8 Homing
Home Input Detection Direction
Set the home input detection direction. Refer to Homing Start Direction on page 8-7 for details on the
relationship between the homing start direction and the home detection method.
Homing Holding Time
Set the holding time when you set the Homing Method to the proximity reverse turn and holding time
specification. This is the time from when the home proximity input signal (i.e., from when deceleration
starts) until home is defined.

Home Input Mask Distance
Set the home input mask distance in command units when you set the Homing Method to the proximity
reverse turn/home input mask distance. This is the distance from when the home proximity input signal
(i.e., from when deceleration starts) until home is defined.

Homing Compensation Value
After home is defined, relative positioning is performed at the set value to adjust the position of home.
This homing compensation is performed at the homing compensation velocity.
Adjusting the workpiece is sometimes difficult after home is defined. The homing compensation can be
used to fine-tune the position of home after it is determined. This is useful when you cannot easily
replace the home proximity sensor or when home has moved after a motor replacement.
