Homing Start Direction
Select the direction in which the axis starts moving when homing is started. If homing starts while the
home proximity signal is ON in a Homing Operation Mode that includes reversal operation, the axis
starts motion in the direction opposite to the home input detection direction (regardless of the setting of
the homing start direction).
There are four Homing Operation Modes that include reversal operation for a reverse turn. These are
listed below.
• 0: Proximity reverse turn/home proximity input OFF
• 1: Proximity reverse turn/home proximity input ON
• 9: Proximity reverse turn/home input mask distance
• 12: Proximity reverse turn/holding time
