Pr.49 OPR dwell time

When stopper method 1) is set for " Pr.43 OPR method", set the time for the

machine OPR to complete after the near-point dog signal turns ON.

The setting value must be longer than the movement time from the near -point dog

signal ON to stopping with the stopper.

(If the OPR method is not "stopper method 1)", the " Pr.49 OPR dwell time" value

is irrelevant.)

Pr.50 Setting for the movement amount after near-point dog ON

When using the count method 1) or 2), set the movement amount to the OP af ter

the near-point dog signal turns ON.

(The movement amount after near-point dog ON should be equal to or gr eater

than the sum of the "distance covered by the deceleration from the OPR speed to

the creep speed" and "distance of movement in 10 ms at the OPR speed".)
