In the press UI Substrate Properties window, set the rewinder tension parameter to the value in the table. b. Using the green system web feed button on the rewinder, run the web for a few meters. c. Read the value in the I2P controller screen. It should be within the range indicated in the table. If it is not in the range, write down the value. 2. If the low value is out of range, modify the F_1 and P_1 parameters in the controller as described below. 3. If the high value is out of range, modify the F_2 and P_2 parameters in the controller as described below. NOTE: medium value is dependent on the low and high values. No adjustment is required if the medium value is out of range. Modifying the I2P controller parameters Modify the rewinder 12P controller as shown below. 78 Chapter 2 Procedures

For each of the rewinder tension values (
low, medium and high
) in the table above, do the following:
a.
In the press UI Substrate Properties window, set the rewinder tension parameter to the value in the
table.
b.
Using the green system web feed button on the rewinder, run the web for a few meters.
c.
Read the value in the I2P controller screen. It should be within the range indicated in the table. If it
is not in the range, write down the value.
2.
If the
low
value is out of range, modify the F_1 and P_1 parameters in the controller as described below.
3.
If the
high
value is out of range, modify the F_2 and P_2 parameters in the controller as described below.
NOTE:
medium
value is dependent on the low and high values. No adjustment is required if the
medium
value is out of range.
Modifying the I2P controller parameters
Modify the rewinder 12P controller as shown below.
