In a method for synchronizing drive units, a target value of the speed of each drive unit of a plurality of drive units speed is computed by determining the product of a maximum speed of the drive unit, a unit-dependent normalized ratio value of the drive unit, and a synchronization factor which is identical for all drive units. Function f=ax2+bx+c are used to describe the destination data within 0 and 1. A data store further can be configured to store tag data from corresponding RFID tags.
