The motion proceeds in the following procedure.
(1) The motion starts upon homing [ORG] (OFF → ON) in the starting direction for homing (PA2_08)
at homing speed (PA2_06).
(2) When 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).
(3) After the home position LS (PA2_12) is detected during travel in the homing direction after
reference signal detection and the first encoder Z-phase (PA2_11) is detected, a travel occurs 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.
