CHAPTER 4 PARAMETER
(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 (PA2_10), 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.

At the rotation direction selection point with zero speed, zero speed and in-position [INP] are
momentarily turned on. The signal change may fail to be sensed according to some scanning
periods of the host controller.
