2.1 Features
This ROIbot is a new concept arm robot controller for which the Built Block System (BBS) idea
has been incorporated to the popular "ROIbot Series".
[Features of axis unit]

Combinations with BBS method
A built block method (building block method) combination is possible by selecting unit parts
such as the axis unit, angle bracket and cable. A system upgrade is possible by further
adding optional parts.

Importance on basic functions
Importance has been laid on achievements and reliability for the main components that
configure the robot axis such as the compact AC servo, highly rigid linear guide and grinding
ball screw, etc. Downsizing has been pursued amid accurate movement.

Cable connection
Inter-axis cables are necessary but often become obstacles.
With the CN box and special shape flexible tube, the wiring and piping can be stored and
vertical or horizontal layout is possible.

Corresponding to the needs of the time - Q. C. D.
High quality, short delivery and low cost is realized by the units standardized with the BBS
method.

Absolute encoder compatible
BA

Series mounts the motor with absolute encoder as a standard. The absolute encoder
will constantly monitor the motor operation through battery backup even when the power is
shut off, so return to origin does not need to be repeated when the system is started.
[Features of controller]

Compact appearance
The controller at 55W × 160H × 134D is as small as the compact AC servo driver that fits
neatly into a panel.

Simple program
The "Easy Mode" for which basic pick & place operation patterns are created as modes is
mounted as a standard.

Mounting of pulse train input port
The axis can be operated directly with an external controller or programmable controller with
pulse generator function, etc. This is used when real-time operations are required.
