- Outline of the operation
1. The motor will run during the time while the ANGLE +/- key is being pressed and held.)
2. Two motors of the longitudinal direction drive motor and angle control motor work to drive the movements.
3. Analog potential being generated from the angle encoder will be detected to find out the angular movements and
positions. Meanwhile, horizontal intermediate position detections will not be made.
4. When the operation is started after resetting, the system goes into the storage stage once, before proceeding to the
discharging movement to be started up.
5. Angular adjustments can be performed by use of the angle adjusting keys.
6. By pressing the "OPEN" key once again (or by ACC OFF (While the automatic open-close setting is being turned
"ON")), the system starts storage movement.
