Execute homing position control in the reverse direction
and use the ORG switch (from 0 to 1) as the origin. When
encountering the negative limit switch, the direction is
reversed to locate the origin.
1. The initial movement direction depends on the ORG switch status. The initial movement is in the
forward direction if the ORG switch is active; the initial movement is in the reverse direction if the ORG
switch is inactive.
2. When moving in the reverse direction and encountering the negative limit switch, the movement
direction is reversed and waits for the falling-edge trigger of the negative limit switch.
3. When moving in the forward direction and encountering the falling edge of the ORG switch, the
movement direction is reversed.
4. Then, wait for the rising-edge trigger of the ORG switch as the origin.
A homing failure occurs when the following condition happen:
1. If a positive limit switch signal is encountered when the motor moves in the forward direction, a
homing failure occurs.
2. If no negative limit switch signal is encountered in the homing process mentioned above, and time-
out is triggered, then a homing failure occurs.
