Description
Linear friction is an additional friction loss component as a function of
speed. To account for varying loss at different speeds, there are 5
different offsets that can be entered; each one accounting for the
offset needed at the percentage of
proper adjustment of these parameters, use the following procedure.
Procedure 1
1. Place a full roll of product in the section.
2. Set 63.09 TENSION CTL ENABLE to "NOT SEL".
3. Ensure 03.13 ROLL DIAMETER is correct; if not, use the diameter
reset function to set the diameter.
4. Change to LOC mode on the keypad.
5. Set the keypad REF to 5% of
6. Start the drive via the keypad.
7. Increase the speed to 20% of
8. Multiply 01.05 TORQUE by
9. Subtract 63.17 STATIC FRICTION from the result above (step 8.)
and enter this result into 63.18 LINEAR FRICTION@20%.
10. Increase the speed to 40% of
11. Multiply 01.05 TORQUE by
12. Subtract 63.17 STATIC FRICTION from the result above (step 11.)
and enter this result into
13. Increase the speed to 60% of
14. Multiply 01.05 TORQUE by
15. Subtract 63.17 STATIC FRICTION from the product of the result
above (step 14.) and enter this result into
FRICTION@60%.
16. Increase the speed to 80% of
17. Multiply 01.05 TORQUE by
18. Subtract 63.17 STATIC FRICTION from the result above (step 17.)
and enter this result into
19. Increase the speed to 100% of
20. Multiply 01.05 TORQUE by
21. Subtract 63.17 STATIC FRICTION from the result above (step 20.)
and enter this result into
Note: In Unwind sections the friction offset should be entered as a
negative value. Since the web is pulled from the section, the friction
actually increases the amount of tension on the web. Therefore, less
tension torque is required.
Note: The linear friction should be adjusted to maintain +20% tension
regulator output (03.09 TENSION REG OUTPT) as the roll builds.
