Thread run-in / thread run-out

The slide requires a run-in distance to accelerate to the programmed
feed rate before starting the actual thread, and a run-out distance at
the end of the thread to decelerate again.

If the run-in / run-out length is too short, the thread may not attain the
expected quality. In this case, the MANUALplus displays a warning.
