[3] Movement speed during HP shift
When using the HP shift function, the movement speed during the HP shift is set
in "[Pr.56] Speed designation during HP shift". The movement speed during the
HP shift is selected from either the "[Pr.46] HPR speed" or the "[Pr.47] Creep
speed".
The following drawings show the movement speed during the HP shift when a
mechanical HPR is carried out by the proximity dog method. For the
acceleration/deceleration time, the value specified in "[Pr.51] HPR acceleration
time selection" or "[Pr.52] HPR deceleration time selection" is used.
