Immediately stops in the servo-on state.
Turn the servo OFF by the input
SVON, etc．
Move the Motor out from the off-limits area or
Move out the Motor manually from the off-limit area after the servo is off.
 When the over travel limit is detected in the middle of Motor rotation, the Motor stops before completing
the positioning, thus the output IPOS (In-position) will not be closed.
 When the over travel limit is detected during the Motor is stopping, the output IPOS remains unchanged
because the Motor is holding the position at where the positioning operation completed right before the
detection of the over travel limit.
