7 OPR CONTROL
7.5 Dog Cradle Type
The dog cradle method performs a deceleration when the proximity dog turns ON.
Then, movement direction is reversed until the dog turns back OFF. At this point,
movement is again towards the dog sensor but at the set creep speed. As soon as the
dog turns back ON again, movement stops and the OP is defined.
Operation outline is shown below.

2) The proximity dog ON is detected, and a deceleration stop is made.
3) After deceleration stop, it moves in the opposite direction against of OPR at
the OPR speed.
4) If the zero point is passed with the proximity dog OFF, a deceleration stop is
made. (If the zero point is not passed, it continues to move until the zero
point is passed, and then a deceleration stop is made.)
5) After deceleration stop, it moves in the direction of OPR at the speed set in
"
