1 When the home proximity input signal turns ON, the axis starts decelerating to the homing ap-
proach velocity
.
2 After the axis reaches the homing approach velocity, the axis stops at the first home input signal
after the home proximity input signal turns OFF
. This defines home.

• If you start homing while the home proximity input signal is ON, the axis performs the following
operation depending on the setting of the homing start direction.
Homing Start Direction Same as Home Input Detection Direction
The axis does not perform a reverse turn operation and homing starts in the home input detec-
tion direction at the homing approach velocity
.
Homing Start Direction Different from Home Input Detection Direction
Operation starts in the homing start direction at the homing velocity, regardless of the status of
the home proximity input signal. If you set the operation at the limit input in the homing start di-
rection to Reverse turn, the axis reverses direction when limit input is detected, and performs a
homing operation in the home input detection direction.
• Homing is started and home is defined when the home input signal turns ON after the home
proximity input signal turns ON and OFF while the velocity is below the homing approach veloci-
ty.

5: Home Proximity Input ON Operation
1 When the home proximity input signal turns ON, the axis starts decelerating to the homing ap-
proach velocity
.
2 After the axis reaches the homing approach velocity, the axis stops at the first home input signal.
This defines home.
After the home proximity input signal turns ON, its status does not af
fect operation.
