[6] 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 first 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).
