A home position return can also be started
anywhere along the dog. The axis moves in
the direction opposite to the home position
return direction, returns to the front end of
the dog, and decelerates to a stop.
After that, an ordinary home position return
is performed automatically.
A home position return can also be started
anywhere past the dog.
In this case, the axis moves in the home
position return direction once. When the limit
switch is actuated, the rotation direction is
reversed, and the axis returns to the front end
of the dog and decelerates to a stop.
After that, an ordinary home position return
is performed automatically.
Note: When the dog cannot be detected during
a home position return from the position
past the dog, the axis stops at the limit
switch located in the direction opposite to
the home position return direction.
The software limit is invalid for a home
position return.
