Execute homing position control in the reverse direction 
and use the ORG switch (from 0 to 1) as the origin. Stops 
when encountering the negative limit switch. 
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 forward direction and encountering the falling-edge of the ORG switch, the 
movement direction is reversed and waits for the rising-edge trigger of the ORG switch. 
3.  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 the initial motor movement is in the forward direction and no falling edge of the ORG switch is 
encountered, a homing failure occurs. 
2.  If a positive or negative limit switch signal is encountered in the process of motor movement, a 
homing failure occurs. 
3.  If no ORG switch signal is encountered in the homing process mentioned above, and time-out is 
triggered, then a homing failure occurs.
