18 Drive dimensioning messages
The following chapter describe warning signals, notes and tips that are useful for drive dimension-
ing.
18.1 Applications
18.1.1 Ratio of the tensile forces F
in
/ F
out
> limit value
18.1.2 Ratio of the tensile forces F
out
/ F
in
> limit value
18.1.3 Difference of the tensile forces F
in
- F
out
> limit value
Note!
The ratio of the tensile forces F
in
/ F
out
is xxx. Thus the limit value of yyy is exceeded.
Cause Effects Possible remedies
The Static friction on the interface of
the roll to the material is not suffi-
cient to transmit the difference of
forces.
The roll slips. • Increase the tension on output
side F
out
.
• Decrease the tension on input
side F
in
.
• Increase the angle of wrap.
• Improve static friction.
Note!
The ratio of the tensile forces F
out
/ F
in
is xxx. Thus the limit value of yyy is exceeded.

• Increase the angle of wrap.
• Improve static friction.

is xxx. Thus the limit value of yyy is exceeded.
Cause Effects Possible remedies
The Static friction on the interface of
the roll to the material is not suffi-
cient to transmit the difference of
forces.
The material slips through. • Decrease the force difference be-
tween the input and output
(|F
in
- F
out
|).
• Increase the contact pressure.
• Improve static friction.
