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.
