Controls the enabled, l=Diameter and thickness
estimation are disabled, but diameter is updated according to actual
thickness:
disabled
direction:
Disables free diameter: O=diameter free; only increase
or decrease on Unwind value
First observer time constant The least value between Taul and
Tau2 is the time constant of diameter estimation while the largest value
is the time constant of thickness estimation
Second observer time constant
The least value between Taul and
Tau2 is the time constant of diameter estimation while the largest value
is the time constant of thickness estimation
Fist winder motor speed threshold; when WMotSpd is below this value
estimations are disabled. When WMotSpd is between WMotThrl and
time constants starts very high and decreses until Taul and
Tau2 when WMotSpd is reached WMotThrl.
It must be below WMotThr2.
Second winder motor speed threshold; when WMotSpd is above this
value estimations are enabled. When WMotSpd is between WMotThrl
and
time constants starts very high and decreses until Taul
and Tau2 when WMotSpd is reached WMotThrl.
It must be above WMotThrl .
Minimum allowed estimated diameter
Maximum allowed estimated diameter
Maximum allowed estimated thickness
When different from zero, estimated diameter
thickness are
resnectivelv set to and
Estimated diameter is set to value when Initialize input is different
from zero
Estimated thickness is set to this value when Initialize input is different
