Pr.47 Creep speed
Set the creep speed after near-point dog ON (the low speed just before stopping
after decelerating from the OPR speed).
The creep speed is set within the following range.
( Pr.46 OPR speed ) ( Pr.47 Creep speed) ( Pr.7 Bias speed at start)
Note) The creep speed is related to the detection error when using the OPR
method with zero signal, and the size of the collision if a collision occurs
during OPR method using the stopper method.
Set a speed equal to or faster than the bias speed at start.
