1.3 Notes on Use
1.3.1 Range of Operation and Home Return
●
Range of operation (position setting)
The angle of movement from the home position determines the position value.
• 330-degree rotation specification: Position specification range = 0 to 330 degrees
• Multi-rotation specification: Position specification range = As specified below.
Mode
Absolute position specification
Relative position specification
Rotational axis, normal mode
-0.15 to +9999.15
-9999.30 to +9999.30
Rotational axis, index mode
0 to 359.99
-360.00 to +360.00
* For details, refer to the specification sheet of your controller.
● Angular velocity and acceleration/deceleration commands
Rotation angle commands are issued based as angular velocity (deg/sec).
Accelerations and decelerations are specified in “G” in operation programs.
Small type: RTBS, RTCS, RTBSL, RTCSL
Rated angular acceleration/deceleration: 0.2 G = 1,960 deg/s
2
Medium type: RTB, RTC, RTBL, RTCL / Large type: RTBB, RTCB, RTBBL, RTCBL
Rated angular acceleration/deceleration: 0.3 G = 2,940 deg/s

1.3.2 Home return direction
The moving end of the output shaft, which turns in the counterclockwise direction, is defined as the
home.
* The multi-rotation specification is available with the direction of axis rotation reversed. On an
actuator with the reverse-rotation specification, home return is implemented in the clockwise
direction.
Caution: If the factory-set home return direction is changed using a parameter, the home return
direction will be reversed but the home position will deviate due to the structure of the
actuator.
Therefore, do not change the factory-set home return direction in the parameter.
