As Do Not Latch mode, the axis will start searching EZ signal after the
ORG signal was detected within 5 clock periods.

In Case 2 & 3, the axis will hit and then stop at the edge of EL signal
anyway because the edge of EZ signal locates behind the start point of
Home Move that the axis won’t detect the edge of EZ signal anymore.

never stop if the axis starts from first EZ signal because there is no ORG
signal was triggered prior to EZ searching.

value to command counter and target position counter at the same time.
