Center Winder MCO 352
4.3.1 Parameters
19-01 Winder Mode Selection
Option:
[0] *
Rewinder
[1]
Unwinder
19-02 Tension Set-Point
Range:
0
[0-1000]
19-03 Taper Set-Point
Range:
0
[-1100 – 1100]
NB!
Taper is not required in unwinding applications. For unwinding applications, leave this parameter set to 0.
19-04 Partial Roll Diameter Value
Range:
5000
[5000 – 100000]
Function:
Sets the station as either a rewinder or unwinder.
Function:
1000 = 100.0% of full tension. Full tension is the point at which the load cell or dancer produces
a 20 mA or 10 V signal.
Sets the desired running tension. Note that the taper setting will affect the actual tension on the
web. If a dancer system is used, this value sets the dancer running position which would normally
be 500 or center of movement. This parameter is only active if par. 19-19 is set to 0.
Function:
The Taper set-point is used to change the tension set-point as the diameter increases. The result
of the taper function is called the tapered tension set-point. The tapered tension set-point is always
equal to the tension set-point at core. This parameter is only active if parameter 19-20 is set to a
value of 0. A value of 0 = no taper or the tapered tension set-point will always be equal to the
tension set-point. A value of 1000 is 100.0 % taper or each time the diameter doubles from core
the tapered tension set-point will be decreased to 50 % of the previous value. Negative tapers are
also possible.
Function:
100,000 = 100 % of full roll.
Example: If drive has been set-up for a full roll dia¬meter of 40 inches and the roll loaded on
rewind = 10 inches, then the value entered into this parameter would be
10
× 100, 000 = 25, 000
