1. A device for controlling electric drives in machinery, the device comprising:
- an electronic control unit for calculating, in advance, electric energy required by at least one electric drive as a function of motion profiles of the at least one electric drive; and
an electric energy storage device located between a voltage source and the at least one electric drive, said electric energy storage device and said electronic control unit together taking a substantially constant electric power out of a connected power supply system at least during a period of time, although the at least one electric drive does not have a constant power input during the period of time.
