A rough contour with the positions A, B and E which you have already
recorded is now to be refined with the positions C and D. In step 1, the
operator runs the program until position A. In step 2, he positions the
handwheel on position D. He notices that he has interrupted the program one
block too soon. He does not want to save the position, but to run the program
until position B. But NC Start is interlocked because of the movement away
from position A. In step 3 he must first move the position back to A. He can
then execute the missing block to position B in step 4. Now he can teach-in
position C and D.
