3.2.3 Home-return
Home-return operation is performed when turning the Movement Signal 1 (ST0) on if the home return
has not yet done since the power is turned on.
1) If the operation pattern is “Point-to-Point Movement (Single Solenoid)”
If the home return is not conducted on the operation panel yet, the fi rst Movement Signal (ST0)
will bring the actuator to the home position. After home return operation, it moves to the forward
position and stops (for positioning).
2) If the operation pattern is “Point-to-Point Movement (Double Solenoid) and 3-Point Movement”
After returning to home position, the actuator stops at the backward position (for positioning).
(Home Return Completion)
Movement signal to the forward position (ST1) is invalid till the home-return operation is complete.
