Description
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.

If MAX TAPER/%TAPER is not 0%,
as 03.13 ROLL DIAMETER increases. At
DIAMETER, the taper setpoint is 0%. At
DIAMETER, the taper setpoint is the 63.13 MAX TAPER/%TAPER *
the value from 63.12 TAPER REF SELECT.
Setting range.
This parameter scales the value that comes in on the selected input
given by 63.10 TENSION SETPOINT. This scaled value is
TENSION SETPOINT.
Setting range.
63.13 MAX TAPER/% TAPER is
