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 direction to
reverse direction, 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 prox-
imity input signal turns ON and OFF while the velocity is below the homing approach velocity.
5: Home Proximity Input ON Operation
1
When the home proximity input signal 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.
This defines home.
After the home proximity input signal turns ON, its status does not affect operation.

• 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 detection
direction at the homing 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 direction to
reverse direction, 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 prox-
imity input signal turns ON while the velocity is below the homing approach velocity.
