved when compared to use of two single axis robots.
