Add together the motor currents of all connected servomotors. Multi-
ply the sum by the application-typical simultaneity factor. In the case
of a machine tool this is relatively high, e.g. 0.9, because all axes
can drive into the material at the same time. In the case of a han-
dling system the factor is more likely to be 0.7.
Example: handling system with three axes:
In the following sample, a typical use case with a three-axis han-
dling system is described.
The use case is only an example and does not offer the basis for a
planned application.
