CHAPTER 4 PARAMETER
Automatic Operation Setting Parameter 4-57

If the home position LS (PA2_12) is not found during travel from the homing starting position in the
reverse traveling unit amount for homing (PA2_09), the motion continues in the starting direction
for homing to search for the home position LS (PA2_12).
(1) The motion starts at the rising edge (OFF → ON) of homing [ORG] in the direction opposite to
the starting direction for homing (PA2_08) at the homing speed (PA2_06).
(2) If the home position LS (PA2_12) is not found during travel by the reverse traveling unit
amount for homing (PA2_09), the motion changes in the starting direction for homing
(PA2_08) at the homing speed (PA2_06).
(3) If the home position LS (PA2_12, PA2_13) is detected, the motion changes in the homing
direction after reference signal detection (PA2_10) at the creep speed for homing (PA2_07).
(4) Upon detection of the first encoder Z-phase (PA2_11) after detection of the home position LS
(PA2_12) during travel in the homing direction after reference signal detection, a travel
continues by the home position shift unit amount (PA2_14), followed by stoppage. The
stopping point changes to the home position and homing completion is turned on and the
homing process is finished.
