♦ The speed actual value is either greater than the maximum speed
for the clockwise-rotating field (P452) or is smaller than the
maximum speed for the counter-clockwise rotating field (P453).
♦ The bit is set to the H signal again as soon as the speed actual
value is smaller than or equal to the corresponding maximum speed.
(See also function diagram 480).
