When E-Cam moves from current position to the target one, it can rotates at
forward or reverse position. Duing to the cyclic operation, it can reach the
target position either at forward or reverse direction. However, the moving
distance between both is usually different. Use available forward rate to plan
the timing of forward and reverse rotation.
＊Avaliable forward rate: The available max. proportion of forward path
Avaliable forward rate = 0% (0°), reverse path only
: E-Cam current position
: Max. forward rotation limit. Counterclockwise represents
forward direction in the figure.
: Target position is within the range; going trip is at forward
direction
: Target position is within the range; going trip is at reverse
direction.
Avaliable forward rate = 25%, the available max. path is
+90°
Avaliable forward rate = 50%, the available max. path is
+180°
Avaliable forward rate = 75%, the available max. path is
+270°
Avaliable forward rate = 100% (360°), forward path
