63.11 TENSION FDBK INPUT Set to the AI that the tension feedback device is wired into.
The feedback device should be set up to provide zero output (approx.
0…0.3 VDC) at zero tension and full output (approx. 9.7…10 VDC) at
maximum tension.
Hint: To apply maximum tension, feed a rope or strap through the
machine and apply enough weight at the end of the rope to give the
maximum tension. Once this is done, adjust the device's output for
10 VDC. If the maximum output is less than the above recommended
values, it is recommended to review the device's range of operation
for correct sizing. Second, check for correct installation and orientation
of the device. Finally, if the application is correct, use an analog
amplifier to increase the signal to the above recommended values.
Note: Usage of a reduced feedback signal will result in loss of
resolution. A loss of resolution may decrease the performance of the
overall tension regulation. Use of the scaling parameter for the analog
input does not improve signal resolution.
Note: Use of properly rated tension transducers (loadcells) for the
application is required. The transducers should be sized as close to
the application's required maximum tension as possible. For example,
using transducers rated for 400 lbs tension is not acceptable for
applications in which web tension ranges from 5 to 40 lbs.

63.12 TAPER REF SELECT If “KEYPAD” is selected, the value of 63.13 MAX TAPER/% TAPER is
the taper maximum. Otherwise, the taper maximum is a scaled value
of the input selected by this parameter and 63.13 MAX TAPER/
%TAPER. The range of the scaling is 0…100%.

63.13 MAX TAPER/% TAPER If MAX TAPER/%TAPER is not 0%, 03.08 TENSION REF decreases
as 03.13 ROLL DIAMETER increases. At 65.01 MIN CORE
DIAMETER, the taper setpoint is 0%. At 65.02 MAX ROLL
DIAMETER, the taper setpoint is the 63.13 MAX TAPER/%TAPER *
the value from 63.12 TAPER REF SELECT.
