•
Home point is at the first edge of ORG signal when home move executing.
At left or right side of edge depends on home move direction.
•
If axis is not on ORG, the axis will search the edge of ORG as home point.
•
In Case 1, the axis will be stopped immediately when axis detected the
edge of ORG signal but it might stop at anywhere within the range of
ORG signal that means the home position is inaccurate after home move
was executed many times.
While the motion hits the edge of ORG or EL
