Part 4 Commands
2-2 Arm-System Control Commands (Dedicated SCARA Command)
The right and left arm systems are defined as the opposite arm systems to the left and right arm
systems, respectively.
The actual arm system that is currently effective is defined as the current arm system.
The arm system to be used for positioning to the target using a movement command is defined as
the target arm system.
The commands used to control the robot's arm system include PTPD, PTPE, PTPR, PTPL, RIGH
and LEFT.
PTPD, PTPE, PTPR and PTPL are control declaration commands for the target arm system in PTP
operation. Therefore, once executed these commands will remain valid while the program is running.
CP operation commands do not accompany change of arm systems during command execution, so
they are not affected by the above commands and the relevant operations will be performed by the
current arm system.
Only one of PTPD, PTPE, PTPR and PTPL, whichever is executed last, will become valid.
RIGH and LEFT are control commands for the current arm system.
2-3 Arm-System Control Commands and Change of Arm Systems
This section explains the arm-system control commands and how the arm system changes in PTP
operation after declaration of each command.
Position Nos. 1 to 4 are set as illustrated below ([1] to [4]).
Movement in the order of 1
o 2 o 3 o 2 o 1 o 4 will be attempted using MOVP commands (PTP
operation).
The robot is initially resting at position No. 1.
Position No. 3 exists inside an area accessible only by the left arm system. (Positioning to this point
cannot be performed with the right arm system.)
Position No. 4 exists inside an area accessible only by the right arm system. (Positioning to this
point cannot be performed with the left arm system.)
