6.2 Hollow Rotary
6.2.1 Operation Range and Home Return
(1) Range of Operation
z Rotational axis/Normal mode
In the absolute position specification mode, the actuator operates in the range shown below.
The maximum range of rotation varies depending on the deceleration ratio.
Deceleration ratio Maximum range of rotation
15 0 to 9999.99
18 0 to 9999.99
24 0 to 7670.99
30 0 to 6140.99
z Rotational axis/Index mode
In the absolute position specification mode, the actuator operates in the range of 0 to 359.99
degrees.
* Refer to the controller specification for details.
(2) Home return
The actuator operates as follows during a home return or upon an absolute reset:
[1] Start of home return
o [2] Detection of home sensor signal o [3] Search for Z-phase, reversing o
[4] Detection of home sensor signal
o [5] Movement by offset distance o [6] Home position
Caution: The actuator always rotates in the same direction during a home return.
If the actuator is of a standard specification, it always performs a home return in the
counterclockwise direction from any position outside the range of Z-phase search shown
in the figure. The actuator does not take a shortcut.
If a cable is passed through the opening, pay attention to the load on the cable. An
excessive load may sever its lead wires.
