Automatic Operation Setting 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.
