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.

1: In GX Configurator-QP, the QD75P N/QD75D N are recognized as the QD75P /QD75D .
Therefore, the setting ranges are the same as those of the QD75P /QD75D . To set a value
outside a setting range in GX Configurator-QP, set it through a sequence program or GX Works2.
The setting ranges in GX Works2 are the same as those in sequence programs. (Refer to
Appendix 1.2)
