Command output
• 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 turns OFF, the homing operation will start at the homing velocity 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.
4: Operation for Home Proximity Input OFF
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
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 detection
direction at the homing approach velocity.
