(2) Robot controller (SR7000)
• Simple programming.
– A program can be created easily according to highly advanced robot language SCOL.
• Excellent operability
– Teaching of positions, programming, adjustment, etc can be performed according to
the menu selection on the teach pendant.
• Extensive interfaces
– As RS232C three ports, computer and printer interface software are standard-
equipped, a diversity of system structure is possible.
• Easy diagnosis of faults
– A number of self-diagnostic functions allow an operator to smoothly address faults.

1.1.1 Structure
The robot consists of the basic robot, controller and teach pendant connected with the controller,
which is intended for teaching positions and entering programs.
To make the robot do a job, programs and position data are necessary so that the robot can
execute the job.
Normally, such programs and position data should be created and stored in the controller memory
beforehand. When operating the robot, the controller interprets the contents of programs and
gives the robot the instructions on motions according to the program sequence to cause the robot to
do the job.
Programs and position data for one process which are put together are called the task program,
which can also be called the file when they are loaded to and saved in the controller.
As the control unit of the controller uses the SCOL language (symbolic code language for robot), a
task program can be easily created and entered as if you were creating a BASIC program.
Entry of position data is possible in the three manners;
guiding by the robot and teach pendant,
entry of coordinates through the teach pendant and
manual guiding of the robot by the operator
after turning off the servo control.
The teach pendant can be shared by many robots, and automatic operation is possible even when it
is disconnected from the controller.
Also, saving and management of files are very easy, using an optional FDD unit.
In addition to the above, a great number of options and functions including optical sensors for
position data compensation and interface software with a personal computer are also available.
