Additive friction torque.
Enables inertia compensation, or selects the source for the
activation signal.
Note: If fieldbus is used as line speed reference source in
parameter 75.02 Line speed reference
value in parameter 75.05 Line ref source cycle time
function to work properly.
Disables inertia compensation function.
Enables inertia compensation function.
Source selection (see Terms and abbreviations
page 152).
Selects the method for estimating the load inertia.
Roll weight is calculated based on supposed amount of
material present on a roll. Parameters of group
Application setup are used.
Resulting roll weight is known, and the inertia is estimated
based on known proportion to the actual roll diameter.
