Pr.49
Creep speed
Set the creep speed after near-point dog ON (the low speed just before stopping
after decelerating from the zero point return speed).
The creep speed is set within the following range.
(
Pr.48 Zero point return speed) ( Pr.49 Creep speed) (
Pr.10
Bias speed
at start)
Note) The creep speed is related to the detection error when using the zero point
return method with zero point signal, and the size of the collision if a
collision occurs during zero point return method using the stopper stop
method.
Set a value higher than the bias speed at start.
