The dual-arm system in the FS100 system, the rotation axis, which is
commonly used to R1 (left arm) and R2 (right arm), is registered as the
base axis (B1 and B2). Following fig. 1-1 “Configuration of Dual-Arm System in the FS100 System” shows the control group configuration of
the dual-arm system in which the shared base axis is used.
Fig. 1-1: Configuration of Dual-Arm System in the FS100 System
NOTE
NOTE
Th
The job created by the former DX100 system configuration
whose rotation axis is registered as S1 cannot be used in
the FS100 system in which the shared base axis is
employed.
In the FS100 system, up to “4” axes can be controlled,
therefore, to the shared axis used dual-arm operation
FS100 system, the external axes cannot be added.

2.1Control Point Fixed Motion During Base Axis Operation
Since the rotation axis is registered as the base axis, by operating the
rotation base axis in the cartesian coordinate, the rotation axis can be kept
moving with each manipulator’s control point at fixed point.
Following figures fig. 2-1, fig. 2-2 and fig. 2-3 show the manipulator’s
control point fixed operation during the base axis operation.

FS1002.2Axis Operation in Cartesian Coordinate System
2.2Axis Operation in Cartesian Coordinate System
At the dual-arm system in the FS100 system, the rotation axis is
registered as the base axis. Therefore, the base coordinate (the world
coordinate) is fixed to the ground even if the rotation axis is operated.
On the other hand, the manipulator moves on the basis of the base
coordinate when it is operated in the cartesian coordinate system.
In this consequence, when the manipulator is operated in the cartesian
coordinate system while the rotation axis is moved from the home position
as shown in fig. 2-4 “Base Coordinate-Based Axis Operation Direction” ,
the manipulator will move in accordance with the ground fixed base
coordinate system.
In this case, it might be difficult for the operator to confirm the
manipulator’s moving direction.
To clear this problem, setting of the robot coordinate to the reference
coordinate when the manipulator is operated in the cartesian coordinate is
made possible.
As described above, when the robot coordinate is set to the reference
coordinate and the manipulator is operated in the cartesian coordinate
system, as shown in fig. 2-5 “Robot Coordinate-Based Axis Operation Direction” , regardless of the rotation axis position, the manipulator’s front
facing direction is recognized as X-axis direction.

The dual-arm system in the FS100 system, creation of jobs specified by
the control groups shown below are possible. Movements shown in the
table 3-1 “Job Configuration” at page 3-1 can be created by the
combination of the groups. For the registration method of the group
combination, please refer to “5.2 Group Combination” in “FS100

NOTE
The dual-arm system in the FS100 system, the rotation axis
motor is commonly used to B1 and B2.
When respective jobs are executed by R1 and R2 parallel to
each other, the base axis (rotation axis) moves on the basis
of a job’s taught position data previously started by
“PSTART” instruction.
On the other hand, when R1 (left arm) and R2 (right arm)
are to be simultaneously moved while the base axis (rotation axis) is rotating, do not move the respective jobs of R1
and R2 in parallel by validating the independent control
function but use the coordinated job (shown in No. 3 or No.
4 in table 3-1 “Job Configuration” ).

4Note
(1) Creation of a job only for the base axis is impossible. If the rota-
tion axis is to be rotated, create a job for “R1” or “R2”.
(2) When operating the both arm (R1 and R2) simultaneously with the
base axis in motion, create a job for “R1 + R2”.
(3) During the job of “R1 + R2”, the taught points for B1 and B2 in the
step should be the same position.
Use text editor, etc. to edit the job’s base axis position. If the
taught positions of B1 and B2 differ even in the same step, following alarm occurs at the time the moving instruction of this step is
executed.
“AL4523: SHARED BASE AXIS CONTROL ERROR [1]”
(4) In the dual-arm system in which the shared base axis is used, the
station twin synchronous function cannot be validated. The following alarm occurs at the time “PSTART SYNC” instruction to start
the station twin synchronous operation is executed.
