Compensation of acceleration torque

The torque of the drive required for acceleration is defined by the moment of inertia of the system
which is made up of a constant and a diameter-dependent component.
The torque is determined "experimentally" after setting the parameters mentioned before, with deac-
tivated speed controller (limitation of speed to 0).
