3 Axis Command Instructions
8: Operation for Limit input OFF
1
The axis starts at the homing velocity. When the limit signal in the direction opposite to the home
input detection direction turns ON, the axis starts decelerating to the homing approach velocity.
2
After the axis reaches the homing approach velocity, the axis stops at the first home input signal
after the limit signal turns OFF. This defines home.

• If you perform homing while the limit input on the opposite side of the home input detection direc-
tion is ON, the homing operation starts at the home approach velocity in the home input detection
direction.
• Homing is started and home is defined when the home input signal turns ON after the limit signal
in the direction opposite to the home input detection direction turns ON and OFF again while the
velocity is below the homing approach velocity.
9: Proximity Reverse Turn/Home Input Mask Distance Operation
1
The axis starts at the homing velocity. When the home proximity input signal turns ON, the axis
starts decelerating to the homing approach velocity.
2
The axis moves by the home input mask distance after the home proximity input signal turns ON
and stops at the first home input signal. This defines home.
After the home proximity input signal turns ON, its status does not affect operation. If the speci-
fied travel distance is too short and travel would be completed before the axis decelerates to the
homing approach velocity, an Invalid Home Input Mask Distance error (error code: 742B hex)
occurs when you start homing.

• If you start homing while the home proximity input signal is ON, the operation will start at the hom-
ing velocity in the direction opposite to the home input detection direction. After the home proxim-
ity input signal turns OFF, the homing operation will start at the homing approach velocity in the
home input detection direction.
