(1) If NOT switch is Off, the initial movement direction becomes forward direction CW. If NOT switch is On, change
of direction is made. The location that meets the first index pulse during operation in reverse direction CCW after
NOT switch is On becomes the Home position.
(2) If POT switch is Off, the initial movement direction becomes reverse direction CCW. If POT switch is On,
change of direction is made. The location that meets the first index pulse during operation in forward direction CW
after POT switch is On becomes the Home position.

Through (7) to (10) methods, the origin position is determined by the Home switch and POT switch.
(7) Upper figure: If POT switch is Off, operation is made at switch search velocity, and the initial movement direction
becomes reverse direction CCW. If the Home switch is On, change of direction is made. Afterwards, the location
that meets the first index pulse during operation in forward direction CW becomes the Home position, and
operation is made at Zero search velocity.
(7) Middle figure: If POT switch is Off, and the Home switch is On, operation is made at switch search velocity, and
the initial movement direction becomes forward direction CW. If the Home switch is Off, the speed is changed to
Zero search velocity. Afterwards, the location that meets the index pulse first during operation in forward direction
CW becomes the Home position.
(7) Lower figure: If POT switch is Off, and the Home switch is On, operation is made at switch search speed, and
the initial movement direction becomes reverse direction CCW. If POT switch is On, change of direction is made.
When the Home switch is changed from On to Off, operation is made at Zero search velocity, and the location
where that meets index pulse first during continuous operation in forward direction CW becomes the Home
position.
(8) to (10) methods have the same positioning concept in homing with the above (7) method except for the initial
operational direction and motions according to the Home switch polarity. Refer to the figure below.
