[Detection of home-sensor detection range (home side)]
[1]
Start of home return (Search for the home-sensor detection range)
[2] Detection of a home-sensor detection range (home side) (when the contact B logic is selected:
detection of the falling edge or OFF state of the signal)
[3] Reversing (Search the home-sensor non-detection range)
[4] Detection of a home-sensor non-detection range (home side) (when the contact B logic is selected:
detection of the rising edge or ON state of the signal)
[5] Reversing
[Detection of four points [6], [7], [9], [10] inside the home-sensor detection range. The center of [6], [7], [9]
and [10] is set as the offset reference position.]
[6]
Detection of a home-sensor detection range (home side) (when the contact B logic is selected:
detection of the falling edge or OFF state of the signal), followed by movement to the home-sensor
non-detection range (counter-home side)
[7] Detection of a home-sensor non-detection range (counter-home side) (when the contact B logic is
selected: detection of the rising edge or ON state of the signal)
[8] Reversing, followed by movement to the home-sensor detection range (counter-home side)
[9] Detection of a home-sensor detection range (counter-home side) (when the contact B logic is
selected: detection of the falling edge or OFF state of the signal), followed by movement to the
home-sensor non-detection range (home side)
[10] Detection of a home-sensor non-detection range (home side) (when the contact B logic is selected:
detection of the rising edge or ON state of the signal)
[Offset movement operation]
[11] The offset reference position is determined from the center of [6], [7], [9] and [10].
The position achieved after moving from the offset reference position by the offset travel becomes
the home. The actuator moves from the current position to home.
[12] Home position
Caution
x The actuator always rotates in the specified direction during home return.
If the home return direction is of standard specification, the actuator always rotates in the
counterclockwise direction.
With an actuator of multi-rotation specification, take note that the actuator always returns home in
the counterclockwise direction from positions outside the home-sensor detection range shown in
the figure. The actuator will not take a short-cut.
If you have guided a cable, etc., through an open hole in the actuator, pay attention to the load
received by the cable. The cable may be severed if an excessive load is applied.
