Appendix
Operate a rotational axis in the multi-rotation mode or with short-cut control
Axis-specific parameter No. 67, “Short-cut control selection for rotational movement axis”
 Set this parameter if you want to rotate a rotational axis in a specified direction.
Set the parameter to “1” (short-cut selected) and repeatedly issue a movement command in the same
rotating direction. The actuator will perform multi-rotation operation.
What is short-cut control?
The actuator moves to the position closest to the subsequent position.
 Set value
0: Not selected
1: Selected
2 ~ 5: Reserved by the system
Note: On actuators using a simplified absolute unit, multi-rotation operation cannot be performed
because this parameter cannot be set to “1” (short-cut control selected).
* By selecting this option, the actuator can be rotated in a specified direction.
A table summarizing the information on “Axis operation type,” “Mode selection for linear movement axis,”
“Mode selection for rotational movement axis,” “Short-cut control selection for rotational movement axis,”
“Expression of current position (approx.),” “Software limit +” and “Software limit -,” etc., is provided as “
