This mode of operation is characteristic for the most highly-dynamic
feeds. They can be found in loaders and handling systems in nearly all
industry sectors.

The dimensioning of this operational mode is mainly made according to
the necessary maximum torque M
max
in the acceleration phase, the
effective torque M

.
This mode of operation is characteristic for drives in printing machines.
