When Direction can be set, the operation when changing the target position differs depending on the setting value.
■For the positive direction/negative direction/current direction
When the target position is changed, the target position will be calculated not from the set position at the change but from the
start position and the Direction set direction.
When the target position is changed to between "start position and the set position at the target position change", the
operation will be reversed to the target position after change, and the control will be performed according to the selection
when having reverse rotation permission selection (Options bit5).
