Overlapping of blocking zones
If blocking zones overlap, the lowest and highest value of the overlapping zones form a
new zone.
In this case, the status display (output wState or display parameter C00634
) only indicates
one zone (the lower of the two original zones).
Abutting blocking zones
If two blocking zones abut (e.g. 20 ... 30 % and 30 ... 40 %), the limit value between the two
zones (in this example 30 %) is also passed through.
The same applies to a limit range of 0 ... xx %. During zero crossing of the speed setpoint,
"0" speed is output as setpoint. It is possible to exclude "0" speed. However, in this case, the
output speed will remain on the upper limit value when the input setpoint becomes "0".
Tip!
As described above, the acceleration phase starts after the blocking zones have
been passed through. The ramp function generator integrated in the L_Nset
function block limits the progression of the speed. For this reason, the time values
set for the integrated ramp function generator should be as low as possible
whereas the setpoint for the L_NSet function block should be generated by a ramp
function generator with higher time values (e.g. L_MPot
function block).
