Select the method for calculating weight.
• Based on estimated weight - in this
method weight is calculated based on
material properties
• Proportional to full roll and actual
diameter.
Note: The latter method requires setting of

Define the value for fixed inertia.
Fixed inertia includes sum of the inertia of
the motor shaft, couplings, gear-box and
inertia of an empty roll.
For correct values, see technical description
