7.12.2.6 Angle of tilt
Application with a slope (slide)
For the angle of tilt, only a positive value (slope) can be entered. However, you can dimension an ap-
plication with a slope by specifying a negative speed. If the application is moving on a slope with
negative speed, it goes backwards.
Procedure:
Enter the value of the slope into the Angle of tilt input field.
Enter the value with a negative sign into the Speed input field.

7.12.2.8 Coefficient of friction belt/supporting rollers
7.12.2.9 Velocity
7.12.2.10 Mass of the payload
Symbol Description
β Angle of tilt (gradient)
• The value can be entered in degrees or as a percentage.
• The max. angle of tilt as a first approximation is: arctan
β ≥ arctan(μ
L
)
(static friction between load and belt).
Symbol Description
μ
Gdn
Coefficient of friction between the belt and the supporting surface
• Value can be entered directly or selected from the "Physical coefficients" table.
Coefficient of friction for rolls
Symbol Description
μ
aux
Coefficient of friction between the supporting rolls and the belt
•If μ
aux
= 0, the friction by the supporting rolls is disregarded.
• Value can be entered directly or selected from the "Physical coefficients" table.
Coefficient of friction for rolls
Symbol Description
v Speed of the belt
• Value is entered in the Motion dimensioning step.
Symbol Description
m
L
Mass of payload
• Value is entered in the Motion dimensioning step.
