[3] Movement speed during OP shift

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