Set the start direction for when homing is started. To describe the relationship between the home input
detection direction and the definition pattern, we will use the proximity reverse turn with home proximity
input OFF specification. The difference in operation when the homing start direction and the home input
detection direction are the same and when they are not the same is shown below.
