When an analog input is set on a PAD parameter, its maximum value is + / - 2048,
therefore in order to have
Line speed
= 100%:
Line speed gain
= [32768 x 16384 / (2048 x 8) – 1] = 32767
(In order to obtain a fine tuning it is necessary to carry out the self tuning procedure of
the analog input).
Ref spd source
Ref speed gain
Their functions are similar to
Line speed source
and
Line speed gain
. They can set the
signal used for the calculation of the inertia compensations and of the speed reference.
With the exception of particular conditions, for example a difference between the line
speed and the speed reference due to the presence of a loop on the material, such values
are set on the same source with the same gains.
Base omega
Value in [rpm] corresponding to the maximum angular speed of the winder/unwinder
(motor shaft side).
Line speed thr
Line speed detecting threshold in %.
When “Ref line speed” is lower than “Ref speed thr” the diameter calculation is stopped.
The diameter is kept at a constant value. When “Ref line speed” overcomes the thresh
-
old, the diameter calculation is enabled with an initial filter corresponding to
Diam init
filter
for the time set in
Diam stdy delay.
At the end of this time the filter will be set
to
Diam filter
.
Diam filter
Filter on the diameter calculation in [ms].
Diam init filter
Initial filter on the diameter calculation in [ms].
Diam stdy delay
Time in [ms] during which the value of
Diam init filter
is kept active after
Line speed
thr
has been overcome.
Diam reset
Diameter reset. When this parameter is enabled, the diameter gets a starting value se
-
lected with
Diam preset sel
.
Diam thr
Programmable diameter threshold as a percentage of
Maximum diameter
. The threshold
overcoming is detected by
Diam reached
and it can be sent to a digital output.
Diam reached
Indication for the overcoming of the diameter threshold.
Diam preset sel
Selector of the starting diameter [0…3].
Diam preset sel
can be set directly via the
keypad or serial line or via two digital inputs programmed as
Diam preset sel 0
and
Diam preset sel 1
, the selection in this case is carried out with a binary logic.
Diam preset 0
0 starting diameter in [m]. The setting of this value must be included between
Minimum
diameter
and
Maximum diameter
.
Diam preset 1
1 starting diameter in [m]. The setting of this value must be included between
Minimum
diameter
and
Maximum diameter
.
Diam preset 2
2 starting diameter in [m]. The setting of this value must be included between
Minimum
diameter
and
Maximum diameter
.
Diam preset 3
3 starting diameter in [m]. The setting of this value must be included between
Minimum
diameter
and
Maximum diameter
.
It can be assigned to an analog input, in this case 10V correspond to
Maximum diam-
eter
and the voltage referring to the minimum diameter is = 10 x (
Minimum diameter
/
Maximum diameter
).
