The actual speed value is less than the set
threshold value (p2161).
BO:
|n_act|  p2161
0 |n_act|  p2161
The actual speed value is greater than or the
same as the set threshold value (p2161).

Application:
To protect the mechanics, the gear stages are not switched mechanically until the speed is less
than the set threshold value.
